They all make plastic boxes, so what’s the difference?

Quite a lot, as it turns out. Using the wrong material can result in enclosures that crack under use, turn yellow in sunlight, warp from heat, or fail when exposed to the wrong cleaning agent.

Read on to make a wise choice.

ABS: The Default Choice

ABS is ubiquitous in electronic enclosures. It offers balanced properties at reasonable cost, making it the go-to for most applications.

It machines easily, accepts surface finishes well, and can be painted or printed on to without hassle. Impact resistance is decent enough for normal knocks and drops. Dimensional stability is good – enclosures keep their shape over time.

Temperature is where ABS shows its weaknesses. It softens at around 90-100°C, so avoid it for applications that generate significant heat or operate in hot environments. UV resistance is also poor without additives.

Overall, it’s best for consumer electronics, desktop devices, control panels, and indoor equipment where moderate impact resistance and good appearance matter more than extreme environmental performance.

Polycarbonate: For Tough Environments

Polycarbonate is significantly tougher than ABS. When impact resistance matters, or enclosures face harsh treatment, it brings some strong benefits to the table.

Impact resistance is exceptional, and temperature performance is better than ABS, too.

It costs more than ABS, so you use it where its physical properties justify the price:

• Handheld devices that get dropped regularly
• Outdoor equipment demanding UV resistance
• Housings for heat-generating equipment
• Safety-critical applications where failure isn’t an option

However, chemical resistance is polycarbonate’s weak point. Solvents and cleaning agents that don’t always affect ABS can damage polycarbonate, so they’re sometimes unsuitable for chemically aggressive environments.

Acetal: Precision and Movement

Acetal (POM) is less common for complete enclosures but brilliant for specific applications demanding precision.

Dimensional stability is outstanding. Acetal holds tight tolerances even with temperature and humidity changes. Low friction and good wear resistance suit applications with moving parts – sliding covers, rotating mechanisms, snap-fits that open and close repeatedly.

The trade-offs are cost and appearance. Acetal is pricier than ABS and doesn’t take paint or printing as readily. Surface finishes are limited. Moulding thin walls is trickier too.

Works best for technical housings where precision and mechanical performance outweigh appearance – laboratory equipment, metering devices, industrial controls.

Other Electronics Enclosure Options

There are three other core options:

• ABS/PC blends mix ABS processability with polycarbonate toughness at mid-range cost. Good when you need better impact resistance than pure ABS, without paying the full price of polycarbonate.
• Polypropylene offers excellent chemical resistance and costs less than ABS. Moderate impact resistance and limited appearance options, but handles aggressive chemicals.
• Nylon provides excellent mechanical properties and heat resistance, but absorbs moisture, causing dimensional changes. It needs careful design to accommodate expansion, however.

Making Your Decision

Start with critical requirements. What conditions will the enclosure face? What temperatures? What impacts? Does appearance matter or is function everything?

Key factors to weigh up:

• Environment – indoor vs outdoor, temperature extremes, chemical exposure
• Mechanical demands – impact resistance, precision needs, moving parts
• Cost – initial material and tooling costs vs long-term performance
• Appearance – surface finish requirements, printability

Manufacturing considerations matter too:

• Some materials mould easier than others
• Complex geometries may rule out certain options
• Tooling costs vary by material choice

Choose material that performs properly rather than the cheapest option. Material that fails will cost more than specifying the right one initially. We’re talking warranty claims, replacements, and reputation damage.

At BEC Group, we work through material selection alongside design, balancing performance against cost and manufacturing constraints. Contact us to discuss your enclosure project.

Shipping delays, communication friction, quality issues, and rising costs have companies rethinking their supply chains through and through.

Bringing your injection moulding operations back home offers control and flexibility – but you can’t just pack up your tools and start again.

Nailing reshoring means planning properly. Here’s what you need to sort out.

Your Existing Tooling Situation

Tools are the big question. What condition are they in? Who owns them? Can they even be moved?

Start by retrieving specifications, drawings, and maintenance records from your current supplier. Some are helpful. Others suddenly go quiet, which tells you everything about why you’re leaving. Consider that:

• Worn tools need refurbishment first
• Poorly maintained tools might need extensive repairs or replacement
• Non-standard tools may need modifications to run on different machinery

If your tools are knackered, undersized for your volume, or built to odd specifications, new tooling might be cheaper long-term than trying to salvage what you’ve got.

Contracts and Ownership

Many companies assume they own the tools they’ve paid for, only to discover the supplier retains ownership or has liens against them.

Review your contract for exit clauses, notice periods, and any stipulated minimum order commitments. Some agreements penalise early termination or require months of advance notice.

If your supplier contributed design work, it’s not unheard of that they’ll claim IP rights that restrict where you can manufacture.

Work With an Experienced UK Manufacturer

At BEC Group, we operate state-of-the-art injection moulding facilities suitable for a range of materials and specifications.

Before we quote, we’ll need to understand your part design, material requirements, expected volumes, and quality standards. We can advise on material selection if you’re uncertain – sometimes switching from what you used overseas to a UK-equivalent resin makes economic sense.

We’re happy to arrange facility visits so you can see our operation firsthand. Check out how we work, meet the team who’ll handle your work, and see the equipment we’ll use. We work with automotive and medical clients who demand tight tolerances, so we understand exacting specifications.

Our pricing might surprise you. Once you factor in shipping costs, import duties, and the time you spend managing overseas suppliers, UK manufacturing often costs less than expected.

Plan Your Manufacturing Transition

Reshoring timelines vary.

Once we receive your tools, we need time for installation and testing. We’ll fit them to our machines, run test cycles, and produce samples for your approval before ramping up production.

It’s often sensible to ensure stock covers the transition or to run operations in parallel. It beats running out of stock because the transition is more complex, or time consuming than expected.

Once You’re Over The Hump…

Reshoring is all about gaining advantages that distant suppliers can’t offer – responsive communication, shorter lead times, easier visits, and flexibility when you need changes or have problems to solve.

At BEC Group, we’ve managed dozens of reshoring projects. We assess tooling, handle transitions, and get production running smoothly. We handle everything on-site – design, tooling, moulding – so you have total visibility throughout.

Contact our team to discuss reshoring.

On the upside, proper maintenance prevents most of these issues, and experienced toolmakers who respond fast make the difference between small problems and big disasters.

Read on to learn why.

Why Tools Eventually Fail

Injection mould tools endure brutal treatment. Molten plastic is blasted under massive pressure, thousands of times over. Constant thermal cycling and mechanical battering wear components down, even in well-built tools.

Problems develop gradually – worn ejector pins start to flash on the moulding, damaged gates where plastic enters, eroded cooling channels killing cycle efficiency, worn slides in tools with moving bits.

Nothing breaks suddenly – it tends to be a slow deterioration. Regular inspection catches issues before they cause quality issues or production-stopping failures.

Fixing Things vs Preventing Problems

Reactive maintenance means waiting for failures, then scrambling for repairs. Preventative maintenance is considerably smarter – catch wear during inspections, fix things during scheduled gaps, and keep tools cleaned and properly lubricated.

This involves scheduling planned maintenance windows to disassemble the part, perform maintenance or repairs, and resume production on schedule.

At BEC Group, our toolmakers have 40-plus years of experience. We’d much rather schedule maintenance sensibly than experience tool failures or critical quality issues during a production run.

When Tools Need Changing

Sometimes tools need to be modified rather than just fixed. Design tweaks, material changes, and quality improvements – all might require adjusting existing tooling.

Common modifications include moving gates to improve part quality, adding venting to prevent trapped-air problems, adjusting cooling to speed up cycles, and tweaking cavities when designs change slightly.

Bringing Tools Home

More companies are reshoring tooling after offshore disasters. Long lead times, communication issues, and quality problems are all potentially expensive – not to mention posing critical risks for production. UK toolmaking is considerably more attractive- particularly as upfront costs are on the rise in the Far East.

We champion the Made in Britain philosophy at BEC Group, basing our operations out of Hampshire and working closely with clients across the UK to bring designs to life without the risk of offshore production.

Choose BEC Group for Tool Maintenance

Tool maintenance isn’t exciting, but it’s fundamental to reliable production. Manufacturers delivering consistently versus those constantly firefighting often differ in one thing – how seriously they take tool maintenance.

Ultimately, proactive maintenance costs money upfront but saves far more through robustly preventing downtime, consistent quality, and longer tool life. Emergency repairs always cost more – direct costs, lost production, damaged customer relationships when deliveries slip behind schedule.

Automation that once seemed complicated and expensive years ago is becoming standard.

Meanwhile, materials are comprehensively moving beyond traditional plastics. Sustainability isn’t just marketing fluff anymore – clients want it, the product performs, and legislation is pushing the issue hard.

For manufacturers in the UK and worldwide, this means a whole new side to the injection moulding process.

Here’s what that means in practice.

Smarter Automation

Robots stacking parts and handling repetitive work isn’t new. What’s changed is how intelligent these systems have become. AI quality control identifies defects at a scale beyond the human eye – minute surface problems, tiny colour differences, and dimensional issues you’d need a microscope to catch.

Traditional injection moulding relies on experienced operators who identify when something drifts out of spec by years of practise and knowledge. That skill still matters, but AI can help maintain consistent quality across multiple machines without the need for a permanent operator overseeing things.

However, many manufacturers are still being selective – automate repetitive tasks or quality-critical stages, keeping skilled people for setup and problem-solving. It’s a practical middle ground.

Materials Beyond Plastic

Clients increasingly specify recycled content or bio-based options. Single-use plastic legislation keeps tightening. This trend isn’t reversing anytime soon and will instead likely intensify.

Sustainable material options keep expanding:

• Post-consumer recycled content: Works well at 25-50% for the right application
• Bio-based plastics: Made from corn starch or sugarcane, lower carbon footprint, but don’t always match traditional plastics for toughness
• Better longevity: Durable plastic parts lasting 20 years can beat “eco-friendly” alternatives failing after a couple

The challenge is balancing green credentials with performance and cost. The key is to understand and juggle the trade-offs.

Techniques Worth Knowing About

There are a several modern techniques that might just be the answer to your project:

• Overmoulding combines two moulded components into complex assemblies without the need for separate parts or assembly work.
• Insert moulding places metal or plastic inserts into the mould before injection, creating stronger parts in a single operation.
• 3D printing, which we use at BEC Group to test prototypes before committing to expensive steel tooling.

These aren’t brand new techniques, but they’re becoming more common as clients realise the benefits. Faster production, stronger results, less assembly hassle and reduced end costs.

Why Locality Matters

Recent supply chain chaos taught manufacturers hard lessons about their reliance on overseas suppliers.

Companies that depend on offshore tooling have been facing increased costs, brutal lead times, communication breakdowns, and quality problems that cost fortunes to fix.

UK-based toolmaking and production make more sense now than ever. Having toolmakers, design and materials advice, and production teams on the same Hampshire site means quick responses when problems crop up. Clients can visit, watch their tools being made, and talk face-to-face with people doing the work.

UK manufacturing is not only becoming competitive on labour costs with overseas factories. It also wins on speed, flexibility, quality, and expertise for complex projects. That’s where the value sits.

Industrial injection moulding, when done responsibly, can drive forward environmental solutions.

The question is how far we can push sustainability while still producing durable, functional products.

Read on to learn where the industry stands and what’s genuinely changing at manufacturers like BEC Group.

Working with Recycled Plastics

Recycled plastic is the first line of defence against waste, but not all plastics can be recycled equally.

PET from drinks bottles cleans and reprocesses fairly well, but mixed plastics from household bins present greater challenges. Contamination, degraded properties and colour limitations all affect usability. Each reprocessing cycle can shorten molecular chains, reducing strength.

Recycled content still works extremely well across many applications, though. Products that don’t require virgin materials – such as storage containers, garden furniture, non-structural components, and clothing – can incorporate high recycled content with great success.

Material Selection Beyond Recycling

Bio-based plastics from renewable sources like corn starch or sugar cane offer alternatives to the mainstream. These aren’t automatically superior and their environmental toll is often contested, but they do typically reduce fossil fuel dependency.

From another angle, lighter materials reduce environmental impact as less weight means lower transport energy. Over millions of units, industries have found that weight-related resource consumption adds up to a considerable degree.

And then, durability might be the most overlooked or “hidden” sustainability factor. A plastic component lasting 20 years beats a “biodegradable” alternative that fails after two.

High-quality injection-moulded plastics excel at producing long-lasting products that require less frequent replacement.

Energy Efficiency in Manufacturing

The injection moulding process consumes substantial energy. Melting plastic, maintaining temperatures, and keeping systems online accumulate quickly. Modern machinery has improved significantly, however.

Modern electric injection moulding machines use considerably less energy compared to older hydraulic models. They’re quieter and more precise too.

From there, process improvements can make tangible differences:

• Reduced cycle times – producing more parts with the same energy input
• Better temperature control – preventing wasted heat
• Efficient plant layouts – minimising material handling
• Energy monitoring – tracking consumption per part for measurable improvements

We’ve invested in energy-efficient machines and solar panels at BEC Group and continue seeking opportunities to reduce waste.

Reducing Waste in Production

Every injection moulder generates some scrap. Runners, sprues, rejected parts – it’s inherent to the process.

Production scrap should be reground immediately and fed back into production, albeit diligently and only for appropriate products. Closing the loop minimises waste leaving the facility.

Additionally, optimising mould design and quality control also prevents waste by identifying those all-important opportunities to optimise processes – something that can vary quite surprisingly from project to project.

Moving Forward

Making plastic moulding more sustainable involves dozens of smaller improvements across materials, processes, waste management and equipment. It requires honesty about what works and what doesn’t rather than greenwashing.

Of course, plastic isn’t disappearing. It’s too useful, confers too many advantages to certain products, and is too strongly embedded in modern manufacturing. But how we use it, what we make it from, and what happens afterwards remain vital to sustainability.

Choose well and you’ll have a partner who fulfils your vision to the highest standards. Choose poorly and you’re stuck dealing with delays, quality problems and unexpected costs.

Read on to learn how to choose the best possible injection moulding partner for your project.

Design Support Worth Having

Some moulders simply don’t ask enough questions and don’t support you. The right partner understands how designs translate to manufacture. They’ll tell you if the wall thickness will cause warping, if certain features make parts stick in the mould, or where you’re using more material than necessary.

This feedback matters enormously. Identifying problems with your design after you’ve started production is expensive and frustrating.

Key design services to ask about:

• Design refinement – can they optimise your concept for manufacture?
• Prototype printing – do they test elements of designs before committing to steel tools?
• Mould Flow analysis – will they predict how molten plastic behaves in your mould?
• Design for manufacture advice – can they suggest improvements that reduce cost or improve quality?

These services often separate decent moulders from excellent ones. They can save you money and prevent problems prior to production.

Understanding The Role of Tooling

Mould tools determine your product quality and how smoothly production runs in both the short and long term. This isn’t an area where you want to cut corners.

Plenty of companies send tooling overseas to save money. Local injection mould tooling, such as what we provide at BEC Group, means faster changes, easier communication and quicker problem-solving.

Robust, high-quality injection moulds deliver hundreds of thousands of cycles, sometimes millions. Cheap aluminium tools tend to fail much earlier, which ramps up costs and delays production.

Check whether they handle tool maintenance and modifications themselves too – you’ll probably need design tweaks at some point. We handle all of this at BEC.

Understanding Materials

Plastics aren’t interchangeable. The choice affects product performance, manufacturing cost and production. Good moulders will assist with these decisions, as they really are critical and there’s more choice than many people anticipate.

Broadly speaking:

• ABS handles impacts well and processes easily.
• Polypropylene suits flexible parts and resists chemicals.
• Nylon offers strength and heat tolerance.

Each has trade-offs, and the additives matter too. For example, glass fibres increase strength but wear tools faster, whereas UV stabilisers stop outdoor products from degrading.

There are also regulatory specifications to factor in, e.g., flame-retardant or food contact requirements to meet safety standards.

Quality and Communication

Research quality processes, such as ISO certification, which indicate systematic quality management.

On the communication front, do they explain clearly or hide behind jargon? Do they respond promptly? Do they mention problems early?

Such factors determine whether your project is smooth and streamlined or riddled with delays and aggravation. At BEC, we prioritise transparency around machine capacity and timelines while working efficiently and diligently to complete your project.

Choose BEC Group As Your Injection Mould Partner

The bottom line is to locate a moulding partner that understands your product, delivers quality, and communicates honestly.

Traditional manufacturing methods, while proven, often involve multiple processing steps that can generate significant material waste through cutting operations, assembly rejects, and quality control processes.

Injection moulding, when executed properly, presents an opportunity to streamline filter production and cut waste.

Let’s explore exactly why and how this is the case.

Where Traditional Filter Manufacturing Tends to go Wrong

Most filter manufacturers still rely on similar processes that have been effective for decades. Raw materials get cut, shaped, welded, and assembled through multiple stations. Each step has quality checkpoints, and failed parts get removed from the line.

Assembly is a big issue. A filter might have perfect media, good gaskets, and a sound frame, but if the welded seam fails pressure testing, the whole unit goes in the bin.

Injection moulding produces components that consistently meet specifications, eliminating most of these late-stage failures.

How Injection Moulding Changes Waste Reduction

Injection moulding produces filter components that operate consistently without generating extensive rework or waste. Instead of cutting, welding, and hoping everything fits together properly, you mould parts to exact specifications every time.

Modern tooling eliminates most material waste:

• Multi-cavity moulds produce many parts per cycle
• Precise temperature control prevents warping and rejects
• Computer systems measure exact material amounts needed

When parts are manufactured exactly over huge runs, you essentially stop wasting materials on components that won’t pass inspection.

Precision Enables Sustainable Materials

Computer-controlled injection moulding systems measure exact material quantities needed for each part, eliminating the overuse common in manual processes.

Bio-based plastics, recycled content materials, and environmentally friendly alternatives all complement the overall strategy when you have exact process control and consistent operating conditions.

Our Sustainable Manufacturing Approach

At BEC Group, we focus on sustainability without compromising performance or cost–cost-effectiveness. We consistently strive to identify waste reduction opportunities for each filter design and implement injection moulding solutions that deliver both environmental and business benefits.

We work with manufacturers to understand their current waste challenges, then design tooling and processes that address these issues systematically. The goal is to create manufacturing systems that are both environmentally and financially sensible.

However, simplicity often creates hidden costs that don’t surface until production increases.

Custom injection moulding addresses these problems by creating enclosures designed specifically for your electronics, your brand, and your market requirements.

The investment usually pays back through improved assembly efficiency, better product reliability, and premium market positioning.

Why Generic Enclosures Create Hidden Problems

Standard enclosures weren’t designed for your product. They were designed for maximum compatibility with everything.

This can create some issues that plague cheaper products, such as the hottest component winding up next to your most sensitive chip. Or your main connector hiding behind a support post.

Custom injection moulding fixes this, ensuring components are precisely positioned to maximise form and function.

Meeting Regulatory Requirements Without Workarounds

Regulations for many products are not negotiable and impact design. For example:

• Medical devices need biocompatible materials
• Automotive and similar components must survive specific temperature ranges
• Industrial equipment requires dust and moisture protection ratings
• Food processing components demand materials safe for direct food contact

Custom enclosures ensure that specifications are met early in the design and manufacturing process, thereby ensuring regulatory approval without compromise.

The Cost Problem

Purchase price only tells part of the story with enclosures. Generic options look great on paper, but production often reveals different economics once you start building products.

The hidden expenses pile up:

• Assembly takes longer: Poor fit means more time per unit and more mistakes
• Products fail in the field: Inadequate protection causes quality issues
• Pricing is squeezed: Generic aesthetics mean competing on price
• Changes become expensive: Product updates need new boxes and fresh testing

Most manufacturers discover that total project costs paint a different picture than initial quotes suggest.

Getting Your Enclosure Decision Right

Generic enclosures are suitable for some applications, but they’re not necessarily the smart choice simply because they cost less upfront. Your decision should consider how the enclosure affects assembly speed, product reliability, brand perception, and future product development.

We help manufacturers evaluate these trade-offs honestly. We’ve seen both approaches work and fail depending on the specific situation.

In the intervening 60-odd years, wearables have become everyday technology, used in fitness trackers, key fobs for security access, wristbands used at concerts and smart rings to track sleep.

BEC Group have been involved in the development and manufacturing of body-worn devices for over a decade; working with customers to produce injection moulded wristbands, keyfobs and wellness devices for various industries. With involvement from the initial stages of these projects, BEC has been able to advise on design features to reduce costs and timelines for tooling and injection moulding.

Why Injection Moulding is Ideal for Wearable Devices

Injection moulding is an ideal manufacturing technique for high-volume, complex parts in a variety of plastics, perfectly suited to wearable devices. It presents several other advantages:

• Versatility

Injection moulding offers versatility across materials; choose from waterproof, anti-microbial, skin-safe, soft-touch, sustainable options and more for your part.

It also offers design flexibility including textures, colours, and various styles of branding. These can all be altered throughout the process or for different customers.

• Comfort and Ergonomics

Items worn for many hours, or even days, need to be comfortable. Soft-touch TPEs and TPUs as well as silicones can be combined through overmoulding onto more rigid plastics. Allowing for a soft exterior around a stiffer, functional interior.

• Cost-efficiency and scalability

Once a tool has been designed and made, hundreds of thousands of identical parts can be produced very quickly and at low cost. This makes scaling up to mass-production easy and cost-efficient.

• Accuracy and Repeatability

Wearables often comprise of tiny, precise designs produced to exacting measurements. Injection moulding is perfect for producing accurate parts time and time again- key for consistent performance and quality assurance.

Past wearable technology projects

Branded Wristband for Barclaycard

Working closely with designers Cambridge Design Partnership and Seymour Powell, BEC were selected as UK manufacturers for Barclaycard’s next generation payment device.

After inheriting old aluminium tooling, we made a prototype tool, carried out Design for Manufacture reviews and many materials trials to find the perfect finish for the device. Several clip iterations were needed to get the desired tightness to hold the chip and allow for easy removal.

Once signed off, BEC produced two cavity steel tooling, and mouldings for the two-part overmoulded housing. The band securely held the contactless payment chip, providing a durable, skin-safe method of convenient payment.

Custom Wearable for International Sporting Event

In collaboration with a major card issuer, BEC worked to produce a custom wristband for access, ticketing, and security for an international sporting event. We produced two prototype tools – one for the strap, and one for the clip to hold the Radio Frequency Identification (RFID) chip in securely. These prototype tools allowed us to meet a tight production deadline for the customer, whilst maintaining part quality.

A TPE material was selected for comfort on the body, and ease of moulding and printing onto. The top face of this was hot foiled with the logo of the sporting event. The tool strap was shot blasted to give a premium, satin finish to each piece.

We supplied the customer with several thousand wristbands for the initial event, and several thousand more for a future event with a separate customer.

Key Fob Housing for Chip

We teamed up with an existing customer to help design and manufacture a key fob housing for security access with a built-in RFID chip. After advising the customer on the design, we made a development tool for proof of concept.

To produce the key fob, we used a two-shot process of insert moulding and overmoulding, resulting in the encapsulation of the RFID chip without the need for support for the inner moulding.

For added decoration, and brand identification we embossed the customer’s logo into the tool – creating a raised icon on the moulding for a sleek, identifiable finish.

What Wearables Can BEC Group Help Me Manufacture?

As the wearable tech world grows across payments, medical and wellness, events and more, so do the options for manufacturing. BEC work closely with customers throughout the design and development phase to ensure designs will work well and be cost effective once tooled and moulded.

What Makes LDPE and HDPE Different

The key difference lies in molecular structure. Low-density polyethylene (LDPE) has branched chains that create flexibility. High-density polyethylene (HDPE) has linear chains that pack tightly together for strength.

A seemingly small density difference creates vastly different performance characteristics during the injection moulding process. The branched structure of LDPE makes it softer and more pliable, whilst HDPE’s linear structure produces a stiffer, stronger product.

Understanding the Key Properties

LDPE wins the flexibility contest hands down. You can bend it, twist it, or even tie it in knots at room temperature without cracking. It also handles most common chemicals without damage.

HDPE, however, thrives in strength:

• Tensile strength: Roughly twice that of LDPE in most grades
• Chemical resistance: Handles acids, bases, and solvents that would attack other plastics
• Temperature range: Stays stable from -40°C up to 120°C in many applications
• UV resistance: Won’t degrade in sunlight like many other thermoplastics

The trade-off is obvious – more strength means less flexibility. HDPE won’t bend much before it snaps.

Where Each Material Excels

LDPE built its reputation in packaging, with applications ranging from grocery bags to squeeze bottles for ketchup and shampoo rely.

Wire insulation is another natural fit. Cables get bent, twisted, and flexed constantly. LDPE can handle that abuse whilst protecting the conductors inside.

HDPE dominates the heavy-duty applications. Garden furniture made from HDPE, for example, will outlast most alternatives. In essence, anything that needs to maintain a strong, rigid structure.

Processing Differences

LDPE behaves well during plastic moulding. Lower processing temperatures save energy and reduce cycle times. It flows easily into complex shapes and thin sections. Stress cracking rarely occurs during cooling, resulting in fewer rejected parts.

HDPE needs more heat to process properly, but it compensates with some other useful characteristics. Higher melt strength means you can mould thinner walls without breakthrough, and better dimensional stability reduces warping problems.

Making the Right Call

In sum, flexibility requirements point toward LDPE. Strength and chemical resistance demands favour HDPE.

At BEC Group, we’ve seen both materials succeed and fail in various applications and will work with you to understand your part or product and the type of plastic it will benefit from.
