At Goldcattle, we’ve been crafting custom plastic parts for 15 years—we know this stuff inside out. Whether you need a tiny sensor housing or a large industrial enclosure, we’ve got the skills, tools, and materials to make it happen.

Injection Molding

We melt plastic resin and shoot it into precision molds under high pressure—dude, this is how we make complex parts with ±0.02mm tolerance! Perfect for high-volume production runs where consistency is key.

Our machines can handle shot weights from 0.5g up to 2000g, with clamping forces ranging from 50 to 2000 tons. We use advanced mold temperature control systems to ensure perfect part quality every time.

Pro tip: Best for housings, connectors, structural components, and high-volume production

CNC Machining

Computer-controlled tools carving solid plastic blocks—great for prototypes or low-volume runs with intricate details. We have 3-, 4-, and 5-axis machines that can handle parts up to 1200mm in size.

The best part? No expensive molds needed! We can go from CAD file to finished part in as little as 24 hours. Perfect for testing designs before committing to mass production.

Pro tip: Quick design changes? Complex geometries? This is your guy!

3D Printing

Layer-by-layer magic with ABS, PC, nylon, or specialized resins—perfect for rapid prototyping or crazy geometries that are impossible to mold. We use FDM, SLA, and SLS technologies.

Our largest 3D printer can make parts up to 600mm x 500mm x 600mm. We even offer metal 3D printing for hybrid parts that need both plastic and metal components.

Our shielding solutions can achieve up to 80 dB of attenuation across a wide frequency range (10 kHz to 10 GHz). We can also provide Faraday cage enclosures for complete signal isolation.

Perfect for: Medical devices, military equipment, communication systems

Flame Resistance

We use flame-retardant additives (both halogen-based and halogen-free) to meet UL94 V-0 standards. This prevents fire spread in critical applications like power adapters and industrial control gear!

Our flame-resistant materials can also meet more stringent standards like UL94 5VA (for thicker parts) and IEC 60695-11-10 (glow wire testing). We can provide custom formulations for specific requirements.

Perfect for: Electrical enclosures, power tools, aerospace components

Thermal Management

We integrate heat-dissipating ribs, graphite films, or metal inserts into plastic parts to improve heat transfer. This prevents overheating in high-performance devices like gaming laptops and processors!

Our thermal solutions can improve heat dissipation by up to 300% compared to standard plastic parts. We also offer liquid cooling integration and phase change materials for extreme heat applications.

Perfect for: LED lighting, power electronics, automotive components

Chemical Resistance

We select special materials or apply protective coatings that resist oils, solvents, cleaning agents, and harsh chemicals. This ensures long-term durability in medical devices or industrial electronics!

Our chemical-resistant parts can withstand exposure to acids, bases, fuels, and sterilization processes (autoclaving, EtO gas, gamma radiation). We test all materials against specific chemicals your application may encounter.

Perfect for: Medical devices, laboratory equipment, industrial machinery

Surface Finishes

We apply matte textures to reduce fingerprints, glossy coatings for aesthetics, or anti-scratch treatments (like hard coats) to extend part life in consumer devices!

Which material is best for high-temperature electronic parts?

LCP (Liquid Crystal Polymer) and PPS (Polyphenylene Sulfide) are absolute beasts for high temps—LCP can handle up to 260°C continuously, while PPS works great at 200°C. PC (Polycarbonate) is solid for moderate temps up to 120°C in housings and structural parts. If you need something even more extreme, we can also get you PEEK (260°C) or PEI (180°C) materials!

Can you make parts with really tight tolerances?

Hell yeah! Injection molding can achieve ±0.02mm tolerance for small parts like connectors or sensors. CNC machining? Even tighter at ±0.01mm for critical fits. We use state-of-the-art machines and metrology equipment to ensure every part meets your exact specifications. For super precision applications, we can even do micro-machining down to ±0.005mm!

Is custom really cost-effective for small production runs?

Absolutely! For 100-1,000 units, CNC machining or 3D printing skips expensive mold costs, making them way cheaper than injection molding. For 1,000-10,000 units, we can use aluminum molds that are more affordable than steel molds. And for 10,000+ units? Injection molding becomes way more economical as per-unit costs drop significantly. We’ll always recommend the most cost-effective option for your specific needs!

How do plastics help with device lightweighting?

Oh man, this is where plastics really shine! ABS and PC weigh 30-50% less than metal alternatives but keep the same (or better) strength. For example, a plastic laptop housing weighs about 40% less than an aluminum one but still provides excellent protection. This is a total game-changer for portable electronics (laptops, wearables) and battery-powered devices where every gram counts. We’ve helped clients reduce device weight by up to 60% by switching from metal to plastic!

Can plastic parts be recycled and are they environmentally friendly?

Most definitely! ABS, PC, PP, and many other plastics are recyclable in most municipal systems. We offer recycled-content plastics (up to 100% recycled material in some cases) and design for recyclability using mono-material construction (no mixed materials that are hard to recycle). We also use biodegradable plastics for applications where sustainability is a top priority. Plus, plastic production uses less energy than metal production—so you’re reducing your carbon footprint too!

What’s the typical lead time for custom plastic parts?

It depends on the complexity and quantity, but here’s a general breakdown: Prototypes (1-10 units): 1-3 days with 3D printing, 3-7 days with CNC machining. Small production runs (10-1000 units): 1-2 weeks. Medium runs (1000-10,000 units): 2-4 weeks. Large runs (10,000+ units): 4-8 weeks (includes mold making). We also offer expedited services for urgent projects—we’ve turned around prototype parts in as little as 24 hours before!

Do you offer design assistance and engineering support?

Absolutely! Our team of 15+ engineers has decades of experience in plastic part design. We can help you optimize your design for manufacturability (DFM), select the right materials, and ensure your parts meet all performance requirements. We use CAD software (SolidWorks, Pro/E, AutoCAD) and FEA simulations to test designs before production. We even offer free design reviews for potential clients—just send us your CAD files and we’ll give you our expert feedback!

What quality control measures do you have in place?

We take quality very seriously! We’re ISO 9001 certified and have a comprehensive quality control system that includes: incoming material inspection, in-process testing, final inspection, and traceability for every part. We use CMMs (Coordinate Measuring Machines) for dimensional inspection, optical comparators for visual inspection, and various testing equipment for mechanical and thermal properties. We also provide detailed quality reports with every shipment—you’ll know exactly what you’re getting!

Do you work with startups and small businesses?

We love working with startups! In fact, we’ve helped launch over 200 new products from startup companies. We understand that startups have unique needs—lower minimum order quantities, flexible payment terms, and fast turnaround times. We offer special startup pricing and can even help with crowdfunding campaigns by providing prototype parts for your campaign videos. Some of our biggest clients today started as small startups with just an idea—we’d love to help you grow too!
