Material Selection FAQ

Expert guidance on selecting the right material for your injection molding project

For Engineers

How do I choose between ABS and PC?

ABS is more cost-effective with better impact at low temperatures and easier processing. PC offers higher heat resistance (138°C vs 95°C), better transparency, and 30x impact strength of glass. Choose ABS for consumer products and cost-sensitive applications; PC for safety-critical and transparent parts.

When should I use glass-filled materials?

Use glass-filled when you need: 2-3x stiffness (modulus), higher heat deflection temperature, dimensional stability, or metal-like properties. Common applications: automotive structural parts, pump housings, gears, and brackets. Trade-offs: increased anisotropy, harder to achieve Class A surfaces.

What's the difference between PA6 and PA66?

PA66 offers 20-30% higher strength, stiffness, and heat resistance (HDT 260°C vs 190°C) but is harder to process. PA6 has better impact resistance, lower melt viscosity (better for thin walls), and is more cost-effective. PA66 for automotive under-hood; PA6 for consumer and gears.

When should I consider engineering resins?

Consider engineering resins (POM, PPS, PEEK, PEI) when standard plastics can't meet requirements: continuous use above 150°C, extreme chemical exposure, FDA implantable requirements, aerospace specs, or precision mechanical properties. Trade-off: higher material and processing costs.

For Procurement

Can you source specific material brands?

Yes, we work with all major material suppliers: BASF, SABIC, DuPont, LyondellBasell, Solvong, EMS, and more. We can use your specified material or recommend optimal alternatives. All materials come with full traceability and lot-specific data sheets.

What certifications do you offer?

ISO 9001:2015 certified. ISO 13485 for medical, IATF 16949 for automotive, and AS9100D for aerospace. FDA food contact, UL flame ratings, and automotive-grade material certifications available. Full PPAP and documentation support.

What's your quality guarantee?

Parts meet specifications or we replace free. 99.5% first-pass yield backed by incoming material inspection, SPC, CMM verification, and full traceability. PPAP support, first article reports, and comprehensive documentation available.

Do you offer volume discounts?

Yes, our pricing scales significantly with volume. Volume discounts start at 10,000 units and increase at 100,000, 500,000, and 1M+ unit milestones. Multi-year agreements include additional discounts and dedicated inventory programs.

Frequently Asked Questions

Quick answers to common questions from engineers, procurement, and decision makers

For Engineers

What tolerances can you achieve for complex geometries?

We achieve tolerances up to ±0.005mm on critical features using 5-axis CNC and EDM processing. Our DFM analysis helps optimize designs for manufacturability.

Do you provide mold flow analysis before production?

Yes, comprehensive mold flow analysis is included free with every project. We simulate filling patterns, identify potential defects, and optimize gate locations.

What materials do you recommend for high-stress applications?

We offer ABS, PC, POM, Nylon, PP, and engineering resins. For high-stress parts, we recommend glass-filled or carbon-filled polymers with reinforced fillers.

For Procurements

What are your minimum order quantities?

No minimums! We support startups and small businesses with orders from 1 piece to millions. Volume discounts available for larger orders.
