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?
