Injection molding materials
The right resin depends on how the part is used, its working environment and the appearance you need. Tell us the application first; the grade follows.
| Material | Typical use | Notes |
|---|---|---|
| ABS | Enclosures, covers, cosmetic parts | Good impact and surface finish; heat resistance is moderate. |
| PC | Clear or tough housings, covers | High impact and heat resistance; drying and gate design matter. |
| PC/ABS | Electronic housings, appliance parts | Balance of impact, heat and appearance. |
| PA66 | Structural parts, brackets, automotive | Strength and heat resistance; moisture uptake needs attention. |
| POM | Gears, sliders, precision parts | Low friction and good dimensional stability. |
| TPU | Grips, seals, overmolded parts | Flexible; bond and process need review. |
| PBT | Electrical parts, connectors | Good electrical properties and dimensional stability. |
| PP | Living hinges, containers, caps | Tough and chemical resistant; lower stiffness than ABS. |
| PE | Bottles, caps, low-friction parts | Good chemical resistance; soft, waxy surface. |
| PVC | Rigid profiles, electrical housings | Flame-retardant grades available; processing needs care. |
Specific grades, UL-recognized materials and compliance documents are provided with the quotation.
How to choose
- Function — what the part does and what loads it sees.
- Environment — temperature, sunlight, chemicals, moisture.
- Appearance — color, texture, gloss, transparency.
- Assembly — snap fits, screws, bonding, overmolding.
- Compliance — RoHS, REACH, UL and flame-rating documents are provided with the quotation.
Material questions to answer
Send the application, working temperature, expected life, appearance target and any specified grade. If the grade is open, describe the environment and we will discuss options.
FAQ
Can you recommend a material?
Yes, based on the application and environment. Final grade and compliance are confirmed for the specific project.
Can you use a customer-supplied resin?
Possibly. Discuss the grade, documentation and process requirements before committing.
