Materials
The right resin for the part, not the easiest one to run
What we mold most, and what each is good for.
Resins we run
| Resin | Good for | Watch out for |
|---|---|---|
| Polypropylene | Living hinges, containers, low-cost housings | Shrinkage; tight tolerances are hard |
| ABS | Enclosures, cosmetic parts, easy to paint and plate | UV exposure without an additive |
| Polycarbonate | Clear parts, impact strength, lenses | Stress cracking with some chemicals |
| Nylon | Gears, clips, structural parts, wear | Moisture uptake changes dimensions |
| Acetal | Gears, bearings, snap fits, low friction | Poor bonding and painting |
| TPE | Grips, seals, overmolds | Bond to the substrate needs testing |
| Glass-filled grades | Stiffness and heat, structural parts | Tool wear and warp |
