The Four Pillars of Injection Molding
ABS, PC, PP, and PA account for over 70% of all injection molded parts globally.
ABS — The Versatile All-Rounder
- Strengths: Excellent surface finish, good impact resistance, easy to mold
- Limitations: Poor UV resistance, limited chemical resistance
- Best for: Consumer electronics, automotive interiors, toys
Polycarbonate (PC)
- Strengths: Highest impact strength, optically clear, heat resistant
- Limitations: Poor chemical resistance, requires careful drying
- Best for: Safety products, lenses, medical devices
Polypropylene (PP)
- Strengths: Best chemical resistance, flexible, low cost
- Limitations: Poor UV resistance, lower strength
- Best for: Packaging, containers, living hinges
Polyamide (PA/Nylon)
- Strengths: Excellent mechanical properties, chemical resistant
- Limitations: Absorbs moisture, requires drying
- Best for: Gears, bearings, automotive parts
