What is the easiest plastic to injection mold?
Speed matters when clients need samples fast or run high volumes. Easy-to-mold plastics help you move quickly.
Polypropylene (PP) and Polyethylene (PE) are the easiest plastics to mold. They have low melting points and excellent flow.
If you need low-cost, fast production, start here.
Why PP and PE Mold So Easily
| Plastic | Melting Point | Flowability | Surface Finish | Reusability |
|---|---|---|---|---|
| PP | \~160°C | Excellent | Clean, uniform | Moderate |
| PE | \~130°C | Smooth | Waxy, soft | High |
PP and PE are ideal for consumer goods, toys, or test batches. These plastics reduce molding errors and cut your costs.
Prime offers express molding services with PP and PE. Our team delivers custom plastic parts within 7–10 days after mold confirmation.
What is the strongest plastic for injection molding?
Strength is critical for parts that must resist impact, pressure, or high load.
Polycarbonate (PC) and Nylon are among the strongest plastics for injection molding. They combine high toughness and excellent thermal resistance.
Here’s how they compare:
Strongest Plastics for Injection Molding
| Plastic | Impact Resistance | Heat Limit | Flexibility | Ideal Use |
|---|---|---|---|---|
| PC | Very high | Up to 135°C | Medium | Safety covers |
| Nylon | High | Up to 120°C | High | Mechanical gears |
We’ve helped clients upgrade from brittle plastics to PC and Nylon, solving performance failures and saving cost in the long run.
At Prime, we provide full support for high-strength plastics. We offer ISO-certified injection molding, ideal for industries with strict safety and performance standards.
