What materials are commonly used in injection molding?

Common materials include ABS, PP, PC, PA (nylon), POM (acetal), HDPE, LDPE, and specialized engineering plastics. The choice depends on application requirements for strength, heat resistance, chemical compatibility, and cost.

What causes defects like sink marks and warpage?

Sink marks are typically caused by uneven cooling or insufficient packing pressure. Warpage often results from uneven shrinkage due to material orientation, cooling rates, or mold design issues.

How to fix injection molding problems like flash or short shots?

Flash (excess material) is usually fixed by adjusting clamping pressure or mold alignment. Short shots (incomplete filling) can be resolved by increasing injection pressure, temperature, or flow rate.
