Possible Causes of Flash in PEEK Injection Molded Parts
2026-03-26
Flash in PEEK Injection Molding: 9 Common Causes 1. Part projected area exceeds the injection machine’s maximum allowable area When the projected area of the part exceeds the maximum allowed by the injection molding machine, the nozzle may not adequately cover the entire surface, resulting in flash on the part. 2. Incorrect mold installation or uneven single-direction force If the mold is installe...

The Critical Role of Heat Treatment in Thermoplastic Composites
2026-03-04
The Critical Role of Heat Treatment in Thermoplastic Composites The Critical Role of Heat Treatment in Thermoplastic Composites Thermoplastic composites (TPCs) offer significant advantages over traditional thermoset composites, including rapid processing and the ability to be reheated and reshaped multiple times. Their melting and solidification involve physical changes rather than chemical reacti...

Key Factors That Determine Cooling Time in Injection Molding
2026-01-30
Cooling Time in Injection Molding In injection molding production, the cooling time of plastic injection-molded parts accounts for approximately 80% of the entire molding cycle. Insufficient cooling often leads to warpage, deformation, or surface defects, which directly affect product dimensional stability. Properly balancing injection time, packing/holding time, and cooling time is essential for ...
