Types of Coating Defects
2026-05-11
When a coating is applied to a surface, many problems or conditions may occur. Although they may not be obvious at the time, they can cause issues later during the coating’s service life. Premature corrosion of the substrate is often caused by coating failure. One of the reasons is the presence of defects in the finished coating. The main defect types include: Sagging & Runs Due to the effect ...

Injection Mold Design for Connectors: Precision Assurance and Structural Innovation
2026-03-31
Key Considerations in Connector Injection Mold Design ■ Mold Precision Classification Based on connector accuracy requirements, molds are classified into three levels: standard (tolerance ±0.05 mm), precision (±0.02 mm), and ultra-precision (±0.01 mm). For example, a smartphone connector with dimensions of 10 mm × 5 mm × 2 mm and a tolerance of ±0.01 mm requires ultra-precision mold design, combin...

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...
