Sharing Tips on Surface Treatment Techniques for Injection Molding
Injection molding is a widely used modern manufacturing process that produces complex-shaped parts by injecting molten plastic into a mold and cooling it for solidification. However, injection-molded parts often exhibit surface defects (such as burrs, flow marks, sink marks, or uneven gloss) due to material properties, mold design, or process parameters, directly affecting product appearance and functionality.
