High-End Mold Surface Treatment | SPI & VDI Standard Mirror Polishing & Texture Finishing

Mold surface treatment is the core finishing process that determines the appearance texture and demolding fluency of plastic products, as well as a symbolic procedure of high-end injection mold manufacturing. Multiple customized processes including Class A mirror polishing, matte frosting, fine etching and texture finishing are available according to product appearance requirements, fully complying with SPI and VDI international surface treatment standards. The exclusive mirror polishing process for transparent and high-gloss products achieves a surface roughness of Ra≤0.02μm, completely eliminating appearance defects such as pinpoints, scratches and orange peel patterns. Conventional appearance parts can be customized with uniform matte or exclusive textures. Polishing effectively removes tool marks, optimizes demolding angles, greatly reduces the probability of mold sticking and surface scratching, and significantly improves injection mass production yield and product appearance grade.
