Injection Molds-Injection Screw Coating FAQs<\/h2>\n\n\n\n
<\/span>01 Chrome plating or PVD titanium plating process for injection molding screws? What is the difference between the two processes?<\/div>\n
\n

Whether to use chrome plating or PVD titanium plating for injection molding screws should be considered according to specific application scenarios, performance requirements, cost considerations and environmental requirements. Currently, injection molding screws are mainly plated, while PVD technology is mainly used for injection molding of high carbon fiber, glass fiber and other hard wear-resistant materials.PVD titanium plating in the application of injection molding screws have many limitations<\/p>\n\n\n\n
