Precision CNC Milling for Injection Molds | Complex Parts Machining

CNC milling for injection molds focuses on producing precision tooling for the plastic injection molding process, enabling the production of complex plastic parts. We machine mold cores, cavities, runners, and ejection systems using materials like pre-hardened steels, beryllium copper, and stainless steel, using our CNC milling machines to achieve tight tolerances and smooth surfaces. Our process ensures dimensional accuracy within ±0.02mm for mold cavities and ±0.01mm for gate features to ensure precise part replication and easy demolding. For example, we mill injection mold cavities with polished surfaces for clear plastic parts and complex core designs for undercuts and threads. Surface treatments like electroless nickel plating or PTFE coating reduce friction and enhance mold release. Our CNC milling supports plastic part manufacturers in creating high-quality injection molds that deliver consistent, dimensionally accurate plastic components for various industries.
