Precision processing of molds

High-end plastic products mass production relies on ultra-precision mold machining technology, jointly achieved by a variety of high-end precision equipment and multi-process collaborative processing. To ensure excellent mold forming quality and meet the strict precision requirements of high-end plastic injection molded parts, the entire precision mold manufacturing process adopts differentiated professional processing technologies, breaking through the limitations of traditional cutting and achieving micron-level tolerance control for reliable mold making services.

In precision mold manufacturing, high-precision CNC machining is firstly applied to mold planes and regular curved surfaces, with professional dimensional precision control to strictly keep dimensional error within ±0.005mm. For difficult machining areas such as sharp corners, narrow grooves, deep cavities and special-shaped complex structures that cannot be completed by traditional cutting, EDM electrical discharge machining is adopted to effectively solve complex processing difficulties and ensure the integrity and accuracy of special mold structures.

For tiny precision structures such as insert positioning holes, thimble holes and limit grooves, slow wire cutting (wire EDM) technology is used for fine machining to guarantee the accuracy of tiny matching structures. Finally, precision grinding is adopted to calibrate mold flatness, verticality and parallelism, controlling the tolerance of core mold matching surfaces within 0.01mm. This multi-process precision machining system fully meets the high-standard precision mass production demands of high-end plastic products, delivering stable and high-quality forming results.
