At our company, we specialize in CNC mold parts that are the backbone of precision manufacturing. Leveraging state-of-the-art CNC technology, our expert team crafts intricate components. From injection molds for consumer plastics to die-casting molds for metal products, each part is designed and machined to exacting standards. We ensure high-quality finishes, tight tolerances, and durability, empowering industries to bring their innovative designs to life.
Milling is a cornerstone process for CNC mold parts. It can create complex cavities, cores, and parting surfaces. For instance, in injection mold making, milling precisely shapes the negative space for the molded product. Multi-axis milling machines enable intricate 3D geometries, like the detailed contours of a smartphone case mold.
CNC precision turning is crucial for producing cylindrical mold components such as ejector pins and mold cores. The workpiece rotates while the cutting tool forms a smooth, accurate diameter. In die-casting molds, precisely turned pins ensure proper ejection of cast parts. It guarantees the right fit and function, as seen when a lathe shapes a metal rod into a key mold component.
Drilling creates holes for cooling channels, ejector pin holes, and venting in molds. In plastic injection molds, accurate drilling positions cooling channels to control part temperature. CNC drilling ensures holes are drilled at the right angles and depths, preventing issues like warping.
Grinding refines the surface finish of mold parts, especially critical mating surfaces. For high-precision molds, grinding reduces surface roughness, ensuring tight seals and smooth operation. It polishes surfaces like the parting line of an injection mold, minimizing friction and wear.
EDM is indispensable for machining complex and hard-to-reach features in mold parts. EDM machining services can create ultra-fine details in hardened tool steel, like the micro-textures on a cosmetic mold. The process uses electrical discharges to erode material, allowing for shapes that are impossible with traditional machining.
For CNC mold parts, we offer a wide array of materials. High-quality tool steels like P20 and H13 are favored for their durability and heat resistance, ideal for injection and die-casting molds. Aluminum alloys provide lighter options for certain applications. When it comes to surface treatment, nitride coating on steel molds boosts hardness and wear resistance. Electroplating can enhance corrosion resistance and release properties, ensuring smooth part ejection. Our choices of materials and treatments are tailored to meet diverse mold requirements and extend service life.
