Welcome to a video showcasing the daily operations of the KRMOLD factory. This video will demonstrate how plastic injection molds are manufactured using EDM.
EDM technology is a non-traditional machining method that, with unique electrical discharge principle, can easily handle machining tasks involving various complex shapes. Whether it's deep grooves, narrow slits, irregularly shaped holes, or complex three-dimensional surfaces, EDM, with its precise discharge control, can accurately replicate the shape of the electrode onto the workpiece, achieving machining precision that is difficult to achieve with traditional methods. For the fine textures and complex patterns commonly found in plastic injection molds, EDM can also add unique decorative effects to the mold surface without affecting the overall performance of the plastic injection mold. EDM has a unique advantage in machining high-hardness materials. Materials commonly used in plastic injection mold manufacturing, such as cemented carbide and hardened steel, are extremely difficult to machine with traditional cutting tools. However, EDM is not limited by material hardness. Through the high temperature generated by the discharge, it instantly melts and vaporizes the material, achieving efficient machining of high-hardness materials, greatly expanding the range of mold material choices and providing more possibilities for improving plastic injection mold performance.
