Wire Electrical Discharge Machining (Wire EDM)

◉ Process principle: Using a thin metal wire as the electrode, the metal is melted and vaporized by the high temperature generated from pulse discharge, and the material is cut and formed according to the preset trajectory.

◉ Application Scope: Wire EDM is suitable for processing high-precision parts such as thin walls, narrow slits, and complex contours of precision molds, as well as the processing of hard conductive materials.

◉ Advantages: It has extremely high machining precision, without having to consider the problems of tool wear and rigidity. It can achieve machining of tiny dimensions and has good surface quality of the machined surface, especially suitable for the manufacturing of precision molds.

◉ Process principle: Heat treatment controls the processes of heating, holding, and cooling of metal materials, and changes their microstructures to obtain the required mechanical properties (such as hardness and toughness).

◉ Application scope: Widely applied to various mold materials (such as Cr12MoV and H13 steel) to improve wear resistance, strength, or eliminate internal stresses, especially suitable for mold parts subject to high loads and high temperatures.

◉ Advantages: Significantly extends the service life of molds (reduces wear and deformation), optimizes the cutting performance of materials, reduces the risk of cracking, and is a key process to ensure the reliability of molds.

◉ Process principle: Accurately assemble the processed and inspected mold parts according to the design requirements, and debug the opening and closing of the mold, injection molding parameters, etc. through mold trials to ensure its normal operation.

◉ Application scope: Applied to the final stage of injection mold manufacturing to ensure that the mold meets the accuracy and functionality requirements before mass production.

◉ Advantages: By simulating production and debugging in advance, the assembly accuracy of the mold and the molding effect are guaranteed, the risk of failures during mass production is reduced, and the production efficiency and the yield rate of good products are improved.

Assembly and Adjustment
