This video will show you how KRMOLD precisely manufactures plastic injection molds using Wire EDM (Electrical Discharge Machining). The making of plastic injection molds comprises many stages, and wire EDM is a vital one that guarantees the correctness and quality of the plastic injection mold. Wire EDM is a process by which a thin metal wire is used to accurately cut thick metal, hence producing cutting accuracy beyond the capabilities of conventional CNC machines. This procedure depends on the electrodes and sparks' interaction; wire EDM processes metal components into the intended forms using spark erosion technology. The metal portion to be cut is immersed in deionized water during this process, and the metal wire serves as an electrode generating sparks to remove the metal. Importantly, the metal wire doesn't directly contact the section during cutting, therefore guaranteeing the cutting's accuracy and stability. A thin metal wire is fastened between two diamond guides above and below the workpiece in the Wire EDM process. This wire can move flexibly according to CNC instructions, cutting along the X and Y axes (for more complex shapes, the upper guide may also move along different axes). This efficient movement allows wire EDM to complete complex cutting tasks in a very short time, ensuring that even the complex structures of the plastic injection mold are processed accurately and completely. The capacity to employ extremely thin wires—diameters as little as 20 micrometers—is still another major benefit of wire EDM technology. This feature enables Wire EDM to execute extremely small cuts, so fulfilling the needs of high-precision plastic injection mold manufacture. Wire EDM usually uses a mix of roughing and finishing passes, nevertheless, to maximize processing efficiency and the final quality of the plastic injection mold when compared to sinker EDM.
KRMOLD knows how crucial wire EDM is in plastic injection mold manufacture, therefore strives to utilize cutting-edge Wire EDM technology to guarantee every plastic injection mold's accuracy and quality. KRMOLD will keep you more enthralled with plastic injection mold manufacturing, thereby enabling you to develop a more profound and total grasp of the plastic injection mold production process.
