Spark discharge machine is a special machining method that uses the electrical erosion generated by the pulse discharge between the two electrodes immersed in the working fluid to erode conductive materials. It is also known as electric pulse and mold discharge machining machine. It is mainly used for a series of plastic molds, such as automotive plastic molds, medical plastic molds, and home appliance plastic molds.

Wire cutting processing of mold parts with micro structures, mainly processing complex shaped mold parts and processing hard conductive materials

The plastic raw materials used in the injection molding process are diverse, and the types and forms of mold design are also diverse. The level of familiarity of operators with specific injection molding machines, as well as the operational skills and practical experience of workers, also vary. At the same time, the objective environment (such as environmental temperature, humidity, and air cleanliness) will also vary with seasons. These objective and subjective conditions jointly determine the occurrence of defects in injection molding products.

In the competition of the injection molding industry, achieving customer satisfaction to a greater extent through quality management is the significance of every enterprise or organization. Therefore, quality is not only about whether the product meets specifications, but also includes the overall direction of customer satisfaction. Customer satisfaction, in a broader sense, includes multiple aspects such as delivery time, service, price, etc. If science and technology are the primary productive forces, then quality is the most direct manifestation of a company's strength.
