Plastic Injection mould accessories refer to the parts or components of the plastic Injection mould device; it can also refer to the plastic Injection mould parts or components that are re-installed after damage. Precision plastic injection mould is generally composed of many parts, which can be divided into two categories: process parts and structural parts. Process parts have a direct impact on the quality of molding products, and the decisive quality of process parts is the current precision plastic Injection mould accessories are completed by finishing methods.

　　The precision machining process is related to the life of the precision plastic injection mould and the formed products. In the finishing stage of the precision plastic Injection mould parts processing, in addition to the use of slow-moving wire cutting, EDM, and other techniques, the other method is to use half After finishing, heat treatment based on grinding. Then, in the grinding stage of precision plastic injection mould parts processing, it is necessary to control many technical parameters such as deformation, internal stress, shape tolerance, and dimensional accuracy of the parts.

　　In the detailed production practice, there are many difficulties in operation, but in the 15 years of precision machining experience, we can summarize and analyze the methods that can be learned: from the finishing process of plastic injection mould to control the processing of precision plastic injection mould parts, we can carry out adaptive processing for different plastic injection mould parts, different materials, different shapes, and different technical requirements, and provide optional solutions.

　　After controlling the processing process, achieving better processing performance and the economy is the key that most precision plastic injection mould parts processing enterprises attach importance to. The process of precision car parts mould accessories processing is generally: roughing - semi-finishing - (quenching, quenching, and tempering) - precision grinding - electrical machining - fitter trimming - assembly processing.
