The car plastic injection mould used to produce high-volume injection moulded parts has the advantages of high efficiency, good quality, less cutting, energy-saving and raw materials, and low cost. However, because the car plastic injection mould processing process is complicated, many problems will be encountered. The content of this chapter will Introduce the problems that are easily encountered in car plastic injection mould processing.

　　1. Huge size and weight

　　How to deal with its huge size and weight is a major challenge faced by car plastic injection mould processing plants when processing large car plastic injection moulds. Large-scale car plastic injection mould processing often requires a lot of labor, special equipment, and multiple debugging and clamping, and the processing accuracy of car plastic injection mould is affected by a variety of potential factors, and it is difficult to guarantee.

　　2. Expensive purchase cost

　　The cost of processing and production of various large-scale plastic injection moulds is the cost of professional processing equipment. The machine tools that can make large-scale plastic molding molds are very expensive. The special feature is to arrange complicated processing techniques. Many machine tools are required to complete the entire process from rough machining to finish. Such high initial input costs are also an obstacle for many companies to enter this market. From here, we can see that if the roughing and finishing of large modules can be realized on a suitable machine tool, even if only one setup is required, then many problems will be solved, and the car plastic injection mould machining accuracy can be guaranteed.
