Mold assembly is the last step in the mold manufacturing process, and assembly precision directly affects the quality, lifespan and function of each part. The mold assembly process is based on the technical requirements of the mold and the relationship between them, and the qualified components are connected and fixed as parts until the assembly becomes a qualified mold.When assembling the mold, the assembly accuracy of the mold should be checked within a reasonable range. The assembly precision of the mold includes the positioning precision of the parts concerned, the relevant movement precision, the adaptation precision and the contact only when the precision requirements are guaranteed.
