High precision mould processing in Dalian

Die processing refers to the processing of molding and blank making tools, in addition to the shear die and die cutting die. Normally, the die has two parts: the upper die and the lower die. The steel plate is placed between the upper and lower molds, and the material is molded under the action of the press. When the press is opened, the workpiece determined by the mold shape or the corresponding scrap can be obtained.



The machining precision requires a pair of moulds, which are usually made up of die, punch and die frame, and some may also be multiple parts. So the combination of the upper and the lower modules, the combination of the insert and the cavity, and the combination of the modules all require high machining precision. The precision of the precision die is often m. The process of die manufacturing is rather complex. Generally, it includes mold blank preparation, rough machining, semi finishing, heat treatment, finishing, surface treatment, mold assembly and machine debugging. The billet preparation stage is to provide the corresponding blank for the mold parts, and to establish the processing technology. Of course, the processing technology should be worked out according to the accuracy requirements of the parts and the type of materials.



The die processing materials in Dalian should have good heat resistance and dimensional stability, which require a lower expansion coefficient and stable structure of the die processing materials. The expansion coefficient of the steel in the plastic mold is smaller, the second is bronze, the expansion coefficient of the aluminum alloy and the zinc alloy is larger.



In the production of parts forming, stamping is a processing technology for processing large quantities of work pieces. During the stamping process, there will be many problems in the mold. Therefore, it is also one of the important factors in the whole stamping production factors, which will directly affect the production efficiency and cost. The most common problems in production include die damage, product quality defects and die grinding.
