Injection mold manufacturing technology

Steps in Injection Mold Manufacturing

In modern industrial production, injection molding technology has become one of the most important manufacturing methods. And injection molding technology is based on the injection mold. The manufacturing process of injection molds is very complex and requires multiple steps.

This article will introduce the steps of injection mold manufacturing, hope to be able to help readers.

First, mold design

The first step of mold manufacturing is design. In the mold design, the first need according to the shape of the injection molded part and the requirements to determine the type of mold. Then, according to the shape and size of the injection molded parts, as well as the type and nature of the injection molding material required, the mold structure design. Finally, material selection and heat treatment design to ensure the quality and performance of the mold.

Second, CNC machining

CNC machining is a very important part of mold manufacturing. CNC machining can realize high-precision, high-efficiency rate of parts manufacturing, especially important for mold manufacturing. In CNC machining, usually using milling, cutting, drilling and other processing methods to achieve the mold processing and manufacturing.

Third, precision grinding

Precision grinding is one of the key steps in mold manufacturing. Precision grinding can help grind the various parts of the mold and die

And ensure its dimensional accuracy and surface roughness, but also can increase its sealing performance and wear resistance, improve the service life of the mold.

Fourth, electric discharge machining

EDM is a highly efficient non-contact processing methods, which can be realized through the discharge phenomenon of metal melting and cutting, for mold manufacturing is also a good idea.

Melting and cutting of metal through the discharge phenomenon, for mold manufacturing is also very important. Usually in the mold inner and outer contour and dimensional accuracy requirements of the high part of the EDM. EDM can improve the precision and surface finish of the mold, and reduce manufacturing and processing costs.

V. Assembly and commissioning

After the mold manufacturing is completed, it needs to be assembled and debugged. The assembly process needs to check the various parts of the mold to ensure its correctness and tightness.

parts of the mold to ensure its correctness and tightness. In the debugging process, it is necessary to carry out injection molding tests to simulate the production environment and test the performance and reliability of the mold. Through appropriate adjustments and precise tests, the stable operation of the mold can be ensured.

Summarize

Injection mold manufacturing is a very complex process, which needs to be completed through a number of steps. From mold design

design to CNC machining, precision grinding, EDM and assembly debugging and other aspects, all need to ensure the accuracy and efficiency of manufacturing. Only through strict inspection and testing can the quality and performance of injection molds be guaranteed.
