Causes of difficulties in manufacturing and processing injection molds

by:Vowin Rapid Prototyping     2023-02-03
Mold is called the mother of industry, not only because it can make product design into reality, but more importantly, it can improve the efficiency of mold processing, reduce costs, and carry out mass replication. Especially in today's fast-paced industrialization process, the mold industry is still called a sunrise industry, full of opportunities. However, due to the high technical requirements of the injection mold industry, the stable and long-term development is inseparable from the level of sophisticated injection mold manufacturing and processing. What are the reasons for the difficulty in manufacturing and processing injection molds?

1. The structure of cavity and core is complex

Plastic parts are directly injection molded by combining cavity and core. Complicated surface processing is relatively difficult, especially the surface processing of blind holes in some cavities. In this case, if the traditional injection mold processing method is adopted, in addition to consuming more auxiliary fixtures and tools, experienced injection mold manufacturing masters are also required, and the injection mold processing cycle will also be extended.

2. High precision and appearance requirements for plastic parts

The ejector device is an important factor affecting the deformation and dimensional accuracy of plastic parts. Therefore, when designing the injection mold, the ejector point should be selected to ensure that the plastic parts are evenly released from the mold. The structural design of high-precision injection molds mostly adopts inlaid or fully assembled structures. This structure has greatly improved the processing accuracy and interchangeability of mold parts.

3. The technological process is cumbersome, and the manufacturing and processing time is tight

Most of the plastic parts are complete products composed of parts and components, so the precision requirements are very high. After the mold is made, repeated mold trials and corrections must be carried out. Therefore, the design, development and delivery cycle of injection molds are tight. Each All aspects cannot be ignored.

Shanghai Mulan Injection Mold Factory has 10 years of experience in exporting to Japan. The precision of mold life is customized according to the R&D process of exporting molds to Japan and customer requirements. The tolerance of molds in important dimensions can reach ±0.02mm, and the number of production times can be as high as 300,000 to 1 million molds.
