What Is The Purpose Of Making Inserts In Injection Mold Processing?

Injection mold inserts are also called inserts, and some people call them inserts, which have different names. It refers to the mold parts used to be embedded in the core of the injection mold, which requires very high precision. So why bother to make inserts when processing injection molds?
There are mainly the following purposes:

1. Save injection mold manufacturing materials
As we all know, the fixed material of the injection mold is a relatively regular block steel with a fixed shape, but the material of the front and rear molds is determined by the height of z, whether it is the front mold or the rear mold, if a certain place is higher than other places, it can be Create inserts to reduce the height of the mold.

2. Easy to change the mold
Where the injection mold is often modified, it can be dismantled and made into inserts. When changing the mold in the future, only the inserts need to be replaced, and even a few more inserts can be replaced when the mold is opened, which is convenient for mold modification.

3. Conducive to exhausting of injection mold
Venting of injection molding molds is very important. If the exhaust is not good, trapped air will appear in the mold cavity, especially in the relatively deep bone position. During injection molding, the product is prone to bubbles or shrinkage, lack of glue, whitening or black spots and other undesirable phenomena. Therefore, inserts can be added where the mold needs to be vented, and the fitting gap of the inserts can be used for venting.

4. Convenient injection mold processing
There are some deep bones in the injection mold, and the tool is difficult to process. Although EDM can be used, the EDM processing speed is slow and the processing efficiency is not high. Therefore, inserts are generally selected to reduce the processing difficulty and facilitate exhaust. The other is deep bone type mold saving, because it is very inconvenient to save molds in the places where the mold must be saved, but it is much more convenient to open inserts in these places and disassemble them.

5. Extend the service life of the injection mold
Generally speaking, the place where the injection mold needs to design inserts is often the most vulnerable part of the mold. Once the insert is damaged, it can be replaced, thereby prolonging the service life of the injection mold.
