Mold inserts are widely used in injection mold processing, mainly in front molds, back molds, sliders and inclined tops. So why do you need inserts for injection mold processing, and what is the purpose of injection mold processing inserts?


1. Save injection mold manufacturing materials

As we all know, the injection mold is to fix the material with a relatively regular block steel with a fixed shape, but the material of the front and rear mold is determined by the height, whether it is the front mold or the rear mold, if one place is higher than other places, you can make 2. Inserts to 2. Reduce the height of the mold.

It is convenient to change the injection mold where the injection mold is often modified, it can be removed to make inserts, and only the inserts need to be changed when the mold is changed in the future, and even a few more inserts can be replaced when the mold is opened, so that it is convenient to modify the mold.

3. It is conducive to the exhaust of injection molds

The venting of the injection molding mold is very important. If the exhaust is not good, there will be trapped air in the mold cavity, especially in the relatively deep bone position, and the product is prone to bubbles or shrinkage, lack of glue, whitening or black spots and other undesirable phenomena during injection molding. Therefore, it is possible to add inserts where the mold needs to be vented, and use the mating gap of the inserts to vent them.


4. Convenient for injection mold processing

There are some deep bones in the injection mold, the cutter is difficult to process, although it can be processed by electric spark, but the EDM processing speed is slow, and the processing efficiency is not high, so it is generally chosen to do inserts, which reduces the difficulty of processing, and is also convenient for exhaust In addition, it is deep bone type mold saving, because it is very inconvenient to save the mold in the place where the mold must be saved, but it is much more convenient to open the inserts in these places and disassemble the province.

5. Extend the service life of the injection mold

Generally speaking, the injection mold needs to design the insert, often the mold is easy to damage, once the insert is damaged, it can be replaced, so as to extend the service life of the injection mold, save time and money.


As a professional mold manufacturing and processing enterprise, we should ensure efficient production and provide customers with better service and better products. If you have open injection molding needs, please contact us and we will be happy to serve you.
