Injection mold inserts require very high precision and generally need to be customized according to the requirements, which can be direction, circle or other shapes. Injection mold inserts refer to irregular mold fittings used to set in a mold and serve to hold and fill the space between the formwork.

Classification of injection mold inserts

The types of injection mold inserts are mainly divided into insert needle, insert block, insert column, insert ring and so on. The commonly used materials are SKD61, SKH51, ASP23, SKD11 and so on. The hardness generally reaches above 50HRC and the standard accuracy is ±0.01mm.


The role of injection mold inserts

1. Save injection mold manufacturing materials. If there is a higher place of the front or back die, the height of the injection mold can be reduced by making inserts, so as to save the manufacturing materials of the injection mold and save the cost.

2. Convenient for subsequent mold modification. Where the injection mold often needs to be modified, the insert can be removed to facilitate the subsequent modification of the mold. Because you only need to change the insert, it is convenient, quick and cost saving.

3. Repair the mold and increase the strength of injection mold. When there is a small area of insertion on the molded parts such as the mold or slider, the insertion part can be disassembled into an insert to repair the mold and increase the strength of the injection mold.

4. Shorten the delivery time of injection mold

When there are deep bone positions in the cavity to be processed, it can be disassembled into inserts for convenient processing, which can greatly shorten the processing time of injection mold.

In fact, the biggest disadvantage of the insert is to reduce the strength of the injection mold itself, but the insert can use different raw materials and separately increase the strength of the thin parts. In order to facilitate maintenance, it is advisable to carefully design the mold inserts during the mold design stage. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the service life is long, the rapid mass production and the finished product quality is excellent!
