High Precision CNC Milling Parts Polished Core Insert for Cosmetics Injection Mold Components

The Application Of Core Insert

Core Insert molding is the process of inserting a component into a mold prior to the injection molding process. note that the injection molding process is still the same, there is just something being molded into the part. some of the key benefits of using Core inserts on molded parts include:

1. Improved strength

2. A strong and reliable attachment point for assemblies (Core Inserts)

3. More cost effective when compared to other Core inserts Production processes

4. No significant mold changes required

If this part were not insert molded, an operator would need to manually apply each insert to the plastic part after the molding process. the inserts could be pressed, heat staked, or ultrasonically applied to the part. the end result is the same (mostly) as it is with insert molding; however, there are several disadvantages of using the manual method:

1. There is the added cost of secondary equipment and fixtures
2. Manual labor is required
3. The process is difficult to scale with high order quantities
4. Plastic can fatigue and melt at the surface leaving noticeable imperfections
5. Manual processes are likely not as strong and consistent as insert molding

In addition to the above disadvantages, the other methods also limit the types of components that can be used. for example, if you were adding an electrical connector or other more complicated features, heat staking and pressing might not be viable options. in the next section, we’ll look at the various types of inserts available for insert molding.
