1. Easy to modify the mold. The molds are often modified, inserts can be pre-added to the place where the mold was modified, and only inserts can be replaced when the mold is changed, or even a few extra inserts can be replaced at the time of mold opening. This makes it easy to modify the mold.
2. Is conducive to the mold exhaust. Exhaust of the mold is very important, inserts can be added where the mold needs to be vented, and the inserts can be used to exhaust.
3. Convenient mold processing. We know that it is very difficult for some deep valleys, hole positions, polishing and plastics filling and ejection in injection molds, but inserts in these places can reduce the processing difficulty.
4. Increase the life of the mold. Under normal circumstances, where molds need to be designed for inserts, they are often easily damaged. Once the inserts are damaged, they can be replaced to extend the life of the molds.
