American Precsion Products can help you save money and greatly improve quality on your compression and transfer molding programs by converting them to injection molding.
Hand load (mold) inserts are mold components that are ejected with the molded part and manually removed in order to create undercuts and create threaded features
Typically undercuts are created by side actions or core pulls that automatically retract at some point during the molding cycle. These features can be quite expensive to build and take time.
Tooling schedules all follow a typical sequence wether injection, compression or transfer molding. If the program requires further assembly or secondary operations they can increase the number of steps. These are the typical steps of our tool building programs.
There are times when it is necessary to move tooling from one molder to another. Cost considerations, quality and delivery issues can force your hand to move tooling. Changing molding vendors is always fraught with hidden perils but there ways to mitigate your risks. Successful tooling transfers take careful planning to avoid production delays and unexpected costs.
Non-Export VS Export Tooling
Non-export tooling is tooling built outside of the US that cannot be transferred from the molder/mold maker. Tooling will often be built to non-standard specifications using local steels. It will have a stated tool life. At the end of the tool life a new tool will have to be purchased in order to produce more parts.

A family mold is a mold which combines different part numbers into the same mold base. There can be multiple cavities of the different part numbers. Family molds can often have a mold building cost advantage over molds dedicated to a single part number. The are applicable to all our molding processes: Injection Molding,
