Insert Molding

Premium provides insert molding service, which is a process that requires an insert to be pre-placed in the mold for injected plastic to flow around.


Plastic insert molding is ideal for improving the strength and reliability of a component by eliminating the need for secondary operations such as soldering, connectors, and adhesives. Insert molding can be accomplished through manual insert loading, the general cost-effective way to approach low volume applications or extremely complex part geometries, but automatic insert molding is a better choice for part consistency. It reduces human error, improves efficiencies, and ensures optimal cycle times.

How Does Insert Molding Work?

Insert molding can be processed both vertical and horizontal molding machines:

2. Molten plastic is injected into the mold.

3. The mold opens once cooling and the components are removed.

4. Components are separated from the sprue and inspected.
