Injection Molding

Injection molding is a method to obtain molded products by injecting molten plastic material into a tool under high pressure, and then cooling and solidifying the product in a highly repeatable process.

Injection molding is used to produce tight tolerance, high quality, high volume components. Our injection molding capabilities enable us to produce a wide variety of functional parts in various shapes, sizes and wall thicknesses.

Insert Molding
& Over Molding

Centennial Plastic has strong technical capabilities and extensive experience in precision insert molding and over molding.

The process begins with our client sending us a shipment of metal inserts or other prefabricated parts that require a plastic over molded component.

This part is then inserted into the mold cavity and over molded with a plastic feature.

The completed assembly is produced through a single process, which reduces manufacturing time, assembly time, and creates a high quality product. We are proud of the integrated relationships we develop through this process, which involves our clients also becoming our suppliers.
