Custom Plastic Injection Molding Service 

SEAL-RP is your parts manufacturing partner and focuses on manufacturing high-precision plastic molds and injection molding. Our custom plastic injection molding service provides custom prototypes and end-use production parts with a short lead time.


What is Injection Molding Service?

The plastic injection molding process requires an injection molding machine, raw plastic material, and a machined mold.

The raw plastic material is first melted in the injection unit and is then injected into the mold—most often machined from steel or aluminum—where it cools and solidifies into the final plastic part.

A professional plastic injection molding manufacturer like SEAL-RP will provide complete custom plastic injection molding service for every client, including free part design advice, help to select a plastic material, and target cost planning for your tooling and production.



How Does Injection Moulding Work?

Material granules for the part is fed via a hopper into a heated barrel, melted using heater bands and the frictional action of a reciprocating screw barrel.

The plastic is then injection through a nozzle into a mould cavity where it cools and hardens to the configuration of the cavity.

The mould tool is mounted on a moveable platen – when the part has solidified, the platen opens and the part is ejected out using ejector pins.
