Pipe Fitting Types Made with Injection Molding

The Versatility of Molded Plastic Fittings

Injection molding is a dominant manufacturing process for a vast range of plastic pipe fittings used in plumbing, irrigation, electrical conduit, and industrial fluid handling systems. A pipe fitting mold is a precision tool designed to mass-produce these components with the consistency, dimensional accuracy, and pressure integrity required for reliable system performance. The types of fittings produced span simple connectors to complex multi-port assemblies.

Basic Connection and Directional Fittings

This category includes the most common, high-volume components. A pipe fitting mold is used to produce:

Couplings and Connectors: For joining two pipes of the same diameter in a straight line.

Elbows (90-degree, 45-degree): For changing the direction of a pipeline.

Tees (Equal, Reducing): For creating a branch line from a main run.

Reducers and Bushings: For connecting pipes of different diameters.

These fittings form the essential building blocks of any piped system and are produced in enormous quantities using multi-cavity molds.
