Plastic Injection Molding of CPVC Pipe for an Electronic Metering Pump Application

A customer in Boston, Massachusetts invited Royal Plastics, Inc to mold a CPVC part to be used in an electronic metering pump application. Well-versed in all things that involve injection molding and welding, we performed our assignment with our customary skill and gusto.

Through the process of injection molding, we molded a part in CPVC that previously was a 2 part assembly. As testament to our precision, tightest tolerances ranged a mere +/- .005″. We followed the customer-supplied print with an exactitude that is prized among our various clients, but is simply part of the job for a company like ours.
