In 1972, Colonial Engineering began molding Sch 40/80 PVC & CPVC pipe-fittings. In 1984, we added plastic ball valves, butterfly valves and check valves to expand our capabilities in the industrial PVF, process piping, water treatment, pool/spa, commercial plumbing, and irrigation markets. Colonial entered the Custom injection-molding business in 1985, building on the expertise gained from molding proprietary products in the valve and pipe-fitting market.
Experience working with CPVC, PVC, PP, ABS, HDPE, Noryl, and other materials has enabled us to work with a variety of industries. In addition to injection-molding, we perform secondary CNC machining operations, hot stamp and pad print, and sub-assembly. Colonial divested of our Sch 40/80 pipe-fitting product line in 2002. Since then, we have continued to grow in the custom-molding and plastic valve markets, with two production facilities in SW Michigan.
