Custom Manufactured PVC Pipe Fitting Mold for the Plumbing Industry

The custom manufactured mold pictured to the left is used to make PVC pipe fittings for the plumbing industry. A client contracted Colonial Machine to fabricate this mold based on a customer-supplied 3D geometry. Our skilled technicians first employed various horizontal and vertical CNC milling machinery to rough machine all impression surfaces and side pockets, as well as counter bore, tap, and drill waterlines to print and machine ejector pin holes. We also produced all side locks and counter pockets, and formed the horn pin clearance. Finally, we finish machined all impression surfaces.

After completion, the overall mold measured 56” x 35”, weighed approximately 10,000 lbs., and possessed various stainless steel cavities and cores heat treated for better wear. The mold produced a 4” diameter 90 degree elbow that satisfied both customer and industry quality standards. Over the years Colonial Machine has produced over 100 molds for a variety of fitting for this customer with this mold being delivered to their facility in Texas easily within their requested delivery time of 10-12 weeks.
