Pipe bending is an essential manufacturing process across industries such as automotive, HVAC, construction, shipbuilding, furniture, fitness equipment, and metal fabrication. As factories expand capacity and move toward automation, choosing the right bending machine becomes a key strategic decision.

Accurate pipe bending is one of the most critical processes in plastic pipe manufacturing, impacting product consistency, structural strength, and downstream assembly.

Bending plastic pipes is a core process in plumbing, drainage, industrial piping, and infrastructure projects. While fittings such as elbows and joints are widely used, precision pipe bending machines allow contractors and manufacturers to form smooth curves without increasing joint counts, reducing leakage points, and improving flow efficiency.

A belling machine (also called a socketing or end-forming machine) heats the end of a thermoplastic pipe—typically PVC, CPVC, PP, or PE—then reshapes it over a mandrel to create a socket (bell) that accepts another pipe’s spigot end. The bell may be smooth for solvent-cement joints or grooved to seat a rubber ring (elastomeric gasket).
