UPVC

The PVC Injection Molding Machine. Purpose-Built.

PVC and UPVC resins are corrosive, temperature-sensitive, and unforgiving to standard equipment. The JETMASTER-UPVC is a dedicated PVC injection molding machine built from the ground up to handle them. Specialty bi-metallic anti-corrosive screw and barrel, fan-cooled barrel with convection cooling tunnels, and anti-corrosive nozzle with interior plating. Every component that contacts PVC is designed for long service life. 

160 to 650 tonnes, 2 sets of core pulls as standard, extra-wide doors sized for pipe fitting molds, stainless steel hopper and chute, and servo-hydraulic drive. A pipe fitting injection molding machine ready for production from day one.

FAQ

01 Why Choose A Dedicated PVC Injection Molding Machine Over A Standard Machine?

A standard injection molding machine with a PVC screw option addresses plasticising, but PVC processing attacks the entire machine.

The JETMASTER-UPVC is a dedicated PVC injection molding machine engineered from the ground up for chlorine-containing resins: anti-corrosive nozzle with interior plating, stainless steel hopper and chute, fan-cooled barrel for precise temperature control, corrosion-resistant coatings throughout, and extra-wide doors designed for pipe fitting molds. These are not features you can retrofit to a general-purpose machine.

The JETMASTER-UPVC pipe fitting injection molding machine produces the full range of UPVC and PVC fittings: elbows, tees, reducers, couplings, valves, and custom fittings from 160 to 650 tonnes.

It also handles power switches, sockets, building components, and metallic tool housings. Chen Hsong provides specialized configurations for non-standard PVC applications on request.

The JETMASTER-UPVC PVC injection molding machine is available from 160 to 650 tonnes (JM160 through JM650). This range covers everything from small household pipe fittings and electrical components to large industrial PVC pipe fittings and infrastructure products.

PVC is highly sensitive to overheating, which causes material degradation and releases corrosive gases. The JETMASTER-UPVC uses fan cooling with a convection-type cooling tunnel design instead of conventional water cooling. This provides stable, uniform temperature control across the entire barrel length, preventing hot spots that degrade PVC quality. 

Chen Hsong provides installation, training, maintenance, and technical support through more than 120 service locations worldwide. Replacement UPVC-specific components including bi-metallic screws, barrels, and anti-corrosive nozzles are stocked for long-term availability.
