Plastic Pipe Extrusion Machine For PVC Silent Pipe / UPVC Hollow Silent Pipe

PVC Silent pipe extrusion production line

Technical data:

This line is mainly used for producing PVC silent pipes with solid pipe wall and hollow pipe wall. With diferent mold, the inner line could be straight or spiral.  By changing the mold, it can also produce common PVC water pipes. This PVC silent pipes are mainly use for the aspects of constructional plumbing.  

The process flow of this line as blow:

PVC powder + additive --- mixing---material feeder---twin screw extruder---mould and calibrator---vacuum forming machine---haul-off machine---cutting machine---discharge rack. 

The screw of the extruder could be designed as lower filler screw and high filler screw. With advanced design, it provide powerful safeguard for the PVC plasticization. There is degassing system for the screw and barrle, which will ensure the quality of final PVC silent pipes. The motor adopt Siemens standard motor, ABB inverter, Siemens PLC control system.

The tank body adopt two chamber structure: the vacuum calibration and cooling parts. Both of them adopt stainless steel 304# . The excellent vacuum system ensures the precise sizing for pipes; spraying cooling will improves the cooling efficiency; Auto water temperature control system make the machine more intelligent.

The haul-off machine of this PVC pipe line will adopt two or three caterpillars, and the compact mode of haul-off frame adopt pneumatic and gear motor. With meter code, it can count the pipe length during the production. To make inner line spiral, this haul-off machine could be designed as rotate type. 

Cutting system adopt PLC control and it could be no-dust cutter and planetary cutter. There is dust-collecting system ensures clean working environment.

The pipe belling machine can make pipe with different belling shape, such as "U" type, "R" type etc. We can also design pipe belling machine with auto rubber ring feeding system.
