Advanced Large diameter 400-710mm Plastic UPVC Making Machine Factory in China
Application
The belling machine is combined with pipes extrusion production to manufacture the socket end of pipes with type of “U”, “R” and "rectangular". The belling processing should be done inside the belling room with vacuum shaping inside core of belling mould and water cooling outside the pipe In order to get the precise socket.
PRODUCTION PROCESS FLOW
The first step of pipe production is the preparation of raw material. Customers can mix the PVC powder with other additives by themself. The mixture will be feeded into extruder. The material will be plasticized in the extruder and then be extruded into the mould. The material is shaped by mould and goes out with the pipe looking. The pipe extruded from the mould is hot and soft. The pipe with unstable shape will be calibrated and cooled by vacuum sleeve in the vacuum calibration tank. And then the pipe goes into the cooling tank for a further cooling. Haul off unit stands next to the cooling tank and take the pipe away from the extruder. According to the defined length, the pipe will be cut and then packed for transport.
Following ADVANTAGES are the reasons, why PVC pipe so widely applied.
Corrosion Resistant
With self-extinguishing and flame retardant;
Excellent in anti-aging character
The PVC pipe is light, easy to flaring, bonding, bending, welding.
Installation workload and Processing cost are lower than metal pipe
Good electrical properties of resistance
Recycled and Environment-friendly.
