Flexible Plastic PE PPR Electric Water Pipe Extruder Machine

Plastic Flexible PE Electric Water Tube Hose Pipe Machine Line PPR Water Pipe Production Machinery

The production line for PP (polypropylene) and PE (polyethylene) pipe extrusion typically consists of several interconnected components to facilitate the efficient and continuous manufacturing of pipes. Here is an overview of the key components and the overall process involved in a PP PE pipe extrusion machine production line:
1. Extruder:
The raw material is fed into the extruder, where it undergoes melting and plasticization. The extruder is equipped with a screw mechanism that conveys, melts, and homogenizes the polymer. The extruder can be a single-screw or twin-screw design, depending on the requirements of the application.
2. Screen Changer:
A screen changer is employed to remove impurities or contaminants from the molten polymer, ensuring a clean and uniform material flow.
3. Melt Pump:
In some extrusion lines, a melt pump may be used to provide a consistent flow of molten polymer, enhancing the control and stability of the extrusion process.
4. Die Head:
The molten polymer passes through a die head, which shapes and forms the pipe. The design of the die head determines the size, shape, and specifications of the extruded pipe.
5. Vacuum Calibration Tank:
The extruded pipe enters a vacuum calibration tank, where it is cooled and shaped to meet the desired dimensions. The vacuum calibration tank helps ensure uniformity and accuracy in the pipe's dimensions.
6. Haul-off Unit:
A haul-off unit, also known as a puller, grips the pipe and pulls it through the extrusion line at a controlled speed. This process ensures that the pipe is consistently formed and maintains the desired dimensions.
7. Cutter:
After leaving the haul-off unit, the extruded pipe passes through a cutting device, which cuts the pipe into the specified lengths. The cutter may use a saw blade or another cutting mechanism.
8. Coiler:
The coiler winds the finished pipes onto spools or coils. This component facilitates easy handling, storage, and transportation of the final product.
The specific configuration of the production line may vary based on the intended application, the size and type of pipes to be produced, and the characteristics of the PP and PE materials used. Manufacturers often customize extrusion lines to meet the unique requirements of their production processes.
