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.
