50-160mm High Output Plastic Extruders PVC Pipe Line Plastic
Extrusion Machine
1. Feeding: The compound is fed into the extruder hopper, where it
is gravity-fed into the extruder barrel.
2. Melting and Homogenization: Inside the extruder barrel, the
compound is heated and melted by the friction generated by the
rotation of a screw. The screw also helps in homogenizing the
molten material.
3. Extrusion: The molten PVC compound is forced through a die with
the desired shape and dimensions. The die shapes the material into
a continuous pipe.
4. Cooling and Sizing: The extruded pipe is cooled using a water
bath or air cooling system. Sizing tools are used to control the
dimensions and shape of the pipe.
5. Cutting and Stacking: Once the pipe has cooled and solidified,
it is cut into desired lengths and stacked for further processing
or packaging.
The PVC pipe extrusion machine offers several advantages:
1. High Efficiency: The extrusion process allows for continuous
production, resulting in high output rates and efficient use of
resources.
2. Versatility: PVC pipe extrusion machines can produce pipes of
various diameters, wall thicknesses, and lengths, making them
suitable for a wide range of applications.
3. Cost-Effectiveness: PVC pipes produced by extrusion are
generally more cost-effective compared to other pipe manufacturing
methods. The process requires fewer raw materials and has lower
labor costs.
4. Customization: The extrusion process can accommodate different
formulations and additives, allowing for customization of PVC pipes
with specific properties, such as UV resistance or fire retardancy.
