Complete Process Flow of Plastic Pipe Extrusion Process

Plastic pipe extrusion process is a thermoplastic processing method that continuously extrudes heated and molten plastic into pipes using an extruder. The core process consists of four main stages: raw material plasticization, die forming, cooling and solidification, and traction cutting. Continuous and stable production can be achieved throughout the entire process.

Complete Process Flow:

1. Raw Material Preparation and Plasticization: PE, PVC, and other resins are mixed with corresponding additives according to the formula. After drying and dehydration, the mixture is fed into the extruder barrel, where it melts into a homogeneous fluid under heating and screw shearing.

2. Die Forming: The molten material is pushed by the screw through the annular flow channel of the die head, forming a tubular blank. The die directly determines the outer diameter and wall thickness accuracy of the pipe.

3. Cooling and Solidification: The extruded pipe blank immediately enters a vacuum sizing sleeve and cooling water tank. Vacuum adsorption maintains its shape stability, and rapid cooling and solidification ensure the roundness of the pipe.

4. Traction Cutting and Packaging: The cooled pipe is pulled out at a uniform speed by a traction machine and automatically cut to the set length. After passing dimensional and appearance inspections, it is labeled and packaged.
