POK pipe extrusion equipment process requirements

The process requirements of POK pipe extrusion equipment usually include the following aspects:

Extruder selection: The selection of the extruder should take into account the diameter and wall thickness requirements of the produced pipe. Usually, it is necessary to select an extruder that can provide sufficient extrusion pressure and stable extrusion speed.

Raw material selection: Select suitable raw materials, generally plastic resins such as polyethylene, polyvinyl chloride, and polypropylene. Select the appropriate raw material grade and formula according to the purpose and requirements of the pipe.

Extrusion die design: The design of the extrusion die has a great influence on the molding effect and performance of the pipe. It is necessary to ensure that the die design is reasonable and can extrude the pipe evenly to ensure the uniformity of wall thickness and appearance quality.

Extrusion process parameters: including the setting of parameters such as extrusion temperature, extrusion pressure, and extrusion speed. These parameters need to be determined according to the characteristics of the raw materials used and the specifications of the pipe to ensure the stability of the extrusion process and product quality.

Cooling system: Ensure that the extruded pipe can be quickly cooled and solidified, usually using a water cooling system. The efficiency and method of cooling directly affect the physical properties and appearance quality of the pipe.

Online detection and control: It is necessary to equip the corresponding online detection equipment and control system to monitor the key parameters of the pipe in real time, such as diameter, wall thickness, tensile performance, etc., and adjust the extrusion process parameters in time to ensure that the product meets the standard requirements.

Subsequent processing: The extruded pipe may need to be cut, packaged, inspected, etc. to ensure the quality and factory standards of the final product.
