Common Pipe Extrusion Machine

Most manufacturers often change component suppliers or take much time to order spare parts. They adopt outdated technical specification for extrusion machine without reducing energy consumption or improve production capacity. Many our customers who used these old machines said although the price of the extrusion pipe machine is very low, they cannot be used for a long time. Also, some extruder line suppliers can't offer reliable service, because they don't have enough resource to support it.

Factors Affecting Extrusion Machine Production

Screw structure

Different screw structures directly affect the plasticization of plastic raw materials and the quality and output of final products.

Transmission system

Provide the screw with appropriate speed range, stable speed and uniform torque, and be able to withstand the huge screw axial force generated in the production process.

Electronic control system

Great electronic control system can ensure smooth production and affects performance of heating, cooling and pressure system.

Heating and Cooling system

Accurate and uniform heating and cooling system play an important role in screw extrusion and calibration, then affects thickness and surface of final products.

What is Pipe Extrusion Process?

There are six steps during pipe extrusion process. Firstly, mix material, then extrusion part, pipe calibration, cooling, haul off, cutting. The following are the causes and solutions of some problems during pipe production process.

Corrugation on pipe surface

Insufficient cooling: It is necessary to increase the water inlet of the sizing sleeve or increase the spacing between the die and the sizing sleeve.

Vibration

The size of the sealing ring of the vacuum box is too small. Replace the sealing ring or appropriately reduce the vacuum of the first vacuum box and increase the vacuum of the second vacuum box.

Pit on surface

Raw materials are wet, and the water volume of sizing sleeve is uneven.

Nonuniform wall thickness

Loose die or core die bolts, improper adjustment of die clearance, uneven die or core die temperature, resulting in inconsistent material flow, wrong sizing sleeve and die center, screw diverter shuttle or screen blockage: tighten the bolts or adjust the die clearance, check the heating ring and temperature sensor, adjust the die and sizing sleeve center, and clean the screen.
