Analysis on the Forming Quality of PVC Double Wall Corrugated Pipe Produced by Plastic Extruder

Plastic extruder will inevitably have some quality problems in the production of polyvinyl chloride (PVC) double wall corrugated pipe, in addition to the problems of equipment itself, there are still very cases of quality problems. We can ignore the problems caused by equipment, because generally, t......

Principle and application scope of single screw extruder

In most extruders, the screw speed is changed by adjusting the motor speed. The drive motor usually rotates at a full speed of about 1750rpm, which is too fast for an extrusion screw. If it rotates at such a fast speed, too much friction heat will be generated, and the uniform and well stirred melt ......

What is the function of the barrel? What are the characteristics of the structure?haracteristics of the structure?

The barrel includes a screw, which rotates in the barrel. When the screw rotates and the thread is pushed, the heat is transmitted to the material by heating outside the barrel. In addition, the volume of the thread is gradually reduced, so that the material is evenly mixed and plasticized into a mo......

Calibration sleeve and its function

The calibration sleeve is a component that assists the cooling and shaping of plastic pipes in the extrusion production of plastic pipes. It is installed at the front end of the vacuum calibration machine. After the pipe comes out of the mold, it enters the vacuum tank and spray cooling tank for fur......

Maintenance of Single Screw Extruder

The maintenance of the extruder is divided into routine maintenance and regular maintenance: routine maintenance is a regular routine work, usually completed during start-up. The key is to clean the machine, lubricate the moving parts, fasten the loose threaded parts, and timely check and adjust the......

PVC Pipe & PVC Pipe Extrusion Line

PVC Pipe has good tensile and compressive strength, but its flexibility is better than other plastic pipe, excellent corrosion resistance, the cheapest price in all kinds of plastic pipe, but low temperature brittle adhesive, rubber ring socket flange connection, threaded connection for residential ......
