PVC Pipe Extruder Processes

 

General Information:

 

Plastic extrusion pipe, hose, cable, profile etc. It is a manufacturing method used in the production of plastic materials. The machine used in extrusion is very similar to the injection machine. A motor rotates the screw in a sleeve covered with a heater, causing the plastic granules to melt under temperature and pressure. The molten plastic takes shape along the mold and enters the liquid in the form of a long channel to cool. The shape of the mold also determines the shape of the duct. After cooling, it takes shape as solidified. The channel can be marked and then cut at equal intervals. Parts are packed or stocked by running over the rollers. The shapes that will come out of the extrusion can be T-Section, U-Section, Square-Section, I-Section, L-Section and Circular Sections. Fiber optic cable can be given as an example of products produced by extrusion.

 

 

 

General Parts:

 

It consists of raw material feeding hopper, extruder driven motor, gear reducer box, screw and barrel, heaters, cooling fan form molds, hopper and control cabinet.

 

 

 

Working Principle:

 

A wide variety of methods have been developed for producing shaped objects from granules or powdered plastics. An extruder is often used to shape thermoplastics; plastic tubes, pipes, rods are produced.

 

 

 

What is a Melt Pressure Sensor?

 

Melt Pressure Sensor is an instrument used to measure the pressure and temperature of melted liquids (optional) in processes where plastic raw materials can reach high temperatures.

 

 

 

Why is a Melt Pressure Sensor Necessary?

 

Almost all extruders use at least one melt pressure transducer because it is desirable for melt pressure/temperature control to improve the quality of the extrusion process.
