Single Screw 25mm 20kg/H Ppr Pipe Extrusion Machine

The core patents of Single screw extruder:

A1: Extruder screw It is a key component of plastic transportation and plasticization. Due to its rotation, the plastic is pushed forward to achieve compaction, melting and mixing. The thread is composed of different functional parts to achieve better conveying, compaction, mixing, plasticizing effect and high output. The screw material is made of high-quality nitrided steel (38CrMoALA), and is nitrided and finely ground. It has high corrosion resistance and wear resistance, and has a long service life. A2: Extruder head flange joint It is part of the joint and barrel and is heated by a heating ring to prevent the molten plastic from cooling. A3: Extruder drive system The transmission system will evenly rotate the screw with the necessary torque under the selected process conditions to complete the plasticization and transportation of the plastic to the screw. In order to meet the production requirements of various specifications of plastic products, the screw should have different speeds. The machine uses a variable frequency motor to directly drive the gearbox through the coupling, and uses a speed regulator to achieve speed regulation, so that the screw speed can be smoothly adjusted within the speed range, and the screw speed can be directly adjusted. It is read by the tachometer on the control panel. It can also be read directly on the governor.
