introduction：Melting in plastic、During plasticizing，The molten material is constantly moving towards the micro front end of the material（Metering room），And more and more，Gradually a pressure is formed to push the screw backwards。To stop the screw from backing up too fast，Make sure the melt is evenly compacted，It is necessary to provide a pressure in the opposite direction to the screw，The pressure in the opposite direction that prevents the screw from receding is called back pressure。Back pressure is also called plasticizing pressure， Its control is achieved by adjusting the return oil throttle valve of the injection cylinder，The pre-plasticized screw injection molding machine is equipped with a back pressure valve after injecting the oil cylinder，Adjust the speed at which the injection cylinder drains when the screw rotates backward，Keep the cylinder at a certain pressure（Such as
