What's the pressure and speed of melt press in injection molding machine?

Answer:

Sol pressure: commonly known as back pressure, refers to the back of the screw when the pressure carried. In the process of melting and plasticizing of plastics, the melt moves to the front of the cylinder (metering chamber), and more and more, gradually forming a pressure to push the screw back. In order to prevent the screw from backing too fast and to ensure uniform compaction of the melt, it is necessary to provide an opposite direction of pressure to the screw, which is the reverse pressure that prevents the screw from retreating. Back pressure is also known as plasticizing pressure, and its control is achieved by adjusting the oil return valve of the injection cylinder. Pre injection plasticizing screw injection molding machine is equipped with the rear end of the oil cylinder back pressure valve, regulating screw back when the injection cylinder oil cylinder speed, to maintain a certain pressure; shift speed screw motor after (resistance) is composed of AC servo valve control.Sol speed: injection molding machine in the gum into the screw drive, the screw moving speed, that is, the plastic into the screw speed.
The driving force of the screw is the pressure of the sol, and the speed of the screw is controlled by the speed of the sol;
Sol pressure: commonly known as back pressure, refers to the back of the screw when the pressure carried. Sol speed: injection molding machine in the gum into the screw drive, the screw moving speed, that is, the plastic into the screw speed.The new technology adopts the switched reluctance servo motor to drive the hydraulic pump and drive screw to realize the valveless servo hydraulic system with high efficiency and energy saving and high reliability.
