Question:

How to control injection speed of injection molding machine

It's the principle of the machine. The pressure is controlled by the oil pressure. How does that speed reach the set value, such as a set of 60 pressure, and the speed is 45, then how does the machine reach the set 45?

Answer:

When your speed is set to 45, the controller of hydraulic system flow control valve (or swash plate or servo motor speed / current) outputs a voltage value corresponding to the 45 (current or voltage) signal, controls the hydraulic system pump flow, the greater the flow, the faster the. Set each speed into a corresponding control signal value, control the size of the system traffic, they are linear relationship. The greater the speed you set, the greater the flow will be. So the injection speed is up to this point. (flow is the volume of liquid output per unit time of the pump)If you have any questions, please feel free to ask. I hope I can help you!
The size of the output flow of the PQ valve can be adjusted by the magnitude of the current

It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity. According to the arrangement of injection device and mould locking device, they can be divided into vertical type, horizontal type and vertical horizontal compound type.
