Pressure adjustment during injection molding
May 26, 2022
Whether it is a hydraulic or electric injection machine, all the movements in the injection molding process will generate pressure. Appropriate control of the required pressure can produce a finished product of reasonable quality.
Pressure regulation and measurement system On hydraulic injection presses, all movements are performed by the oil circuit responsible for:
1. The screw rotation in the plasticization phase (can determine and even control the back pressure).
2, slide channel (nozzle mouth near the nozzle bush).
3. Axial movement of the injection screw during injection and holding.
4. Close the substrate to the shot rod until the toggle is fully extended or the piston's closing stroke has been completed. 5. Start the ejector table of the ejector pin to eject the part.
