Injection molding machine downtime

When the production is finished or the quality of the injection molding product fails, the injection molding machine needs a temporary shutdown or a long shutdown. How to do a shutdown is not only related to the quality of the next molding and the loss of raw materials, but also affects the service life of the screw and barrel.

one. Temporary shutdown happens just before the molding is completed or before the temporary stop. The material of the cartridge type is ejected empty, and then the appropriate amount of cleaning material is added to clean the cartridge. Press the heating switch to turn off the heating of the cartridge. Close the hopper bezel. If it is a temporary short-term shutdown, do not turn off the barrel heater and reduce the heating temperature by 100 to 150 degrees per segment.

two. Shutdown Shutdown When the material is used up or the required number of products has been produced, it must be turned off. If the injection molding machine is equipped with a temperature regulator for nozzle temperature adjustment, turn the regulator button to 0 to disconnect the regulator. This is not only for the purpose of heating the feed tube in the shortest possible time during the next injection molding operation. In order to prevent the molten resin from remaining in the barrel, the remaining material in the heating barrel should be completely removed (by air injection several times), then a suitable amount of cleaning material is added to clean the barrel, and finally the screw is stopped at the forefront position. In the manual state, perform mold clamping (but do not enter high-pressure mold clamping), and return the injection block and the screw to the stop position. Turn off the oil pump motor, pay attention to the total Power Supply of the press
