Failure analysis and troubleshooting of screw not advancing in position during injection
(1) The injection pressure is too low, the injection pressure should be increased appropriately;
(2) The amount of feed is too much, so the amount of feed should be appropriately reduced;
(3) If the nozzle temperature is not properly controlled, the nozzle temperature should be adjusted appropriately;
(4) The temperature of the barrel of the injection machine is improperly controlled, and the temperature of the barrel of the injection machine should be adjusted appropriately;
(5) There is a material pad at the front end of the barrel of the injection machine, and the nozzle should be removed to remove the material pad;
(6) If there is stagnant material in the barrel of the injection molding machine, the stagnant material in the barrel of the injection machine should be removed.
Failure analysis and troubleshooting method of injection molding machine screw not retreating?
(1) If the powder in the hopper is "bridging", a screw feeder should be used to improve the feeding condition;
(2) The temperature of the rear barrel is too high, so the temperature of the rear barrel should be appropriately lowered;
(3) The screw roughness is relatively high, so the screw roughness should be appropriately reduced.
Analysis and troubleshooting of screw wear failure of injection machine
(1) The screw speed is too high, the screw speed should be appropriately reduced;
(2) The pre-plastic pressure is too high, and the pre-plastic pressure should be appropriately reduced;
(3) The temperature of the barrel is too low, so the barrel temperature should be appropriately increased;
(4) The amount of lubricant in the raw materials is insufficient, and the raw materials with more lubricant content should be selected.
