Advanced Liquid Package Solution
ü When checking the high-voltage components in the machine, if it is not necessary, the main power supply should not be turned on.
ü When changing the mold, it is impossible to make the cooling water flow into the control box.
ü Check whether the temperature in the control box is too high to affect the normal operation of the electronic board.
ü When replacing the relay, the specified voltage relay should be used.
ü The pressure temperature of the injection molding machine should be kept between 30-50 degrees Celsius. If the oil temperature exceeds 60 degrees Celsius, the following problems will occur: pressure oil deteriorates due to oxidation.
ü Oil pump damage, oil leakage and pressure drop due to reduced pressure oil viscosity and the working efficiency of the decompression oil switch.Accelerates the speed of oil seal aging.
ü Prevent the cooling water from leaking into the oil cylinder, and pay special attention to check whether there is water leakage inside the oil cooler. Every 6 months or so, the oil cooler should be removed and cleaned inside.
ü The pressure oil must be replaced every 3000-4000 hours of operation of the injection molding machine. When replacing the pressure oil, do not mix the old and new oil, and at the same time, the oil screen in the oil cylinder should be turned off for cleaning.
ü The oil switch fails because the valve core is blocked by foreign objects. The valve core should be removed from the oil switch and cleaned with diesel oil or kerosene (or immersed in clean pressure oil for cleaning), and then use compressed air to remove foreign objects. Unless it is confirmed that the oil switch is blocked by foreign objects and causes the injection molding machine to malfunction, do not remove the oil switch casually.
ü The working life of the hinge of the clamping part is very long, but each movable part should be properly lubricated, otherwise the hinge will wear and reduce the life.
ü Keep the four Corinthian pillars clean.
ü Keep the sliding feet and rails of the moving template clean and lubricated.
ü Avoid using mold clamping close to or exceeding the working pressure.
ü When adjusting the mold, the fast mold clamping speed cannot be used.
ü Control the stroke position of the clamping action to the most appropriate position to reduce the impact on the machine during clamping.
ü Keep the guide rod of the injection table lubricated and clean.
ü Keep the surface of the injection table clean and dry.
ü Except plastics, pigments and additives, do not put anything into the hopper. If you use the return material, you must add a hopper magnetic frame to the hopper to prevent metal fragments from entering the melt tube.
ü When the glue barrel does not reach the preset temperature, do not start the glue melting motor, and do not use the reverse cable (releasing) action to avoid damage to the rotating system components.
ü Before using special plastics, you should consult the plastics business, what kind of injection screw is more suitable for this kind of plastics.
ü Use the correct plastic replacement and cleaning methods provided by the plastics manufacturer.
ü Periodically check each part of the injection table, tighten the loose parts, and ensure that the two injection cylinders are installed in a balanced manner, so as to avoid damage to the oil seal of the injection cylinder, resulting in oil leakage and wear of the cylinder pump core.
ü Regularly drain the grease of the beer bell combination of the hydraulic motor and replace it with new grease.
ü When the melt temperature is normal and the melt black spots or discoloration constantly appear, check whether the glue ring and glue meson of the injection screw are damaged.
