Failure causes: ① power supply is out of phase (Solution: check the power supply) ② auditing current limiter value is too low (solution: adjust the value of the current limiter and then press the reset button RESET) ③ pump short circuit rotor bearing damage

Cause of failure: ① computer board damage (Solution: replace or repair the computer board) ② Fuse damage (Solution: replace the fuse) ③Button switch poor contact (Solution: replace the button switch)

Cause of failure: ① Cooling water system pressure is not enough (Solution: increase the cooling water system pressure in accordance with the factory settings) ② Solenoid valve damage (solution: replace the solenoid valve) ③ pressure switch misoperation (solution: replace the pressure switch) ④Piping system blockage (Solution: check whether the media piping is blocked)

Cause of failure: ①Heating AC contactor stuck (Solution: replace the AC contactor) ② computer board heating has been output (solution: replace the computer PC board) ③ over-temperature protection switch misoperation (solution: replace the over-temperature protection switch)

Cause of failure: solenoid valve blockage or solenoid valve coil aging Solution: clean or replace the solenoid valve

Fault cause: power phase sequence error Solution: Close the total power supply of the mold temperature machine, the power line in any two power lines interchange, if still alarm, replace the reverse phase protector. For the solution to common failures of the mold temperature machine to share this, in the daily use of the process, although the mold temperature machine does not belong to the frequent need for special maintenance, but also to regularly observe and check, in order to find abnormalities in a timely manner to ensure production efficiency and product quality.

To keep the water clean cooling towers, water towers and keep the air circulating around the low temperature, to avoid any debris into the towers, reduce cooling efficiency.

Reduce mold "inverted sweat" generation, before stopping plastic machine, die of cold water first subsidiary towing off, or turn off the chiller, which makes the cavity water temperature rises, so that the mold will not rust.

Such as chiller has been used for more than three months, the high and low pressure are often faulty, or cooling capacity decreases, please arrange for staff to clean the heat gun (high pressure gauge pressure than 20MP, please clean the heat gun, or check whether the switch is open to do Shuihou ).

What cleaning chiller? Cooling water systems: Recommended use of aqueous hydrochloric acid (1:10 conducted with dollar),

Auto loader to suck in the course of the preceding spout nozzle into the bins 20 ~ 50cm. When the material inside the material runs out, suction machine cannot breathe material auto loader when no material will automatic alerts, you should stop the suction operation. Be expected to fill the tank material, restart start suction operation. When the material inside the material can breathe, but still alert suction machine, you should immediately stop authorities off the power, check the motor overload, troubleshooting and then perform suction operation.

Auto loader during use, pay attention to check whether the suction tube is inserted into the material and whether the material, the system is relatively closed, and over whether the hopper filter seals seal needs to be replaced, if the filter is clogged and the need for clean-up or replacement.

Cleanup auto loader, first stop the job, and then open the filter cover, remove the filter, the filter gently shake, shake off the dust and dirt, then wipe with a clean cotton assembly.

During use, periodically check and clean the suction machine and air cleaner filter. Recommendation per shift (8 hours), be sure to clean the air filter once, so as not to clog the air intake to burn out the motor. Hopper built with the filter, please regularly check or found to reduce the absorption quantity, the spring buckle relax on the hopper, remove the lid remove the filter, eliminating dust attached to the representation, to keep good ventilation suction enhancement.

The machine can be sucked or motor overload automatically stop the job and in the absence of material alarm, then press the off button. After feeding or troubleshooting before turning back to normal operation. (If the motor overload display to power after a reset).

Fan wiring is reversed. Switch any two fan power cables.

This may be due to the poor quality of dispersant or auxiliaries selected by the manufacturer, which causes poor diffusion and inter-solubility and affects the physical and mechanical properties of the products.

The color masterbatch is not carefully tested and the pigment is too little or too much Inaccurate measurement at the time of use, domestic enterprises, especially small and medium-sized enterprises, the phenomenon of random measurement exists in large numbers The matching of masterbatch and resin is problematic, which may be due to the improper choice of carrier of masterbatch, or the manufacturer may change the resin variety at will Improper temperature of the machine, the masterbatch stays in the masterbatch machine for too long Handling procedure: Firstly, check whether the resin variety matches with the masterbatch and whether the measurement is accurate, then adjust the machine temperature or speed, if there is still a problem, contact the masterbatch manufacturer.

This is often caused by the injection molding machine. Different injection molding machines have different mechanical conditions due to different manufacturing, usage time or maintenance conditions, especially the difference in the tightness of the heating element and the barrel, so that the dispersion of the masterbatch in the barrel is not the same, and the above phenomenon will occur.

Some masterbatches have high pigment content (or dyestuff), in this case, the migration phenomenon is normal. Especially for the masterbatch with dyestuff added, serious migration phenomenon will occur. But this does not affect the quality of the products, because after the color masterbatch is injected into the products, the pigment is in the normal color development concentration in the products."

The density and melt index of different resin brands will be different, so the performance of the resin will be different, and the compatibility with the masterbatch will be different, thus the color will change.
