Common Faults and Troubleshooting of Die Casting Machine

Die casting machine is a kind of machine which is used to process all kinds of metals. It is widely used in the industrial field. Although the pneumatic die casting machine has rich functions and high production efficiency, it will also have a variety of failures in the operation process. The following describes the common faults of aluminium die casting small machine and how to removal them. 

No or Insufficient Pressure in The system

This kind of failure may be caused by the wrong steering of the hydraulic pump, improper adjustment or damage of the relief valve, failure of the hydraulic pump, serious pipeline leakage, etc. At this time, the operator needs to adjust the direction of the motor, adjust the relief valve or replace the valve, repair or replace the hydraulic pump, overhaul the pipeline. 

Insufficient Fuel Supply of The Machine

The insufficient oil supply of the hot chamber die casting machine may be due to insufficient oil in the oil tank. At this time, it is necessary to replenish oil and check whether the pipeline leaks. In addition, it may be due to the hydraulic pump failure or low speed, at this time, it is necessary to repair or replace the hydraulic pump. If the pump, valve, hydraulic cylinder and pipeline leak, it will also lead to insufficient oil supply of the vertical die casting machine. At this time, it is necessary to repair or replace the damaged components. 

Excessive Temperature of Hydraulic Oil

This fault may be caused by the cooling system is not turned on, at this time, turn on the cooling system to removal the fault. A large amount of dirt accumulated in the cooler or the damage of the cooler itself will also lead to this fault. At this time, the cooler should be cleaned or replaced. In addition, the failure of the hydraulic pump and the viscosity of the hydraulic oil is too large or too small will lead to this fault. At this time, it is necessary to replace the hydraulic pump or replace the appropriate hydraulic oil. 

Abnormal Vibration and Noise

If there is abnormal noise or vibration in low pressure die casting machine, it may be caused by hydraulic pump failure and relief valve failure. The hydraulic pump and relief valve should be repaired or replaced in time. In addition, the oil level in the oil tank is too low, the oil suction pipe is blocked or air leakage can also cause this fault. At this time, it is necessary to add proper amount of oil to the oil tank and repair or replace the oil suction pipe. If the pipes in the hydraulic die casting machine are not properly arranged, it will also cause abnormal vibration and noise during operation, so it is necessary to rearrange the pipes. 

When the energy-efficient die casting machine failure, we should timely check the various systems of the multifunctional die casting machine, and timely determine and removal the fault. If the automatic die casting machine works in abnormal condition for a long time, not only the machine itself will be damaged, but also may endanger the safety of the operator.
