Injection machine routine maintaince work could help the machine run better and meanwhile the machine could run much longer.Dakumer has very strong fabrication ability and after sale service. Below is some maintenance work and notice points:

1.Lubrication
Lubrication oil is an important factor of the machine. No operation without lubricating, otherwise the equipment will be seriously damaged. Proper lubrication will lengthen the service life; on the contrary, poor lubrication will result in the wear and heat of parts. The clamping unit of the machine employs auto central lubricating device, and the other necessary moving parts have grease nipples for lubrication.

2.Maintenance of hydraulic unit
As the medium for power transmission, the hydraulic oil is used for lubricating the surfaces of metals. Since the variety and higher performance of the hydraulic equipment, the requirement for hydraulic oil is more and more strict.
In general, hydraulic oil should:
※ Flow freely under the working conditions;
※ Form appropriate seal in the moving accessories;
※ Have no physical or chemical changes while working;
※ Anti-rust and anti-corrosion;
※ Resist certain load and reduce the wear of moving components;
※ Separate moisture, dirt and other foreign substances quickly while static;
※ Suitable for sealing, etc. during working;
※ Fine resistance;
※ Bubbles resistance.

3.Cleaning of the barrel and screw
It is necessary to clean up the barrel when new material is used. Normally it’s no need to clean up the barrel until color change injection has amounted to 20-30 times. You need to do partial or complete cleaning depending on the contamination.

4.Daily maintenance
Operators should pay attention to the running machine. In case of any emergency, press the emergency stop button on the computer panel immediately and then turn off the main power supply. Do not restart the motor of the oil pump until the fault has been rectified.
During the working the operators should do as following:
◎ Listen
In the event of any defect to the motor, oil pump and bearing, there will be abnormal sound.
◎ Smell
The motor may give out smell if it is burned due to overload, ventilation block, electro-thermal coils and plastic in the barrel.
◎ Observe
Check the lubrication system, oil pipes.
Daily safety check
Daily electrical check
Daily hydraulic system check
Mechanical system check

5.Always keep the machine clean.
  Before cleaning up the machine, you should:
Turn off the main power supply and put on a “no power” sign nearly.
  You are required to:
Clean up the surface of the machine with vacuum cleaner and small emery cloth, including covers, pipes and valves etc.

Clean up the hydraulic oil or grease with yarn rage in time.
Otherwise the metal powders and dust stuck on the oil surface will reduce the mechanical precision and increase wearing,

Clean up the powders stuck around the hopper with vacuum cleaner. Otherwise they will bring the oil into the hopper during the process of maintenance to cause loss of the pump and valves.
