A. The stretching system.

The stretching cylinder lifts the stretching slider, which keep the stretching system on the rail, and in right working position.

1. The distance between the stretching cylinder and the rolling wheel should be checked every month, to make sure there are 0.1-0.2mm distance, then the rail will not be damaged easily.

2. Check regularly if the screws and bolts are fixed tight on the stretching cylinder.

3. Check regularly if the the solenoid and air tubes are leaking air.

B. The blowing nozzles and the seals

The small compensation holes on the blowing nozzles are used for making sure the pressure in & external the screws are the same.

The blowing nozzles should be checked regularly, and the damaged or worn out seals should be replaced.

C. Cooling water circulating.

The flow quantity of the cooling water should be checked regularly to make sure it can provide enough cooling water to the molds.

The filter and water tank inside the chiller machine should be check every month too.

D. Air supplying system

This system is working for handling and distributing the high pressure air

The air pressure indicator on the control panels should be checked often to see if the pressure is right.

The water inside the oil filter should be drained every week.

E. Lubricating system

The external parts of the lubricating system should be cleaned often.

The lubricating oil quantity should be checked every day to make sure there are enough lubricating oil or butter there.

All necessary parts should be lubricated regularly.
