2.Application of differential air shaft
A.The applicable Machine
It is used for slitting machine,coating machine,cutting machine,printing machine,compounding machine,paper making machine,bag making machine, embossing machine and so on .It can greatly improve the working efficiency and the quality of products.

B.The applicable Material
Differential air shaft has been widely used in plastic film including electronic, capacitor, battery film, plastic wrap,packaging,
composite film, metal foil such as copper foil and aluminum foil, paper and pvc sheet.

3.The advantages of our products
1). High quality material for the base shaft and spare parts

The body of the differential shaft is made from steel or stainless steel.We will check the surface roughness,straightness, dynamic
balance,cylindrical and so on to make sure it's qualified to use.

The friction plate can be made from polyurethane, polyethylene,or rubber.They has good consistency of dynamic and static friction
coefficient, less affected by temperature ,high wear resistance and long service life.It's good to realize max tension
required.And we can customize according to customer’s drawing or special requirement.

2).Surface Treatment
Blacking,polishing,anodize,chrome plating,zinc plating,nickel plating,tinting.

The overall quenching and tempering treatment improve the wear resistance and corrosion resistance,which make it possible to use in a variety of environment.

3). Quality control
We have the quality control system during the whole production from the very beginning to the end and our principle is to make
sure each shaft is qualified.
