B. Technical Treatment: Quenched and tempered.1.5-1mm,or 1.03mm per millimetre.
3. Seal Kits
According to customers' requirements and work condition,we will choose suitable seal kits,including:Hallite,NOK,SKF,Parker,Merker,Trelleborg,China made,Taiwan made.We will supply you suitable seal kits to ensure hydraulic cylinders a long lifetime,easy maintenance and simple repairing.
4. Inspection and Testing
A. We have professional quality control department,every step from raw material to finished product is in the same factory,each procedure will be tested by professional inspector.
B. Before hydraulic cylinder is assemblied , every spare parts would be measured and cleaned .After hydraulic cylinder is assemblied , pressure test would be carried out one by one.We ensure the testing pressure is 30%-50% higher than rated pressure in almost one hour's test.Each hydraulic cylinder must be tested without any leakage.
Not only we could manufacture all kinds of OEM hydraulic cylinders according to the drawing from our customers,but also we could make a design according to customer's requirements.If you require our engineer to make a design,pls advise us the following specification:
1. Rated pressure
2. Working pressure
3. Test pressure
4. Working condition and environment ,for example ,temperature ,working frequency
5. Pulling force ,and return stroke force
6. Pulling and return speed
7. Assembly size
8. Seal ring requirements .For example , brand ,seal material etc .
9. Tube and piston rod raw material requirements
10. Piston rod surface treatment requirements, for example chromating film thickness , Surface hardness etc .
11. Painting and other spare parts requirements .
