Our hydraulic products include: hydraulic ram, hydraulic cylinder, cylinder, large-scale cylinder and large oil cylinder.

Our cylinders are widely used in these industries: construction engineering, shipbuilding, metallurgy, mining, petroleum, railway and other industries. Our main hydraulic cylinders include heavy duty metallurgy hydraulic cylinder, construction machinery hydraulic cylinder, tension hydraulic cylinder and other non-standard cylinder.

Production Process

1. This is a warehouse of raw materials. Materials include 45#, 40cr, 20crMnTi carbon steel. Clients can also choose other materials according to your actual condition.

2. Stripping process: Our automatic centerless machine is stripping raw materials. It makes the post fine-processing much easier.

3. Straightening and calendering machine is mainly used for the precision straightening and calendering of medal rods in accordance with the design drawing.

4. Fine polishing workshop
(1) The total fine polishing staff consists of over 30 highly trained technicians, each of them possessing over 10 years of industrial experience. We also have 7 CNC centerless grinding machines for the cylindrical processing of steel materials, achieving a maximum diameter of Φ8mm-Φ1000mm and a length of 13,000 mm. thanks to our committed technicians and efficient machine, we can meet any processing requirements of clients.

(2) Cylindrical grinder: Our company totally has 4 cylindrical grinders. Among them, one is CNC cylindrical grinder, with a high degree of processing accuracy: cylindrical run-out < 0.02mm, straightness < 0.05mm, external diameter < 0.01mm. This grinder can satisfy any requirement for fine processing.

The whole processing is in strict accordance with the design drawing.

5. This is a picture of our electroplating workshop. Our technicians cover products with a chrome plate of 20 μm thick, vastly improving capacities like hardness, wear-resistance, temperature resistance and anti-corrosion.

6. Polishing machine: After those above steps, each workpiece will go through the polishing process. It makes products bright and beautiful, obtaining a roughness less than Ra0.3um.

7. Inspection: We have strict standards and requirements for products. When it comes to inspection, each component or part will be checked according to the design drawing. Besides, we adopt thickness measuring device for thickness inspection and pick out substandard products.
