How We Work:

Company Qualifications	Our client

Production capacity:

1,The major parts made of forged steel and technology for heating processing which import foreign latest science and technology The entire production process is controled by computers. Employing abrasive machining for the form of the gear and intellective-control carburizing and quenching technology for the surface, the gear is with high intensity, strong tenacity and wearability. 2,The key components are selected so carefully which are using the Cr. Ni. Mo steel that made our products have the higher performance than similar products. 3,The piston \Boring rod sleeve\Screw rod inside adoptedstrengthen treatment,steady discharge pressure, smooth operation, less weight, often wearing parts with significantly lengthened life.
Mechanical processing all adopt CNC processing and control size more strictly.
Five assembly lines ,and mechanical professional engineers ensure the higher quality and stable yield,which made us have the confidence of satisfied every customes.
The gas legs we producted with our own intellectual property have a high reputation for its flexibility, maintainability and security.
The engineers with over ten years experiences in this field give tests to every kind of mechina under their meticulous care,and ensure our excellent quality.
