Production

Raw Material:

LANXESS NBR rubber from GERMANY ,this rubber has the best quality in the world.

BELKTA steel wire with high tensile strength2750Mpa from Belgium.

Good quality materials make our hydraulic hose steady performance, good decentrality and excellent oil resistance.

Factory Workshop: 

• Spiral Machine is 100% Servo electronics control from Japan engineer team’s master work.

  The advantage of the machine is high length control accuracy with tolerance <0.001.

• High strength inner rubber.

  high rubber content >47%, superior impulse performance, impulse >500,000 circles.

Laboratory:  

Strong quality control team, advanced laboratory. 
Before the mass production, test each batch of raw material. 
After the production, test each hose to guarantee a 100% qualification. 
Each hose tested at 2 times of working pressure. 
We do everything possible to supply good quality goods for our customer.
