FAQ

Q1:What's the brand name of your products ?
A:Generally, we use our own brand "WTJX", OEM is also available as required.

Q2:Hydraulic cylinder internal leakage?
A: There are 3 main reasons causing internal leakage : Overload, polishing is not well controlled, bad seal kits. As is known to all, vehicles in China are often overload,our products all designed to bear the overload power. We have numerical control machine to assure the polish processing. And we use the imported seals to meet customers' demands.

Q3:Does your piston rod get ruptured easily?
A: Hard chrome plating quenched and tempered 45# steel for piston rod to assure sufficient hardness and toughness.

Q4:What about the quality feedback of your products?
A: Guarantee the quality from the raw material. We have cold drawing production line and nickel-chrome electroplating production line, so we can produce cold-drawing pipe and hard-chrome pipe used for hydraulic cylinder!
