Product Q&A

Q:Are you a factory or a trader?

We are a factory, and in China we are a leading enterprise in the hydraulic industry. We have two factories covering an area of 180,000 square meters, with more than 700 employees and more than 1,000 sets of production equipment.

Q:Do you support OEM and ODM?

We can accept both.

Q:What is your after-sales service?

Our products come with a 14-month warranty. If any quality issues arise during this period, we will replace the parts for free for maintenance, or directly replace the new cylinder.

Q:Do you have any cylinder surface treatment processes?

Our company has 6 complete surface treatment production lines. We can perform chromium plating, zinc plating, copper plating, copper melting, QPQ, and laser cladding.

Q:How to ensure the cylinder sealing performance?

We use high-quality imported or domestic first-line brand seals (such as Hallite, Longli, etc.). Our cylinders will undergo pressure resistance tests and pressure holding tests higher than the rated working pressure before leaving the factory to ensure long-term stable operation without leakage within the rated pressure range.
