The trailer suspension is a suspension system designed to connect the wheels and frame to the body of the trailer to transmit forces and torque between the wheels and frame, and to absorb the impact force on the trailer frame or on the trailer body imposed by rough road surfaces and other objects. It also reduces the vibration and ensures a smooth drive for the operator and the trailer contents.
All the axle torsion arm forgings here at our company are manufactured with carbon steel and mature forging technology of "JianXin", besides, all of our forged products are designed professionally and have passed strict testing procedures to ensure their quality.

Mold development process
The R&D team conducts CAD design, CAM, UG, SOLIDWORKS modeling work.
We use superfine die steels as the raw material, allowing them to be processed with a CNC center, ensuring that the die steel’s precision is ensured and has excellent fatigue resistance, abrasive resistance, making sure that the forgings are produced in high quality.
There are more than 2000 sets of molds here at our company. The customers can choose any of them for processing to minimize cost. We perform inventory taking, clearing and recording every week to ensure that the production proceeds as scheduled.
Our mold warehouse is managed by following the IATF16949 quality management system and “6S lean managementâ€, giving a long service life to the mold and making it convenient for use and storage.
