As the key moving parts in the auto control arms, high quality bushing could improve the comfort, durability and safety of whole auto chassis. Producing high-quality bushing has strict requirement on the raw material control, manufacture technique and testing process. It is not a small challenge to a manufacture company. To produce the reliable and high-quality bushing, DLZ implements strict management and control on the material, tooling, equipment, manufacturing and final performance testing. In addition, DLZ insists to adopt natural rubber (NR) as the foundation material of all bushing to reach the perfect balance between comfort and durability.
