We control the quality of raw materials very strictly from purchasing. Each batch of raw material is required to provide quality certificate to ensure that chemical and content non-metallic inclusions of the raw material meet relevant standards, and the furnace number can be traced according to the certificates.

The forging of bearing products mainly come from Formas Precision Forgings (Dalian) Co., Ltd., which is wholly-owned by Italy. Use high-power microscope, hardness tester and other equipment, test the metallurgical structure and hardness of the forged piece after annealing. 

Meanwhile, we require the forging leave enough turning volume to remove the decarburized layer, then the material can be allowed to enter the factory when matched the relevant standards. This made a stable foundation for product quality.
