Established in 1971, Yamano initially was set up for manufacturing home hardware. Till 1988, the manufactory started to concentrate on bicycle frame fittings development.

In 1994, aluminum alloy was first adopted in house. Meanwhile, we introduced several advanced CNC machining centers and then focused on suspension frame fittings production.

Due to the huge demand of the market, we founded the other manufactory, Chen Hei Enterprise CO., LTD, in 1999. Moreover, we began to develop forging mold by ourselves to fulfill our customers’ need.

We keep improving product quality and have set many production standards; therefore, we got ISO 9001 & 2000 certificate in 2008. In the meantime, as a result of customers’ strict precision request and cost consideration, we decided to introduce four oil hydraulic forging presses with 2000 tons, 1200 tons, 500 tons.

Chen Hei devotes much effort to maintain its reputation for quality. Pursuing and insisting on higher quality are our ultimate goal. We live our philosophy without compromise. And we have over 45 years of experience in metallic alloy processing and finishing. Therefore, reliance and satisfaction are what we can ensure you now and in the future. Chen Hei shall be the best partner for you. That is our promise.
