Launching of YWY’s High-tech Industrial Zone Project

YWY’s newly invested high-tech industrial zone is located on Wafangdian’s western suburbs. The total area is 188000 square meters and the total construction area is 125000 square meters.

Our technical transformation adheres to the principle of high starting point, high level and high quality. We adopt the new technology, new techniques and new materials which are internationally advanced and reliable. We aim at the development of heavy machinery’s core market like metallurgy, ports, cement, mining and engineering machinery etc. We also develop the high-end bearing market like precision metallurgy bearings, slewing bearings, engineering machinery bearings and urban rail transit bearings etc. With this high-tech industrial zone, we’ll expand the import replacement of high precision heavy machinery bearings, develop a large number of internationally competitive high-tech products and build the most advanced precision bearing processing base in China.

The first phase of the high-tech industrial zone project has been launched, which is expected to achieve 800 million yuan sales revenue and form the heavy machinery bearing production scale about eight hundred thousand sets per year.
