Shandong Zhiheng Vibration Damping Tech Co., Ltd.

Shandong zhiheng vibration damping technology Co., Ltd. (hereinafter referred to as "the company") is located in No. 5 liaohe street, ningjin economic development zone, dezhou city, shandong province, with a registered capital of 46.4706 million yuan and an area of 100, 000 square meters. Company predecessor was founded in 1996 in shandong NingJin County mechanical spring factory, due to the development needs in 2001 moved to NingJin County galaxy economic development zone, 2005 restructuring renamed shandong NingJin spring Co., Ltd., company's overall restructuring in 2012 for shandong ZhiHeng damping technology Co., Ltd., in February 2015, successfully listed on the new three board (stock abbreviation: ZhiHeng damping, code: 832027).

The main business of the company is the research and development, production, sales and maintenance of spiral spring and rubber cushion pad, which are mainly used in rail transit and construction machinery industry. The company is the only domestic manufacturer that can realize batch supply of vibration damping spring for high-speed emu. It is also one of the enterprises that can simultaneously produce the full series of vibration damping buffer spring and rubber cushion cushion for railway truck, railway bus, high-speed emu, intercity vehicle, subway and light rail. The company's customers include CRRC Qingdao sifang locomotive & rolling stock Co., Ltd., changchun rail coach equipment Co., Ltd., tangshan rail coach Co., Ltd., nanjing puzhen vehicle Co., Ltd., and other rolling stock factories, and has become a qualified supplier of BOMBARDIER, the world's largest transportation equipment manufacturer.

After years of research and development, the company has mastered the manufacturing technology of shock absorber spring in the field of rail transit and construction machinery, and the production of pillow spring, axle box spring, hook spring and tension spring can effectively meet the operation needs of all kinds of mechanical equipment in terms of mechanical properties and environmental properties. The 200km to 350km emu spring developed and produced by the company has been installed in batch on the harmony emu train, and has become the only designated supplier of "fuxing" emu shock absorber spring, realizing a major breakthrough in the emu spring of domestic enterprises, and making an important contribution to the localization of emu parts. At present, the company has taken the lead in mastering the manufacturing technology of the shock absorber spring for the emu unit with a speed of more than 380 km/h, and has successfully developed the spring for the emu unit with a speed of 500 km/h, leading the world. In the field of engineering machinery, the company relies on strong technical strength and professional manufacturing capacity, can consult for all kinds of engineering machinery factory and customize various types of helical spring, such as Japan komatsu PC DH series excavator series excavator spring, Han Guodou mountain spring, hill pushed SD series bulldozers spring and India BEMLBD series heavy duty mechanical spring, etc.

The company is a "high-tech enterprise", with a number of rail transit vibration damping equipment patent technology, emu spring engineering laboratory has been identified as a "provincial engineering laboratory. The company has been awarded as "postdoctoral innovative practice base" in shandong province, and has many honorary titles such as "China patent shandong star enterprise", "dezhou 1351" key cultivation enterprise, national "contract and credit" enterprise and dezhou advanced tax paying enterprise.
