Company Profile

Yangzhou wutingqiao cylinder liner Co., Ltd. is a large enterprise specializing in the production of cylinder liner products. Its predecessor was Yangzhou cylinder liner factory, a designated backbone enterprise of the former Ministry of machinery. It has a production history of 50 years. In 1999, the enterprise was restructured into a limited liability company. The company is located in Yangzhou Weiyang Economic Development Zone, covering an area of 150000 square meters, including a construction area of 80000 square meters, with a total asset of 750 million yuan. It has more than 1000 sets of main production equipment, more than 100 casting and machining production lines, and an annual output of 10 million various cylinder sleeves. The product sales revenue, technology R & D capacity and quality management level are in a high position in the same industry in China.

The cylinder liner products produced by the company have more than 200 specifications and varieties, and the product diameter ranges from Φ 75- Φ 500mm, mainly serving commercial vehicles, construction machinery, ships, generator sets and other fields. In recent years, although the economic situation at home and abroad has declined, the economic structure has been adjusted and the industrial production has fluctuated greatly, the product sales of our company has remained basically stable and growing, with an annual output of nearly 10 million cylinder liners. The sales of cylinder liners of commercial vehicles and construction machinery have always been at a high level in the same industry in China.

The market share of diesel engine products of commercial vehicle companies exceeds 50%. In China, they are Weichai Power Co., Ltd., Wuxi Diesel Engine Plant of FAW Group, DEUTZ FAW (Dalian) diesel engine company, Yuchai Machinery Co., Ltd., Shanghai Diesel Engine Co., Ltd., Dongfeng Motor Group Co., Ltd., SAIC Fiat Hongyan power assembly Co., Ltd., Guangxi Cummins Industrial Power Co., Ltd., Xi'an Cummins Engine Co., Ltd Beijing Foton Cummins Engine Co., Ltd., Jiangxi Isuzu Engine Co., Ltd., Tianjin LOVOL Power Co., Ltd., NAC Iveco and other dozens of main engine plants are suppliers of key main engine plants.

The company produces the cylinder liner of ship medium speed machine with high starting point and assembly line. The casting adopts automatic NC centrifuge for profiling pouring, with light blank weight and stable quality. Cooperate with Jiangsu University of science and technology to develop materials and processing technology suitable for heavy oil and high explosion pressure. Medium speed engine cylinder liners are supported by Shaanxi diesel heavy industry Co., Ltd., Hudong Heavy Machinery Co., Ltd., China Shipbuilding Power Co., Ltd., Weichai Heavy Machinery Co., Ltd., Yuchai Machinery Co., Ltd., Guangzhou Diesel Engine Factory Co., Ltd., Ningbo Zhongce power Electromechanical group Co., Ltd, In the international market, it has developed into a supplier of medium speed engine cylinder liners from Wartsila, Finland, Mann, GE and caterpillar.
