Wuxi Hengli Hydraulic & Pneumatic Element Co., Ltd.

Hengli Group is a large comprehensive enterprise involving in developing, manufacture and sales of pneumatic elements and cylinder series. Wuxi Hengli Hydraulic Pneumatic Co., Ltd., a subsidiary company of the group, deals with pneumatic elements; Jiangsu Hengli High Pressure Cylinder Co., Ltd. (Sino-American venture) mainly deals with cylinders.

Established in 1990, the company has developed into a large size enterprise with 250 million RMB sales value in 2007 through many years′ hard working. There is totally 475 staff, among whom, 45 are senior engineers and 70 are mangers. The total floor area is 56000 square meters, among which, 13000 are pneumatic production workshop and 27000 are cylinder plant. The company has passed several international system certifications such as ISO9001, ISO14000 and OHSAS18001.

Many equipment and technique investments have been input these years in order to occupying leading position both oversea and home markets. Some world-class production, processing and inspection facilities have been imported one after another, such as welding robot, heat processing equipment, full auto nickel and chrome plating lines, automatic assembly and inspection lines. The total investment in recent three years has reached to 20 million USD.

The company pays much attention to new products research and development. On the basis of talents fostering and accumulated experience as well as modernized computer assistant design, manufacture and simulation, all kinds of new products bearing world-range quality have been developed, manufactured and sold:

Pneumatic ratio control valve, metal sealing reversal valve, elliptical cylinder, high frequency jet electromagnetic valve and so on; The products are widely used in many fields like textile, costume, paper making, pharmacy and food industry.

Cylinder for excavator, engineering cylinder, metallurgy cylinder and other non-standard cylinders with maximum diameter reaching to 1500mm and maximum stroke 10 meters. The company gives the primacy to quality improvement and customers′ interests. Many breakthroughs and innovation, which are the basis of satisfying customers′ requirements and improving products, quality, have been achieved through years′ development.

Through thorough analysis of detailed application circumstance, the mechanical performance of the cylinders can be greatly utilized by assistant computer technology.

The company has established unique technique and management modes for some important parts and techniques like sealing pieces, high pressure oil pipe, piston rod, plating and heat treatment. For example, surface of piston rod is treated by both nickel and chrome plating so as to improve its rotproofness. Thus, high quality and reliability has been guaranteed.

Fully-enclosed purified lines with constant temperature are applied to mechanical processing, heat treatment, welding, plating, assembly and coating plants. Environmental pollution has been controlled thoroughly, industrial oil contamination issue has been settled and the stability of equipment and system has been improved.

Good reputation and high praises are obtained from all kinds of fields such as engineering, port, hydraulic and loading mechanism because of more than 100 thousand cylinders with various application purposes and high performance, especially the cylinders for excavator. Both the products quality and production scale have ranked No. One in China and reached world class.
