brake cylinder

Our company is the first one that manufacture railway rolling stock and locomotive fittings with spinning technology. According to the actual needs, absorbing domestic and international advanced cold, hot spinning technique, after a long-term exploration and research and independent innovation, we successfully develop spinning technology applied to variety of large-diameter thin-walled cylinder, manufacture relative equipments to meet the technology, and manufacture more than 20 kingds of products, as spinning brake cylinder for railway rolling stock and locomotive, non-welding line hot close cylinder reservoir, etc..

1. spinning brake cylinder for railway passenger cars, wagons, subway vehicles, railway motor cars

Spinning brake cylinder with variety of sizes is made of high-quality carbon steel plate by forming strongly swirling thinning, that hs characteristics of the inner surface of high precision, light weight, reliable sealing, anti-fatigue, corrosion resistance, long life and other significant merits. It has been applied to all railway wagons in China, at the same exported to applied to the southeast sector, the Middle East, Africa, South America as the part of railway cars.

2. non-welding line hot close cylinder reservoir

Learning, absorbing, innovation and development the hot close spinning core technology, we RD non-welding line hot close cylinder reservoir with variety of sizes and the body has no welding line that is initiative in China.

3. Spin split-type piston

Absorbing current domestic and foreign advanced spinning split technology, we RD and manufacture spin split-type piston for brake cylinder of railway wagon. The piston has the characteristics of advanced structure, light weight, reliable air-tightness and interchanngable with casting piston, that is domestic initiative and pushes piston manufacture technology development.
