Seal technology development stage V

Seal technology development stage V Seals have influenced not only the applicable functions of various types of working cylinders, but also the design of the cylinders. Now the design of very small pistons, piston rods and integrated seals has greatly improved the cylinder travel. As an integrate... Read More

Sealing technology development stage four

Sealing technology development stage four A typical example in the history of sealing is the overfilleted pneumatic seal in 1970, which was designed to retain a lubricating film at the edge of its working area and is used in unlubricated pneumatic systems. The application of this type of seal, on... Read More

Sealing technology development stage three

Sealing technology development stage three Due to the modern industry has put forward more and more high requirements for seals, such as small volume, high pressure resistance, excellent physical and chemical properties, which leads to the diversity of the evolution of seals whether rubber or oth...
