Problems solved by technology

[0002] With the advancement of science and technology and the development of society, the application fields of polymer materials are becoming wider and wider, so that society has higher and higher requirements for polymers, especially the support ring products in hydraulic cylinder pistons or guide sleeves; currently on the market There are many defects in these products, such as insufficient elasticity and insufficient strength. When installing and using, it needs to be installed according to the diameter of the piston and the guide sleeve, and the opening is installed, but after the opening, the original size cannot be restored, resulting in extrusion or cutting of the installation. Consequences, loss of manpower and material resources
In addition, the corrosion of the cylinder barrel will also aggravate the wear of the support ring
