Sichuan Gaodete Science&Technology Co., Ltd was established in 2010 with a registered capital of 10 million, located in the captial of vanadium and titanium-----Panzhihua Vanadium and Titanium Industrial Park, Sichuan, China. Our company is currently the only one in Southwest China specializing in non-uniform permanent magnetic metal magnetic liner, polyurethane liner wear carbon nano tubes, and ultra-high molecular weight polyethylene pipe, sheet metal research and production enterprises. 　　Metal magnetic liner is composed of three parts: a metal body (housing), the permanent magnet (magnet cover polyaddition) and the elastic layer. The metal body is a major component of metal magnetic liner, it is to protect the magnets from external shocks, and have sufficient mechanical strength and suitable permeability. The magnetic induction intensity of the shell surface should meet the needs of adsorbed protective layer.
