Probably one of the best in the world, this type of PTFE coated steel belts serve packaging industry for global customers.
Steel belts are key components in the machineries of plastic tubes and aluminum-plastic tubes, for packages of toothpaste, cosmetics, food packaging and many other more packaging.
Most of steel belts makers do the welding in their shop floors but outsource PTFE coating from painting shops who are not familiar with steel belts, and practice spread painting on steel belts with poor adhesion quality.
Welding is the key of success manufacturing high quality steel belts. Most of the steel belt manufacturers use standard or normal welding skills on steel belts that also applied to other welding jobs. It requires speciality of skill and process to make good steel belts.
Solar power wafers are made from silicon ingots cut by steel band saws.
LED wafers are made from sapphire ingots cut by band saws as well.
Stainless steel endless belts have been treated harden, with edges straighten and electroplated with synthetic diamond powder. Such kind of steel belts can cut super hard material and brittle material such as monocrystalline silicon, polycrystalline silicon in solar energy, semiconductor and sapphire, ruby in LED field. It also can cut ceramic, graphite, glass and marble as well.
