Description

technical field

[0001] The invention belongs to the precision machining technology, and relates to the improvement of the manufacturing method of metal fixing film sleeves of printers and copiers. Background technique

[0002] The fixing film used in low-end printers and copiers is made of non-metallic sleeves and high-temperature-resistant outer coatings. The non-metallic sleeves are usually made of polytetrafluoroethylene rods, which are mainly processed by injection molding. Its service life is low, the number of copy papers is less than 20,000, and the fastness and resolution of printed products are low. The metal fixing film used in high-end laser desktop printers and copiers is the core component of printers and copiers. The metal fixing film is mainly composed of a metal sleeve and a high temperature resistant outer coating. Among them, the metal sleeve is its key component, which is made of metal materials such as stainless steel or copper alloy. The metal casing ...
