Processing of manufacturing accuracy of copper sleeve mould
 
Working life of copper sleeve mould: the unreasonable structure and grain size caused by heat treatment lead to the decline of main properties such as toughness, cold and hot fatigue, wear resistance, etc., which affect the working life of the mould.
 
Manufacturing cost of copper sleeve mould: as the intermediate or final process of mould manufacturing, the cracking, deformation and performance overproof caused by heat treatment will make the mould scrapped in most cases. Even though it can still be used through repair, it will also increase working hours, extend the delivery time and increase the manufacturing cost of the mould. It is the close relationship between heat treatment technology and die quality that makes the two technologies promote each other and improve together in the process of modernization. In recent years, the rapid development of International Die heat treatment technology is in the field of vacuum heat treatment technology, copper sleeve die surface strengthening technology and die material pre hardening technology.
 
Manufacturing accuracy of copper sleeve mould: uneven and incomplete structure transformation and excessive residual stress caused by heat treatment result in deformation of mould during processing, assembly and use of mould after heat treatment, thus reducing the precision of mould and even discarding it.
 
Strength of mould: improper formulation of heat treatment process, nonstandard operation of heat treatment or incomplete condition of heat treatment equipment, resulting in the strength (hardness) of the treated mould failing to meet the design requirements
