Copper sleeve mold manufacturing accuracy

Release date:2018-03-07 The author: Click:

The working life of the copper bushing die: The irrational structure and the excessive grain size caused by the heat treatment result in a decrease in the main properties such as the toughness of the die, cold and hot fatigue properties, and anti-wear properties, affecting the working life of the die.


Copper sleeve mold manufacturing costs: as the middle part of the mold manufacturing process or the final process, heat treatment caused by cracking, deformation and poor performance out of tolerance, in most cases the mold will be scrapped, even through the repair can continue to use, will also Increase working hours, extend delivery time, and increase mold manufacturing costs. It is the heat treatment technology and the quality of the mold that are closely related to each other, making these two technologies mutually promote and improve together in the process of modernization. In recent years, the rapid development of international mold heat treatment technology is vacuum heat treatment technology, surface hardening technology of copper sleeve molds and pre-hardening technology of mold materials.


Accuracy in the manufacture of automotive die bushings: Inhomogeneous, incomplete, and incomplete heat transfer caused by excessive residual stresses caused by the heat treatment process, assembly and mold deformation during the heat treatment, thereby reducing the precision of the die, or even scrapped.


The strength of the mold: improper heat treatment process, non-standard heat treatment operation, or incomplete state of the heat treatment equipment, resulting in the strength (hardness) of the treated mold does not meet the design requirements.
