Under the condition that the structure, materials and use conditions of Daily Necessities Mould are unchanged, ensuring the heat treatment quality and adopting the best heat treatment process are the keys to give full play to the potential of mould materials and improve the service life of daily necessities mould. If the heat treatment process is unreasonable or improper operation causes heat treatment defects, it will seriously damage the service performance of the mould and lead to its early failure.
Pre-heat treatment of daily necessities mould working parts blank includes several processes such as annealing, normalizing, quenching and tempering according to different materials and requirements. Correct pre-heat treatment specifications play a great role in improving the structure, eliminating the structural defects of forged blanks, improving the machinability, and improving the bearing capacity and service life of daily necessities mould.
Quenching and tempering of mould materials for daily necessities is the central link to ensure the performance of mould working parts. Whether the quenching and tempering processes are reasonable or not has a direct impact on the bearing capacity and service life of the mould. The heat treatment process specifications should be strictly controlled or advanced heat treatment methods should be adopted.
The purpose of surface strengthening of the working parts of the daily necessities mould is to obtain the effect of external hardness and internal toughness, and to obtain a good combination of hardness, wear resistance, toughness and fatigue strength, thus improving the service life of the daily necessities mould.
