  • Description: To analyze the hardness of the Household Product Mould(FURNITUREMOULD) , we found the corresponding solution: 1. The right to choose the mold steel, should choose the high hardenability of large injection mold is high alloy steel 2. Strengthen the inspection of raw materials to ensure that the raw materials meet the requirements of poor raw materials, reasonable forging steel and spheroidizing annealing, to ensure that the good microstructure of carbon tools is not easily annealed many times, in the case of graphitization 3. Strictly implement the forging process and the spheroidizing annealing process to ensure a good preparation group before heat treatment 4. Heat treatment should completely remove the rust and scale of the mold surface, and pay attention to the protection of heating, as much as possible by vacuum or protective atmosphere heating and quenching, salt bath heating deoxidation process should be good 5. Properly develop the mold heating and quenching process parameters to ensure sufficient phase change, rapid cooling at a critical cooling rate greater than the cooling rate, in order to obtain a qualified microstructure 6. Correctly select the quenching cooling medium and cooling method, strictly control the classification and isothermal temperature and time) Strictly control the alkali bath water content. The quenching cooling medium used for a long time is often filtered and periodically replaced, kept clean, and the quenching and cooling characteristic curves are periodically tested. 7. Mold size, prolong the time of impregnating and quenching the cooling medium, preventing the mold quenching and cooling medium temperature from being too high 8. For molds with high hardness requirements, the surface strengthening treatment can be used for deep cooling. Click Daily Necessities Mould to learn about more information.
