Heat Treatment of High-Temperature Short-Life Hardened Steel Plastic Mould
High temperature short time stainless steel molds are moulds designed for high temperature, short time production. These molds require special attention when it comes to heat treatment. High temperature short time molds are designed to reduce cycle time and improve production efficiency. However, the extreme temperature that these molds are exposed to can cause problems such as distortion, cracking, and wear. To prevent these issues, proper heat treatments must be applied during the mould making process.
High temperature short time molds typically require a preheating step as well as a post-heating step. To create a preheat in these molds, a furnace furnace must be programmed to the desired temperature set point. The preheat step helps to prevent thermal shock, an extreme change in temperature which can cause thermal distortion. After the preheat step, a post-heat treatment must be conducted to ensure proper hardening of the steel. Depending on the type of steel and the required hardness, different post-heat treatments may be used such as carburizing, nitriding, and surface hardening.
Carburizing is a form of surface hardening that is typically used in high temperature short time molds. This process involves introducing carbon into the surface of the steel. The carbon helps to create an outer layer of hardness which increases overall strength and wear-resistance. This hardening step allows for more efficient production as it can reduce cycle time and increase the lifespan of the moulds.
Nitriding is another form of hardening that can be used in high temperature short time molds. This post-heat treatment involves introducing nitrogen into the surface of the steel. This creates an outer layer of hardness which makes the steel more resistant to corrosion and wear. Nitriding also helps to improve the dimensional stability of the steel, which can help to prevent distortion.
Surface hardening is a process that involves hardening the surface of the steel by exposing it to various temperatures. The temperatures and duration of the treatment vary depending on the type of steel and the desired hardness. The heat helps to create an outer layer of hardness, which improves wear resistance and strength. This process can also be used to reduce or prevent thermal distortion.
The post-heat treatments described above are used for high temperature short time moulds in order to improve lifetime and wear-resistance. Proper preheating and post-heating treatments should be applied to all high temperature short time moulds in order to ensure efficiency and longevity. Proper selection of the heat treatment process, the steel grade and the furnace parameters are all important factors in optimizing the performance of the high temperature short time molds. By following the proper heat treatment steps, it is possible to maximize the performance of the high temperature short time moulds.
