The Growing Market for OEM Car Parts Quality, Reliability, and Value

Investment casting, also known as lost-wax casting, is one of the oldest techniques and is widely favored for its ability to create complex shapes with smooth surfaces. Here, a wax pattern is coated with a ceramic material. Once the ceramic is hardened, the wax is melted away, leaving a cavity that is then filled with molten aluminum. This process allows for high detail and accuracy and is often used in industries where precision is paramount, such as aerospace and medical devices.

If there are more impurities in the oxide film in stainless steel precision casting, its purity will be low and transparency will decrease. The impurities in the oxide film are mainly derived from the stainless steel casting itself, and part of it comes from the oxidation bath. Therefore, appropriately reducing the content of alloying elements in the casting can minimize the content of impurities.
