Sample mold

At present, the molds for producing samples are all made by simple machining or using low-cost materials (such as aluminum or copper as raw materials). However, it should be noted that parameters that are very important to production, such as temperature, pressure, etc., cannot be represented by such a mold. In addition, their different cooling properties lead to different shrinkage and thermal transformation behavior. It is now recommended to use high-hardness steel to make molds, and the molds can be designed with a single cavity arrangement.
