What are the difficulties when the mold is just getting started?
I think one of the difficulties is reading maps. I'll give you an assembly drawing of the mold. You should be able to see the assembly relationship of each part from the drawings and see what kind of work the mold will produce. The other is the processing sequence of each part of a set of molds, which part to dry first, then which part to dry, which process to do first, and which process to do later. Sometimes the wrong sequence may lead to the scrapping of parts or increase the processing difficulty. For example, it is much more convenient to process holes first than shafts first, and vice versa.
