Accurately speaking, some tooling costs involved in precision casting are probably lower: the production costs of auxiliary clamping tools (auxiliary tools) such as molds, molding tools, sizing tools, spreaders and cover plates for shell making involved in the production process. As for molds, forming tools and sizing tools, you can find a mold factory or a mechanical processing factory to help you make them, and other temporary or simple auxiliary clamping tools can be made by yourself.
