Design and production cost of mould. 1. It depends on the precision requirements of the product for the mold. For example, the mold of a watch should have higher accuracy. Probably need 1mu. 2. Mold technology: wire cutting, wire cutting, polishing, etc. 3. Material used in the mold: It also determines the number of times the mold is used. If you need to develop a large number of products. You need better materials. Some mold materials can be used for 3 million times, and some for 200,000 times. These are the factors that determine the production cost. I hope I can help you.
