Yesterday, when sorting out a quotation customer information, I asked the customer a question: "what material is your product made of and what kind of plastic material are you sure?" The customer immediately asked, "what is the relationship between the plastic material and the quotation?". Today, I'd like to talk to you about the relationship between the selection of plastic materials and the quotation of plastic injection moulds?
In fact, what is the relationship between the plastic materials used in the products and the quotation of molds? Because the different plastic materials used will affect the selection of plastic injection mold steel. For example, ordinary plastic materials: ABS, PP, PA and other materials, they will not wear steel in the daily injection production process, and the wear is very small. If the production requirements of plastic injection mold are not so high, steel materials can choose 718. However, if the plastic materials used in your products are such as: PA6, PA6 + 30% GF and other engineering materials, then for the selection of plastic injection mold steel, you should choose materials with enough hardness, such as H13, etc.
Therefore, the plastic injection mold quotation needs to know clearly the material used by the customer products, in order to make it more convenient for the plastic injection mold factory to provide customers with the exact price.
