Do you really understand injection molds?

Injection mold manufacturing is a manufacturing method that injects melted plastic into a mold through spray injection to form the desired shape. Before manufacturing injection molds, it is necessary to understand a series of issues. The following are the questions to be aware of when manufacturing injection molds:
1. Product design requirements: It is necessary to know the design requirements of the required product, including product size, shape, appearance requirements, and material requirements. This has a significant impact on the size and shape of manufacturing molds to ensure the quality of injection molded products. So, the design of product drawings and samples are an indispensable part of the manufacturing process
2. Material selection: According to the product design requirements, suitable injection molding materials need to be selected. Different materials have different characteristics, such as hardness, toughness, high temperature resistance, etc. Choosing appropriate materials can improve the performance and durability of products.
3. Mold design: Before manufacturing injection molds, detailed mold design is required. This includes the structure, components, mold opening method, exhaust method, etc. of the mold. The quality of mold design directly affects the quality and production efficiency of the product.
4. Material selection: When manufacturing injection molds, it is necessary to choose suitable materials. Common mold materials include tool steel, stainless steel, aluminum alloy, etc. Choosing suitable materials can improve the wear resistance and corrosion resistance of molds, and extend their service life.
5. Mold manufacturing process: Mold manufacturing is a relatively complex process, including CNC machining, wire cutting, EDM, etc. The accuracy and quality of mold manufacturing directly affect the size and shape of the product.
6. Processing accuracy of molds: The manufacturing process of molds needs to consider the processing accuracy of molds. The higher the machining accuracy of the mold, the better the dimensional stability and consistency of the product.
7. Mold trial and debugging: After manufacturing the mold, it is necessary to conduct mold trial and debugging. This includes the assembly, adjustment, nozzle design, and parameter settings of the mold. Only by conducting good mold testing and debugging can we achieve good injection molding results.
8. Maintenance and upkeep of molds: Injection molds are long-term tools that require regular maintenance and upkeep. Cleaning, lubricating, and repairing molds can extend their service life and reduce production costs.
9. Quality control of molds: Strict quality control is required during the manufacturing process of injection molds. This includes size measurement of molds, material testing, and product testing. Only good quality control can ensure the quality of the product.
10. Storage and management of molds: Injection molds need to be stored and managed before and after use. The storage of molds needs to avoid being affected and damaged by the external environment, and the management of molds needs to be recorded and tracked in order to find and manage molds in a timely manner.
