What is the process of plastic mold injection molding for mold manufacturers?
Plastic mold opening is a complex and delicate process, especially for precision molds, which involves multiple processes and problems. In this process, every step is crucial and requires careful design and execution. The following will provide a detailed introduction to the process of plastic mold injection molding:
1. Drawing design:
The first step in mold opening is to carry out drawing design. At this stage, engineers need to communicate fully with the client, understand their needs, and based on this, complete the drawing design.
2. Material selection:
Select appropriate materials to make molds based on the nature and requirements of the product. The quality of material selection directly affects the quality of injection molded products, so this step must be done properly.
3. Mold making:
The production of molds includes multiple mechanical processing steps, such as CNC machining, EDM machining, wire cutting machining, deep hole drilling, etc. The accuracy and quality of these processing steps directly affect the forming effect of the mold.
4. Trial and repair of molds:
Although factors such as molding materials and equipment have been considered in the design of the mold, people’s understanding is sometimes incomplete. Therefore, after the mold is made, trial mold tests are needed to check the quality of the formed parts. If any problems are found, they need to be corrected in a timely manner. The reasons for the occurrence of defects in plastic parts are complex and diverse, which may be problems with the mold itself or process conditions, and need to be comprehensively considered and eliminated.
Before repairing the mold, it is necessary to conduct a detailed analysis based on the specific situation of the defective phenomenon, identify the cause of the problem, and propose solutions. Usually, the molding conditions are adjusted first, and if the problem is still unresolved, mold repair is considered. Repairing molds requires caution, as once the mold conditions are changed, it is difficult to restore the original state. Only by ensuring good performance of the parts can the quality of mold manufacturing be guaranteed.
5. Organize and archive materials:
After the successful trial of the mold, it can be put into production use. If there is no need for production temporarily, it is necessary to properly keep the mold and organize relevant technical parameters for archiving. Plastic mold opening is a comprehensive and strict process that requires designers and engineers to work together to ensure the quality and accuracy of each link, in order to ensure the quality and stability of the final product. May the engineers from Donglai mold manufacturers continuously summarize their experience and improve their technical level in practice, providing customers with better services and products.
