This video details the entire plastic injection mold manufacturing process, from design to final testing, where every step is crucial. First, plastic injection mold design is the starting point of the manufacturing process. At this stage, engineers use advanced Computer-Aided Design (CAD) software to create a detailed plastic injection mold design based on customer needs and product characteristics. This stage involves not only the plastic injection mold's size and shape but also material selection, cooling systems, and gate design. The success of the design phase directly impacts subsequent production stages, thus requiring meticulous consideration and multiple revisions.
After the design is completed, the plastic injection mold enters the CNC (Computer Numerical Control) manufacturing stage. In this stage, the CNC machine formally processes the metal material into the initial shape of the plastic injection mold according to the design drawings. CNC technology ensures extremely high machining accuracy, ensuring that every component of the plastic injection mold meets design standards. At this point, process engineers strictly monitor the machining process to ensure that each step is executed precisely.
Next, the plastic injection mold enters the grinding stage. During this process, grinding machines are used to further improve the smoothness and precision of the plastic injection mold surface, ensuring that the final injection-molded product has excellent surface quality. This process is crucial for reducing subsequent product defects, as the surface roughness of the plastic injection mold directly affects the appearance and performance of the injection-molded products.
After grinding, the plastic injection mold undergoes EDM (Electrical Discharge Machining). This technology can process extremely complex shapes and details, especially in precision areas that are difficult to achieve using traditional machining methods. The application of EDM technology greatly enhances the flexibility of mold design while ensuring high precision and stability.
The final step in plastic injection mold manufacturing is 3D inspection. This step is critical, aiming to ensure that the dimensions, shape, and various technical parameters of each plastic injection mold meet design requirements. Using high-precision 3D measuring instruments, inspectors can detect minute errors for timely adjustments and corrections. This not only helps improve plastic injection mold quality but also prevents potential production problems before production begins.
Finally, after ensuring the plastic injection mold manufacturing meets high standards, the manufacturing team installs the mold on the injection molding machine for final testing. The goal of this testing phase is to verify that the plastic injection mold can accurately and quickly produce large-scale injection-molded products. Through repeated trials, it is ensured that the plastic injection mold meets all production requirements and can maintain stable production efficiency during peak demand periods.
