The process of injection molding is a crucial step in manufacturing plastic parts. Drawing the mold diagram is a crucial first step in the entire process. When drawing a mold diagram, it is necessary to first draw a process diagram to ensure compliance with the model requirements and accurate dimensions. If there are no other problems besides burrs after processing, then the difference between the test mold and the final mold is not significant.
Proofreading and reviewing drawings are also indispensable steps. In terms of plastic parts, it is necessary to check whether the flow of plastic materials, shrinkage cavities, weld traces, cracks, demolding slopes, etc. will affect the performance, dimensional accuracy, and surface quality of plastic parts. At the same time, it is necessary to ensure that the pattern design is sufficient, the processing complexity is moderate, and the correct shrinkage rate of the molding material is selected. In terms of molding equipment, it is necessary to ensure sufficient injection volume, injection pressure, and clamping force. At the same time, it is necessary to check whether there are problems with mold installation, plastic parts of the core, release, and the normal contact between the injector nozzle and the muzzle.
Mold repair is another important step in the process. Before repairing the mold, it is necessary to carefully analyze the adverse phenomena caused by the plastic parts, identify the causes of the defects, and determine remedial measures. In general, attempts will be made to change the molding conditions to solve the problem. If the problem still persists, it is necessary to consider repairing the mold.

Organizing and archiving materials is also essential. From the design of the mold to the successful processing and inspection of the mold, it is necessary to systematically organize, bind, number, and archive the technical data generated throughout the entire process, including task books, drawings, technical manuals, mold assembly drawings, mold part drawings, base drawings, mold design manuals, inspection record sheets, and mold repair records. Although this process may seem tedious, it will be very useful for future mold maintenance and new mold design.
