Injection molding in China is an essential process for manufacturing various industrial products. With the rapid development of the plastics industry and the extensive application of plastic products in fields such as aerospace, electronics, machinery, marine, and automotive industries, the demands for molds are increasing. Traditional mold design methods are no longer sufficient to meet modern requirements. In contrast, Computer-Aided Engineering (CAE) technology offers clear advantages in improving production efficiency, ensuring product quality, reducing costs, and lowering labor intensity.
In the injection mold processing sector, a range of CNC (Computer Numerical Control) machining technologies are widely employed. Among these, CNC milling and machining centers are the most frequently used equipment, while CNC wire cutting and CNC EDM (Electrical Discharge Machining) also play significant roles in mold processing. Wire cutting is primarily used for processing various straight-walled molds, such as die and punch molds in stamping, inserts, and sliders in injection molds, as well as electrodes in EDM processes. For mold parts with high hardness, traditional machining methods are often ineffective, and EDM is typically used. Additionally, EDM is suitable for complex shapes in mold cavities, such as sharp corners, deep cavities, and narrow grooves. CNC lathes are primarily used for processing standard rod parts and rotational mold cavities, such as bottle and basin molds, as well as forging molds for shaft and disc parts. The use of CNC drilling machines in mold processing can also significantly enhance machining precision and shorten processing cycles.
Molds have a wide range of applications, serving as essential tools for forming nearly all components in modern manufacturing. As such, the mold industry is a crucial part of the national high-tech sector and a valuable technical resource. Future development trends will focus on optimizing mold system structure design, integrating CAD/CAE/CAM with intelligent features for molded parts, enhancing the forming and processing techniques, improving mold standardization, and raising the precision and quality of mold manufacturing. Efforts will also be directed toward reducing surface grinding and polishing work and shortening production cycles. Additionally, research and application of high-performance, easily machinable specialized materials to enhance mold performance will be key areas of focus. To meet the diverse market demands and support the prototyping of new products, rapid prototyping and quick mold manufacturing technologies will become significant trends in mold production over the next 5 to 20 years.
