In the manufacturing process, first, three-dimensional modeling is carried out using computer-aided design (CAD) software to precisely plan the structure, dimensions and forming process of the mold. Then, numerical control processing codes are generated with the help of the Computer-aided manufacturing (CAM) system. During the processing stage, technologies such as CNC milling, electrical discharge machining (EDM), and slow wire electrical discharge cutting are comprehensively applied to perform high-precision cutting and forming on materials like mold steel and hard alloys. For complex curved surfaces or tiny structures, special processes such as micro-milling and laser processing will also be adopted. During the manufacturing process, precision inspection equipment such as three-coordinate measuring machines and scanning electron microscopes are involved in real time to ensure that the dimensional accuracy, surface roughness and other indicators of the molds meet strict standards.
This field is highly dependent on technological innovation and experience accumulation, and requires a deep integration of knowledge from multiple disciplines such as materials science, mechanical engineering, and automatic control. For example, the selection of mold materials directly affects the forming quality and the service life of the mold. The material properties can be optimized through heat treatment processes. Mold flow analysis software can simulate the plastic molding process, predict potential defects in advance and optimize the design. In addition, the introduction of intelligent manufacturing technologies, such as automated production lines and digital management systems for molds, has significantly enhanced manufacturing efficiency and quality stability.
The manufacturing of precision molds is widely used in industries such as electronics, automobiles, medical care, aerospace, etc. From mobile phone chip packaging molds to automotive engine cylinder block molds, from medical catheter injection molds to aviation engine blade die-casting molds, their manufacturing levels directly determine the performance, quality and production efficiency of terminal products, and are an important driving force for promoting industrial upgrading and technological innovation.
