Precision machining technology is one of the key technologies in mold manufacturing, which directly affects the precision and quality of the mold. In recent years, with the continuous advancement of processing equipment and technology, the precision machining technology of mold manufacturing has made significant breakthroughs. For example, the application of electrospark machining technology in mold manufacturing is becoming more and more extensive. This technology can process mold parts with complex shapes, with high machining accuracy and good surface quality. The mold cavity manufactured by a mold manufacturing company using electrospark machining technology can achieve a dimensional accuracy of micron level and a very low surface roughness, which greatly improves the molding quality of the mold. In addition, laser processing technology has also been used in mold manufacturing. Laser processing has the advantages of fast speed, high precision, and non-contact processing. It can perform processing operations such as cutting, punching, and engraving on the mold, providing technical support for the personalized customization of the mold. In the future, with the development of nanotechnology, the precision machining technology of mold manufacturing will develop in the direction of higher precision and higher efficiency.
