At present, the technical level of China's mold industry is uneven, with great disparity. Generally speaking, there is still a big gap compared with the advanced level of developed industrial countries and Hong Kong and Taiwan.
There is a big gap in both the universality of application and the technical level in designing and manufacturing molds by using CAD / CAM / CAE / CAPP and other technologies in Guangdong machining plant. In the aspect of using CAD technology to design molds, only about 10% of molds use CAD in the design, which is still a long way from leaving the drawing board; Guangdong machining plant has just started to apply CAE to mold scheme design, analysis and calculation, and most of them are still in the stage of trial and animation games; In the application of CAM technology to mold manufacturing, there is a lack of advanced and applicable manufacturing equipment, and the networking rate of existing process equipment (including advanced equipment introduced in recent 10 years) is low due to different computer systems (IBM microcomputer and its compatible computer, HP workstation, etc.), or due to byte difference, operation speed difference, anti electromagnetic interference ability difference, etc, Only about 5% of mold manufacturing equipment have carried out this work in recent years; The application of CAPP Technology in process planning is basically blank, and a lot of standardization basic work is needed; The application of CAD / CAM technology in mold common process technology, such as mold rapid prototyping technology, polishing technology, electroforming technology, surface treatment technology and so on, has just started in China. The software development of computer-aided technology is still at a low level and requires the accumulation of knowledge and experience. The mold processing equipment in most mold factories and workshops in China is old, with long service life, poor precision and low efficiency. Up to now, ordinary forging, turning, milling, planing, drilling and grinding equipment are still used to process molds, and salt bath and box furnace are still used for heat treatment processing. The operation depends on the experience of workers, the equipment is simple and the energy consumption is high. The equipment renewal speed is slow, the technical transformation and technical progress are not strong. Although many advanced mold processing equipment have been introduced in recent years, they are too scattered or not matched, the utilization rate is generally only about 25%, and some advanced functions of the equipment have not been brought into full play.
Guangdong Machinery processing plant is lack of mold design and manufacturing process technicians and skilled workers with high technical quality, especially compound talents with wide range of knowledge and high level of knowledge structure. The technicians in China's mold industry account for only about 8% ~ 12% of the employees, and the overall technical level of technicians and skilled workers is also low. The knowledge of technicians and skilled workers employed before 1980 is aging, and the knowledge structure can not meet the current needs; The employees after the 1980s are lack of professional knowledge and experience, poor practical ability, uneasy and unwilling to learn technology. In recent years, the brain drain has not only caused the decline of the number and quality of talents, but also a new fault in the talent structure, which makes it difficult to improve the technical level of mold design and manufacturing.
