Metalworking is the technology of making metal materials into articles, parts and components, including not only large parts such as bridges and ships, but also small parts such as engines, jewelry and watches. The following briefly introduces the development trend of metal processing technology:

(1) process synthesis

Process synthesis mainly includes two aspects: one is the integration of material design, preparation and forming, and the links are more and more closely related; The second refers to the integration of multiple processes (such as solidification molding). The synthesis of various technologies can often bring new manufacturing principles or breakthroughs in manufacturing technology, such as fine blanking composite forming technology, semi-solid technology and continuous casting and rolling technology.

(2) Technology synthesis

Technical synthesis means that plastic forming technology is developing into a technical science combining various technologies. Plastic forming technology will rely on new materials, new energy, new media and computer, information, electronics, control technology and so on. In particular, the integration of preparation, molding, technology with computer technology, information technology and various advanced control technologies will continue to develop at a faster speed, and the development direction will highlight the demand of "precision, economy and cleanliness". Such as laser forming, electromagnetic forming, ultrasonic plastic forming, explosive forming, hydraulic forming, pneumatic forming, numerical control incremental forming and so on. It fully embodies the characteristics of the integration of other technologies and plastic forming technology.

(3) Theme synthesis

Discipline synthesis is not only reflected in the integration of traditional three-level disciplines such as casting, plasticity, heat treatment and connection, but also in the integration of materials physics, chemistry and materials science other than computer science, information engineering and environmental engineering. The boundaries between disciplines are becoming less and less obvious, and the infiltration and interdependence between disciplines are getting stronger and stronger. Such as semi-solid metal technology, continuous casting and extrusion, continuous casting and rolling, new technology of powder metallurgy plastic forming, plastic processing after explosive welding or diffusion welding, new technology of composite plastic forming, etc. , all reflect the comprehensive characteristics of the subject.

The above is the development trend of metalworking plastic technology, and the metalworking industry is also making progress in the direction of ultra-precision and ultra-high speed through the application of new industrial technology.
