Analysis on Seven New Trends of Mold Development Technology in China
In the past two years, China's domestic mold technology have very fast development, mainly as follows:
1> mold integrated manufacturing unit and technology popularization; commercial Internet to the mold and its industrial chain extension;
2> 3D printing in the mold manufacturing in a wide range of applications ;
3> Mold of the intelligent; lightweight new materials and large plastic mold out
5)> lightweight new materials and large plastic mold appearance and optimization;
6> large-scale progressive die technology is mature;
7> Use standard parts for manufacturing and so on.
(1) Mould integrated manufacturing unit and the popularity of technology. In addition to the automatic feeding, stamping, stacking, thickness grouping, core assembly and product output, hinge assembly connection and other functions, there have been complex motion structure, in-mold heating, forging, local heat (tissue) control, mold Internal welding, tapping, local injection molding, die cutting, in-mold detection process combination process. It is particularly worth mentioning that this exhibition is the emergence of the plastic parts of the mold in the eager, boron steel mold in the fervent and the motor pen-shaped core of the blade edge blanking and other new technologies to create a mold integrated manufacturing unit of the new era. Mold products continue to large, sophisticated, high-performance, integrated manufacturing unit direction.
(2) Commercial Internet to mold and its industrial chain extension. At present, many mold processing equipment enterprises have docked the Internet, and actively build "mold manufacturing + Internet" model, a strong impetus to the mold industry transformation and upgrading.
(3) 3D printing in the mold manufacturing in a wide range of applications. 3D printing application production mold cavity is a new trend in the development of cavity mold. The metal composite material - the combination of the material manufacturing technology is an important direction in the field of 3D printing. At present, it is high-precision manufacturing of complex metal parts by combining the high-speed milling and thickening of the contours.
(4) the intelligent mold. At present, in the plastic mold and die-casting mold industry, there have been mold mould cavity pressure, temperature, flow, cooling process of intelligent control of the mold. In addition, the intelligent mold processing equipment is also rapidly promoting the intelligent manufacturing mold.
(5) the emergence and optimization of lightweight materials and large plastic molds. With the development of lightweight vehicles, lightweight new materials emerging, the domestic mold enterprises have begun to deal with this change, launched a lightweight new material automotive cover mold and large composite mold development.
(6) Large-scale progressive die technology mature, high-speed high reliability of precision progressive die into an important feature. At present, large-scale progressive stamping parts abound, parts larger and larger, more and more complex shape, showing a large-scale progressive die technology into the mature stage. The high precision progressive die on the production of stability, reliability requirements are getting higher and higher, has become an important means of mold manufacturing enterprises competition. Obviously, the large-scale forming parts and small ultra-precision parts of the mold design and manufacturing technology has become a hot mold enterprises concerned.
(7) Mould standard parts tend to fine. In recent years, with the mold types and requirements to improve, mold standard parts has become a mold enterprises to participate in international competition, an important condition, variety, classification is the main trend of the current standard mold parts. The traditional standard parts are more and more, more and more high quality requirements. The new functional structure of the standard unit and more flexible manufacturing standard parts are also increasingly important, as new technologies and innovation to enhance the competitiveness of the new direction.
From the above can be seen, the moment China's mold technology has developed to another new stage, but in order to get a greater breakthrough, but also need to continue to optimize the road.
