2017 China's mold technology development has a new trend

In the past two years, China's domestic mold technology has made rapid progress, mainly as follows: the popularization of mold integrated manufacturing units and technologies; the extension of commercial Internet to molds and their industrial chains; the widespread application of 3D printing in mold manufacturing; Intelligent; the emergence and optimization of lightweight new materials and large plastic molds; the maturity of large-scale progressive die technology; and the refinement of standard parts.
1. The popularity of mold integrated manufacturing units and technologies. In addition to automatic feeding, stamping, lamination metering, thickness grouping, core assembly and product output, hinge assembly connection, etc., the mold also has complex motion structure, in-mold heating, forging, local heat (tissue) control, mode Internal welding, tapping, partial injection molding, in-mold cutting, in-mold testing and other process combinations. It is particularly worth mentioning that the new technologies such as in-mold hot cutting of plastic parts, in-mold hot cutting of boron steel sheets, and variable edge cutting of motor pen-shaped iron cores have created a new era of integrated mold manufacturing units. Mold products continue to develop in the direction of large, sophisticated, high performance, integrated manufacturing units.
2. The commercial Internet extends to the mold and its industrial chain. At present, many mold processing equipment companies have also docked the Internet, actively creating a "mold manufacturing + Internet" model, effectively promoting the transformation and upgrading of the mold industry.
3, 3D printing is widely used in mold manufacturing. The production of mold cavities in 3D printing applications is a new trend in the development of cavity molds. The metal additive-reduced material combination manufacturing technology is an important direction in the field of 3D printing. At present, high-precision manufacturing of complex metal parts is realized by 3D layer-by-layer additive forming, combined with high-speed milling of layer thickness profile and material reduction.
4. The intelligence of the mold. At present, in the plastic mold and die-casting mold industry, molds for intelligent control of pressure, temperature, flow rate and cooling process of the mold cavity have appeared. In addition, the intelligence of mold processing equipment is also rapidly promoting the intelligent manufacturing of molds.
5. The emergence and optimization of lightweight new materials and large plastic molds. With the development of lightweight vehicles, lightweight new materials are emerging one after another. Domestic mold companies have begun to cope with this change, and the development of lightweight new materials automotive cover molds and large composite molds has been launched.
6. The maturity of large-scale progressive die technology, high speed and high reliability have become important features of precision progressive die. At present, large-scale progressive stamping parts abound, the parts are getting larger and larger, and the shape is more and more complicated, showing that the large-scale progressive die technology has entered a mature stage. The high-precision precision progressive die has higher and higher requirements for the stability and reliability of production, and has become an important means of competition for mold manufacturing enterprises. Obviously, the mold design and manufacturing technology of super large-sized formed parts and small ultra-precision parts has become a hot spot for mold companies.
7. The standard parts of the mold tend to be refined. In recent years, with the improvement of mold types and requirements, mold standard parts have become an important condition for mold enterprises to participate in international competition. The variety and classification are the main trends of current mold standard parts. There are more and more traditional standard parts, and the quality requirements are getting higher and higher. New functional structure standard units and standard parts with more manufacturing flexibility are also becoming more and more important, becoming a new direction for new technologies and innovations to enhance competitiveness.

It can be seen from the above that China's mold technology has developed to another new stage, but in order to achieve greater breakthroughs, it is necessary to continue to optimize travel.
