The hottest production digital mold manufacturing

The production of digital mold manufacturing led the third industrial revolution

[electromechanical news] the first industrial revolution appeared in Britain in the late 18th century and was characterized by the mechanization of the textile industry. In the following decades, the technology of using machines instead of making products by hand began to spread all over the world like a spark

the second industrial revolution began in the United States in the early 20th century, marked by the production line. Assembly line production ushered in the era of mass production

with the digitalization of production, the third major change is now in full swing. Due to the application of new materials, the promotion of new production processes, the ease of use of robots and the acquisition of new production cooperation services, a smaller amount of production will be able to achieve the effect of large-scale economy for citizens to supervise the whole process; Production is more flexible; And less labor input. This change express is poised to form a super alliance of "offline first" and "online first". Its steering wheel has almost turned around, leaving the mass manufacturing mode and heading for a more personalized production mode. And then some production jobs that were snatched by emerging markets a long time ago can be returned to developed countries

according to the research of Luo Baihui, Secretary General of the International Mold Association, the European Mold Exhibition held in Frankfurt, Germany, exhibited machines for making product prototypes; Tools and various other manufacturing equipment required for production. Old school engineers deal with lathes, drill bits, stamping machines and molding machines. These machines are still in use, but in general, there are no greasy machines that need the careful care of workers in the mold exhibition. The exhibition hall lined up is full of mechanical tools from the United States, Asia and Europe. These tools are spotless and highly automated. Most operators, men and women alike, sit in front of the computer screen. There is nowhere to find the trace of the hammer

at the latest European Mold Exhibition held in November last year, the machine publicly unveiled was a three-dimensional (3D) printer. 3D printers produce products by stacking materials layer by layer without going through the traditional processes of knocking, twisting and cutting raw materials. This is why the word "add production" is used to describe the renaming of this production process

Luo Baihui believes that this is the epitome of the future manufacturing industry. It costs thousands of dollars to make a hammer designed by yourself in today's factory. The manufacturer must first produce a mold, cast the hammer head, polish it into a suitable gloss with a machine, cut a wooden hammer handle, and then assemble all parts. A hammer made in that way is certainly too expensive to ask. If you want to produce thousands of hammers, the cost of each hammer will be cheaper due to economies of scale. However, for 3D printers, economies of scale are more irrelevant. The software of the printer can be made at will. Rausberg has completed all construction adjustments on the basis of prefabrication and can produce anything. Whether it is the production of a single product or the quantitative production allowed by 3D printers, the setup cost of the machine is unchanged

add manufacturing still needs to be improved. It has not been able to manufacture cars or iPhones, but has been used to manufacture special auto parts and customized iPhone cases. Although this is still a relatively new technology, most people may already have something made with the help of 3D printers. However, additive manufacturing is only one of the many breakthroughs leading the factory to the future; Moreover, traditional production equipment has become more intelligent and flexible. Volkswagen has invented a new production strategy called modular horizontal matrix, MQB. By standardizing the parameters of some components such as engine support points, German automakers hope to be able to produce all models of cars on the same product line. This manufacturing process will be implemented this year, but with the continuous introduction of new models in the next decade, the development of MQB will be at its peak. Finally, MQB will enable factories in the United States, Europe and China to produce any car needed by the local market according to local conditions
