The origin history of cemented carbide molds Cemented carbide molds are known as the "mother of industry" and occupy a very important position in modern production. How did the molds come about? When did it happen?
(1) The development of social productivity provides a social foundation for the production of molds. The use of molds is to replicate objects of the same shape and improve the efficiency and quality of production. One of the founders of Marxism, German philosopher, thinker, and revolutionary Engels once said: "Once society has technical needs, this need will push science forward better than ten universities." When society At a certain stage of development, people have the need to use the same items in large quantities. After having the corresponding technology and tools, the mold will be produced naturally.
(2) The discovery and use of copper provided a material basis for the production of cemented carbide molds. Some scholars believe that the production of real molds should be in the Bronze Age, 5000 to 7000 years ago, and it was a production of copper as raw materials. The era of life tools and weapons, such as bronze mirrors, bronze pots, and bronze swords. At that time, the basic conditions for the production of cemented carbide molds were already available, such as metallurgical technology, mass production, and processing workshops. However, mold production at that time was still in its infancy, far from mature
