With the maturity of 3D printing technology in China, the application of 3D printing equipment in the machinery manufacturing industry is also deeply rooted in the people's mind, with obvious effect. It used to take two months from the design drawing to the model. Now through the introduction of new technology and new equipment, the cycle only takes a few days, greatly improving the design efficiency and greatly improving the research and development of cone crusher. 3D printing technology is introduced to design product mould and shorten product delivery cycle.
