China's foundry industry is facing the pressure of transformation and upgrading, by 2020 foundry Enterprises will be reduced to less than 15,000. 3D Printing will play its unique role in it.
3D printing can ensure that the overall quality of the mold is better than the traditional casting method, greatly improve the casting yield, surface finish, reduce casting defects, scrap rate, thus saving more costs. 3D Printing equipment is the use of additive manufacturing technology, that is, the use of materials "layered manufacturing, layers by layer accumulation" method of manufacturing solid parts, which combines computer graphics processing, digital information control, laser technology, electromechanical technology and material technology and other high-tech advantages, can be used to improve product manufacturing links,
Dramatically shorten R & amp; d and production processes.
Among the many 3D printing technology, three-dimensional printing technology (referred to as 3DP technology) has the characteristics of fast forming speed, low price of forming materials, and the forming process does not need support, redundant powder material removal is convenient, especially suitable for the complex prototype of the inner cavity, the most suitable for the combination with the casting process, the realization of industrial applications. Many enterprises can import high-efficiency large 3D printing equipment, the development of 3D printing technology in the industrial application of casting research.
Equipment using 3DP process, mainly used for casting sand type of direct printing forming, so that the traditional casting mold manufacturing, modeling, core making, type, such as 4 processes all by 3D printing a process instead.
Traditional casting method is not only time consuming labor, but also high scrap rate, it is difficult to ensure the integrity of the shape and compactness.
Modern 3D printing technology can ensure that the mold shape is exactly the same, smooth appearance, high density, appearance and overall quality is better than the traditional casting method, greatly improve the casting yield, surface finish, reduce the casting defects, scrap rate, thus saving more costs. Also with the more difficult, complex shape of the larger castings engine cylinder block as an example, you can see the appearance of the finished product clean, reduce the sand clamping, sand hole and other castings problems.
