The emergence of 3D printing technology has certain advantages in additive manufacturing. At present, 3DP technology has a wide range of application prospects in the field of sand casting.
First of all, the use of 3DP technology to print sand, instead of manual operation, all the molding process is carried out in a relatively closed box, the printing process will not appear the phenomenon of dust, reducing the emissions to the environment, and significantly improve the labor environment.
Secondly, compared with traditional casting, 3D printing technology omits the link of making molds, improving efficiency and saving production costs.
Third, 3D printing technology can improve product size accuracy and enhance product quality.
Fourth, 3D printing technology provides sufficient flexibility for product design. Since 3D printed sand patterns are not constrained by the size and shape of the product, the parameters can be changed at any time during the production of the product for local or overall correction, enhancing the efficiency of product development and verification.
Applications
Beijing Longyuan Auto Forming System Co., Ltd., a well-known 3D printing manufacturing service provider in China, is a new energy vehicle frame manufactured by a large Chinese car company. It adopts a lightweight design and has a complex structure. , There are many small structures, the weight of the casting is less than 5KG, and the casting material is aluminum alloy. Longyuan AFS uses quartz sand material, prints sand molds through AFS-J1600 equipment, replaces traditional steel molds, and then delivers finished parts after casting. The production cycle of the frame is 1/5 of the traditional steel mold casting time, reducing research and development costs and time.
The product has the characteristics of complex structure and fine structure, and the casting material is aluminum alloy. Longyuan AFS uses quartz sand material, prints sand mold by AFS-J1600 equipment, and then after casting, the finished parts can be delivered. The frame is a small batch trial production, and the production cycle is 60 days to complete 30 pieces of fast cylinder head production, which significantly reduces the R&D cost and time.
The application of 3DP sand printing technology simplifies the molding process, significantly shortens the production cycle, reduces the casting manufacturing cost, effectively improves the efficiency of new product development, and can be widely applied in the field of complex structure, high quality requirements, and single-piece small batch casting manufacturing.
