Application Cases

SLS Selective Laser Sintered Sand 3D Printer
SANDI Technology SLS selective laser sintering sand 3D printer is suitable for one-piece molding of complex pipeline and oil pipeline structure sand mold. The precision of the printed sand mold can reach ±0.1mm and the strength can reach 4-6MPa.


SLS Selective Laser Sintering Wax 3D Printer
SANDI Technology SLS Selective Zone Laser Sintering Wax 3D Printer can rapidly mold large-size, thin-walled structure wax patterns with high molding precision and excellent surface quality.


SANDY Technology 3D printing technology empowers casting
Primary value:
1. Enhancement of new product development capabilities
-No need to open metal molds, reduce the cost of new product development and shorten the production cycle;
-Enhance the enterprise's ability to develop new products and new customers and grab orders for bulk orders.
2. Fast delivery of small quantities:
-Low-cost and high-efficiency production of small-lot products through 3D printing or a combination of 3D printing and traditional processes (outer mold: metal mold/wood mold; sand core: 3D printing).
3. Reduce process validation risk:
-Process validation before opening metal molds reduces risk of failure and mold repair time.
4. Rapid manufacturing of metal molds:
-Rapidly manufacture metal molds (aluminum molds, iron molds, etc.) through 3D casting process, which can shorten the manufacturing cycle of metal molds and reduce the manufacturing cost of 20% or more.
5. Optimize the process and improve the technical level:
-Satisfy the demand for lightweight, complex structural products, realize integrated molding, parts manufacturing into components manufacturing, help casting enterprises to enhance the level of technology, improve the added value of products, enhance the profitability of enterprises.
6. Improve material utilization:
-Improve casting material utilization and reduce resource consumption.
7. Enhance the corporate image and improve the production environment:
-Reduces labor intensity and eases recruitment challenges.
Collaborative Advantage:
As a leader and application promoter of 3D printing technology, SANDY TECH.Has received investment support from well-known funds such as Jinko Junchuang, CICC Capital, CSC Haichuang, Become Capital, Beijing New Materials Fund, SINOMACH Industry Fund, etc.The
