Development Requirements for New Energy Vehicle Subframe Prototype:

1. Material: Aluminum alloy

2. Mass production forming process: Metal mold low-pressure die casting

3. The product is large in size with thin walls and requires weight reduction optimization

4. Short development cycle and cost sensitivity

The traditional development method uses metal molds. Design changes require multiple revisions of the metal mold, which is time-consuming, labor-intensive, and costly, and significant modifications risk mold scrapping.

Using 3D printing for casting, the forming sand mold is directly obtained through sand 3D printing and is not constrained by molds. This can shorten the development cycle by 2/3 and reduce development costs by over 50%. During the development process, multiple rapid iterations can be made according to requirements, quickly producing prototypes to meet various testing needs and helping customers quickly capture the market.
