Function: Inject propellant into the combustion chamber in an exact proportion of mixed fuel.
Traditional Method: Different parts must be molded with precision casting, and then various pipe fittings are also welded separately. The development time takes at least 40 days, and there is a risk of welding leakage and the flow is not easy to optimize.
Additive Manufacturing (Metal 3D Printing)
- One-piece Design: Fabricate 200 parts in one piece à lightweight design.
- DfAM: The arched back is a classic example of Design for Additive Manufacturing (DfAM). Without such design, a support structure must be implemented, which complicates the production procedure and increases time cost.
- Integrated Molding: (1) Eliminate the welding procedure, for at least half the volume and weight. (2) Shortens the product development cycle by 4 times. (3) A sliding pipeline and complex internal flow channel design can be implemented.
