Low‑Pressure Casting FAQ
What materials are best for low‑pressure casting?
Aluminum alloys such as A356 and A357 are ideally suited for low‑pressure casting because of their excellent strength, flow, and corrosion resistance. Our engineers will recommend the best alloy for your component’s performance and environment.
Can you heat‑treat low‑pressure cast parts?
Yes. The low porosity and high‑density microstructure achieved through low‑pressure casting allow for reliable heat treatment, including T5 and T6 tempers for increased hardness and strength.
What are the key design considerations?
Optimal DFM principles include consistent wall thickness, draft angles of 2–3°, and smooth transitions. Gate placement and controlled filling are critical to ensure uniform quality. Our engineers handle these parameters during design validation.
What factors influence low‑pressure casting cost?
Costs depend on tooling complexity, material selection, part size and weight, production volume, and any post‑processing such as CNC machining or heat treatment. We provide detailed DFM analysis before quotation.
