Casting solutions for defence and aerospace

Investment castings for defence applications

The defence industry requires rigorous quality control for metal components, including strict documentation at every stage of the manufacturing process. Signicast excels in this area by adhering to the most stringent standards, including NADCAP, ITAR, AS9100 and NIST. We partner with certified suppliers to ensure complete traceability and a robust, secure supply chain for our customers.

Aluminium and stainless steel castings for the defence industry

Signicast specialises in casting a variety of alloys, with expertise in aluminium and stainless steel for defence applications.

• Aluminium alloys: Offer excellent strength-to-weight ratios and thin-wall casting capabilities, making them suitable for weight-sensitive applications in aircraft and satellite equipment.
• Stainless steel: Ideal for high-strength, heat-resistant components such as projectile launchers and surface-mounted system housings for radar and other navigation technologies.

We use a range of materials, including A356, A355, 201.0 (T6) aluminium, and 300 and 400 series stainless steels, to meet the diverse needs of the defence industry.
