It is a near net shape methodology which yields many benefits over other metal forming technologies.
Supreme manufactures castings ranging from a few grams (about 0.1 oz) in weight to about 15 kg (33 lb). The cross-sectional limits are typically 2.5 mm (0.1 in) to 75 mm (3.0 in). Typical tolerances are +/- 0.1 mm for the first 25 mm (0.005 in for the first inch) and +/- 0.04 mm for the each additional 10mm (0.002 in for each additional inch).
A standard surface finish is 1.3–4 micrometres (50–125 μin)
The advantages of investment casting are
Design data can be from obtained by adapting existing legacy data such as fabrication drawings, reverse engineering from prototype samples or by working with the customer to define a specification for the requirement and creating an optimal solution that exploits the benefits of the near net shape casting process. By working closely with the customer we can add significant improvements to their bottom line.
Part or assembly simplification and the associated reduction in manufacturing steps often produce attractive cost savings. We utilise a range of design methodologies to define the metal component;
Inspection and design verification reports - our CMM can produce automated reports on casting surfaces and compare dimensional deviations to the parts' CAD file. Very valuable for first off evaluation before and after machining.
