Invae 36 is very similar to most grades of steels/stainless steel in terms of overall appearance. Invar can be media blasted or tumbled to achieve a multitude of surface finishes. Additionally, powder coating can be applied to achieve more matte/glossy colors.
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
The manufacturing process you select impacts part cost, lead time, achievable tolerances, material options, and how easily you can iterate…
