Close Tolerances Without Secondary Machining

The investment casting process fulfilled the tight specifications with close tolerances without secondary machining, reducing the overall manufacturing costs.

Two major advantages of Shelmet precision investment casting are the ability to naturally manage what other metal casting processes cant:

1. Difficult external configurations
2. Very close tolerances

The disposable biopsy grate shown here required a perfectly crafted grate with an absolutely level surface to accommodate microscopic cutting of tissue samples.

The 876 silicon bronze offered a high degree of hardness and resistance to corrosion.
