Nitinol Components

Nitinol coils and wireforms offer specific properties which can be superior to stainless steel in certain cases.

Its unique elastic, shape memory properties allow for the material to return to various shapes when reacting with external environment changes.

Laser Marking

In-house laser marking capabilities can add unique identifiers such as part numbers, lot numbers, descriptions, and company logos to a variety of parts.

Depth band markings for guide wires, k-wires, and pins present visual feedback to an end-user on how far a component may be inserted.
