Greystone is known for its custom designed tooling, engineered to provide exceptional thickness control to hold tight dimensional tolerances in high-volume production. All tooling is custom designed and fabricated in-house to accommodate the most difficult geometries. The Greystone Medical engineering teams experience working with these geometries and tolerances spans over 80 years and several billion components of various sizes. Greystone is able to process any quantity of parts from a 1 piece prototype to a million piece production order.

When faced with rigorous challenges and testing requirements, Greystone welcomes the opportunity to design an innovative process or coating to meet customer needs. Challenges met range from developing a coating which allows for corrosion testing in excess of 1,000 autoclave cycles to developing medical chrome plating processes increasing part life well over a billion operations. All of this is capable through Greystone’s significant engineering resources dedicated to running samples, developing and validating prototype processes, and scaling those processes to full production.
