Photochemical Machining
We continue to advance technology in the medical device industry and photochemical machining is one area.
Sometimes the right solutions for medical challenges rely on long-standing, unique methods that have been implemented and innovated for years.
Resonetics has been producing unprecedented photochemically machined components for over 50 years and is widely recognized as a leader in precision etching of thin materials.
These photochemical etching techniques use a strategic combination of exclusively designed equipment. Resonetics’ in-house methods allow your medical devices to benefit from their custom resist, online process control, and enhanced metrology capabilities to produce high volume products with leading-edge tolerances and unprecedented results in both through-etch and partial-etch processes.
