Beryllium Copper Photo Etching Project for Oil Industry

Photo etched beryllium copper formed rings

VACCO’s Multi-Fab group provides precision photo etching for a variety of materials, including beryllium copper. Recently, one of our oil industry customers needed high quality services for photochemical milling of beryllium copper. This product solution required the use of VACCO’s photo chemical etch line and pneumatic forming press equipment. An example of how VACCO combines its etching services with many other value added capabilities.

The products shown are formed support rings etched from high-strength beryllium copper C172, known for its high thermal conductivity. The finished units measured ~4.5” overall with a thickness of 0.005″. Our photo etching process maintained dimensional tolerances of ± 0.0005” and formed tolerances of ± 0.003”.

VACCO’s expertise, superior materials, and inspection systems, including Statistical Process Control (SPC), resulting in high-quality photoetched formed rings. Additional details for the beryllium copper photo etching project are listed in the table below. Contact us directly to learn more.
