Facilities & Processes

NADCAP & Approved Processes

 We are NADCAP certified for Fluorescent  Penetrant Inspection (FPI), Magnetic Particle Inspection (MPI), Conventional  EDM,  fusion welding and chemical processing.

Birken Manufacturing has been certified to the most stringent quality standards in the Aerospace industry since 1998. This marks our strong commitment to continuous improvement in our quality control processes. Our registrations include sheet-metal fabrication, precision assembly, precision machining, hot and cold metal forming,fusion welding and pneumatic and hydraulic testing.

Birken’s quality policy stresses continuous  improvement.  By tracking quality issues  and determining the cause of any quality problems, we seek to institute  corrective action to assure that the issue never reoccurs.  Our employees are encouraged to assist  manufacturing and engineering by determining corrective action that will improve  manufacturing precision, efficiency and provide value and quality for our  customers.  Our quality system conforms  to existing MIL-STD specifications.
