Stringent Process Control

From Material to Shipping

Our process control mechanisms help prevent scrap, containment, and rework situations.

Automated material inspection and traceability – individual material blanks are QR-coded with specifications, purchase order, heat number, and serial number immediately upon arrival. This data is transferred from the QR Code to the RFID tag and tracked throughout the manufacturing process.

Extensive use of in-process measurement and data acquisition.

Strict control of source documents, tooling, work holding, and work instructions.

Automated in-process CMM measurement and surface testing.

Routine, automated machine health checking.
