Inspection And Quality Control Procedures In Our CNC Machine Shop

Our quality process is run through the whole projects from RFQs to production shipment.

Two independent reviews of the purchase order is where our QA begins, determining that there are no questions or conflicts regarding dimensions, material, quantities, or delivery dates.

Then reviewed by experienced personnel involved in the set up and production and individual inspection reports are made for each operation that is required to produce the part.

All special quality needs and instructions are documented and inspection intervals are then assigned based on tolerances, quantities or complexity of the part.

We minimize risk by tracking and analyzing every step of our manufacturing process to minimize part to part variation, and assure consistent, reliable quality for every part, every time.
