Quality Control

AS9100:D Certified, ISO 9001:2015 Certified and Itar Registered

First and foremost is quality. Portland Precision Manufacturing Company’s commitment to high quality precision machining starts when your purchase order is received and ends only when your CNC machined parts and components are delivered, inspected, and found to be in compliance.

Because we know the success of your product depends on the tight tolerance of your design, strict quality controls are in effect throughout Portland Precision’s CNC machining and manufacturing processes. Our dedicated quality control staff and state-of-the-art equipment ensure that your parts meet all your dimensional requirements.

We offer complete, customer-driven inspection of parts and components, whether you need 100% part inspection on every order or just first article quality checks.

Portland Precision also offers quality inspection services for parts made by other manufacturers. No matter who made your parts, we can check them against your design specs for proper precision and dimensional tolerances.

At Portland Precision Manufacturing Company, quality is reflected in everything we do. Contact us today to learn more about our quality control processes.
