What We Can Do

We offer a vast array of services in the areas of CAD design, conventional and CNC machining, CNC sheet metal punching, CNC routing, forming, CNC laser and water jet cutting, fabrication, welding, hardware & installation, assembly, and a variety of product finishing processes such as full pretreat line, powder coat, paint, and silkscreening. Whether you need a single prototype part, precision machined parts, rapid prototyping, or a large production run, you can depend on us each and every time. If you are looking for any sort of metal fabrication in Portland, Or, look no further, API and AMS have what you need.

From design assistance to the finished product, we offer all of the necessary capabilities to produce customer products in house, limiting subcontracting operations that can impede timely delivery and elevate the cost. API / AMS can deliver a complex, completed product without the need for outsourcing.

Our commitment to you is quality and service …. it’s something you can count on!
