Product Details


Although it is the third most commonly-used metal in the world, the softness and malleability of copper make it difficult for many in our industry to work with. Fortunately, Portland Precision Manufacturing Company has many years’ experience in machining copper, and can produce tight tolerance, high precision copper parts that match your exact design specifications.

A highly skilled staff and advanced equipment allow us to deliver machined copper parts with tolerances of ±0.0005” or better. Copper CNC machining technology ensures perfect repeatability, from the first part to the last, in any quantity, whether you need a single prototype component or high volume production runs with tens of thousands of pieces. Anything you require, from the simplest parts to the most intricate, can be machined to match your exact specifications.

Industry Served

We provide the CNC machining for stainless steel parts used in the following industries:

• Automotive. As we know so far, auto vehicles can not exist without our product;

• Aerospace. We have not found any other material based aircraft;

• Industrial. Nothing more to talk;

• Military. Wooden bullet? No way.

• Pharmaceutical. Well, maybe...

• Mining. Just minning without metal tools, try first and cry later.

• Construction. Caveman's buildings were non-metal, and they died off;

• Transportation. Wooden ships had already been weed out. So, you have no choice.
