Prototype and Low-Volume Production Processes

Armstrong RM specializes in the production of metal and plastic parts in prototype and low-volume production quantities. Our operations are designed to deliver individual parts and complete assemblies...rapidly.

Assistance: Selection & Design for Manufacturability

With so many manufacturing processes available, it is difficult to have a thorough knowledge of each, and even more challenging to understand each technique's design for manufacturing constraints. We help you to find the best process with our extensive background and knowledge in manufacturing. And, we go one step further. Armstrong RM can relieve you of the effort to modify or redesign your parts for the selected process. So, you don't have to spend time accounting for shrink, draft or "as-cast" design modifications.

Each of our processes has been proven to be excellent "bridge to production" solution. So, if you use Armstrong for your prototypes and then find that production tooling will be late, we can quickly deliver large quantities to production specifications.
