Our Company

Arnold's employees take pride in their ability to develop a customer's product from an idea to a quality finished part or machine assembly. We also have a trained staff of drafting personnel equipped with state-of-the-art CAD systems who willingly work with our customers to fulfill their developmental needs.

To ensure the conformance of production of these parts and assemblies, our inspection department has been continually updated with the most current inspection equipment available.
Using electronic gauging equipment capable of charting roundness and recording diameter sizes, Arnold provides upon request documentation of tested samples.
Additional equipment enables Arnold employees to measure diameters to within .00002 inch.
