We have been committed to helping our customers maximize their potential and achieve their goals by reducing lead times, improving quality and reducing cost for 33 years. Leading edge technology coupled with years of experience enables Sierra Pacific Machining Inc. to thrive in slack or booming economic climates.

We frequently work with engineers to help optimize your design from a manufacturability standpoint to reduce cost. We believe in demonstrating the highest level of business ethics. We do this by conducting our business with uncompromising principles and professionalism.

Sierra Pacific Machining has been in business since 1977. We are a Small Veteran Owned Business Primary Nasic Codes 332710 332721 Cage Code 5J3V1. Our commitment to our customers since our inception has been to provide the best service possible. We are proud of our on time deliveries, competitive pricing, and high quality output. In a lean manufacturing environment, even infrequent rejections cause significant disruptions in the flow of materials and parts through the system. The non value added activities associated with rejecting, dispositions, reworking or returning parts and inspection upon receipt use resources which could be better utilized for continuous improvement activities for our customers. That is why Quality is our main goal.
