Pacific Manufacturing has been a fixture in the San Diego machining community for over 50 years and our focus has always been in three key areas: Quality, Timeliness, and Customer Service. Our longevity in the very competitive San Diego manufacturing market is proof of our commitment to these values.

We are outfitted with updated machinery that enables us to keep our prices and lead-times low. Our in-house welding shop eliminates the need to outsource this service which can add extra time and cost. Additionally, PMI possesses calibrated load-testing rigs that can perform stress tests on tools, parts and fixtures and certify with certainty the integrity of each.

In the time we have been in business we’ve fostered long-lasting, quality relationships with business partners all across America. Our network of service providers and product suppliers offer us a plethora of choices that are unmatched in the local industry.

As Pacific Manufacturing, Inc. looks forward to celebrating 50 years as a fixture and contributor to the San Diego business community, we are committed to continuing to partner with other local businesses as well as national and international entities.

When customers realize a company has attained AS9100 , they can purchase parts or products with a great degree of confidence

In November of 2013, PMI was awarded the very first San Diego Workforce Improvement Bureau (WIB) Grant, to assist in facilitating their ISO and AS9100 certification. Over the next year, PMI refined its existing quality policies and practices and in December of 2014, they received their ISO 9001:2008 and AS9100C certification from DNV.

As standard practice our company keeps meticulous records of conformance for all raw material, processing services and load-tested purchased goods in addition to certifications for all parts load tested in-house.

All of our welders are certified in-house against the company's PQR's and maintain meticulous records of work completed to facilitate in the renewing of welding certificates and to ensure compliance with our customer's rigorous supplier requirements.
