Tri-State Manufacturing was established more than 20 years ago with a few Davenport Screw Machines and Swiss Screw Machines to manufacture electronic components. Over the years, Tri-State Manufacturing has added additional equipment to make precision aircraft, fastener, and commercial products.

Producers and distributors of aerospace, medical device, electronic and other industrial, military and commercial products turn to Tri-State Manufacturing for custom parts that meet exacting specifications. Tri-State’s operations incorporate precision, highly productive equipment with proven processes to deliver what our customers require, on time, always. We do turning, slotting, tapping, threading, drilling, milling and other operations to create what our customers need. Tri-State Manufacturing complies with ISO9001:2008 quality standards and many of our customers require MIL SPEC compliance as well. We serve customers all over the United States with a concentration in Southern California. Typical parts range from simple spacers and stand-offs to complex aerospace grommets and internally & externally threaded blind bolts. Materials include stainless steel, brass, aluminum, copper, titanium, high strength alloys and plastics in addition to common carbon steels.

The guiding principle of our company is to always say what we will do and do what we say. This applies to pricing, delivery schedules, quality and communication. The best evidence that we follow through on this promise is found in the comments we hear from our customers. A number of our customers perform regular audits of our quality processes, our delivery performance, and our product quality. We will be pleased to provide references.

Also, we recently examined our competitive record and found that we win just over 87% of the time when work is put out to bid. This is solid affirmation that our cost structure and efficiencies are benefits for our customers and allow them to deliver cost competitive, high quality end products in many worldwide markets.

Our Mission

Our motto is RELIABLE PRECISION and we are able to deliver on that promise by backing our dedication to quality with the necessary equipment and skills. The products we make vary tremendously in complexity, so our experience and adaptability help us quickly perform the first article and sampling inspections of everything from simple sleeves or standoffs to complex, internally and externally threaded and knurled inserts.

We maintain an inventory of calibrated and certified tools ranging from basic gauges, micrometers and calipers to digital comparators and customer supplied inspection devices.

Quality Standards

Tri State Manufacturing adheres to state-of-the-art best practices for inspecting, tracking, certifying and reporting on the work that we do. The goal is to always deliver the quality that our customers expect. We are almost always performing as a stage of our customer’s manufacturing process, and they cannot tolerate the delays and inefficiency that occur when delivered components get rejected or need rework. We are proud that out of a number of our customers who perform formal audits or reviews of our processes, many give us annual “report cards” where we receive the highest scores.

Quality Assurance

Our company is self-certified to the ISO 9001:2008 standard. This means, the inspection processes, record keeping, training and monitoring standards of ISO are employed to ensure that the products we deliver always meet the specifications and material requirements.

A number of our customers are large aerospace manufacturers who audit Tri-State to verify if we practice what we claim regarding quality and commitment to our customer’s success. We are proud to acknowledge that we not only pass these examinations, but we also receive quarterly reports on our performance where we have always maintained 100% ratings.

While process is certainly the key foundation for quality in any manufacturing operation, the attitude of the people in the organization will determine whether the process is embraced or resisted. Tri-State people understand that our success and our future are completely dependent on meeting and exceeding our customer’s expectations. They believe that our quality process is in place to make sure our customers are happy. The procedures, standards and documentation that everyone understands are viewed as helpful by eliminating confusion, answering questions and serving as the “customer’s voice” during our daily production operations. Tri-State is fortunate to have a stable, long-term employee base.
