The Pinnacle process

Customers from leading medical, aerospace, information and communications technology, energy, and entertainment companies come to Pinnacle Precision because they’ve experienced a new level of precision. 

Our teams boast decades of experience, working with product sizes ranging from inches to yards and a broad range of sheet metal alloys and finishes. 

Each project that comes into Pinnacle’s Southern California headquarters receives the highest level of attention. Our Customer Support team excels in translating customer needs into actionable plans for our Technical, Production, and Quality Assurance teams. 

Our manufacturing experts utilize CNC laser cutting and punch presses for precise sheets that are then delivered to our machining, forming, welding, and finishing departments. From there, we help our customers with assembly, hardware installation, and seal applications before Pinnacle’s quality assurance team carefully looks at the final product. 

The difference between Pinnacle and any other company is our team-forward integrated approach and solutions-first mentality. We look forward to proving our promise to you.
