We are experts in
CNC Punching
Sheet Metal
Punching sheet metal takes an equal amount of precision and skill, especially when delivering critical sheet metal parts used in the information & communications, medical, aerospace & defense, and energy industries. Both vital skills are in play when Pinnacle’s Technical and Production teams start on a project, leveraging our design and plan expertise to create detailed punch schematics and manufacturing know-how while tooling and running jobs.

how we deliver
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.
a question we get:
Why is CNC important for sheet metal punching?
Shops like Pinnacle pride themselves on delivering precision sheet metal parts used in dozens of industries. Not many places boast our decades of experience here, including several 30-plus-year veterans on our production floor.
So, why do we rely on “computer numerical control” (CNC) during our manufacturing processes? Because our
customers work in some of the most technically sensitive industries where precision equals life-saving machinery. Plus, CNC enables a faster and more accurate process while producing complex shapes and patterns.
At Pinnacle Precision, we leverage the power of technology and the experience of our Technical and Production teams to deliver a new level of precision.
