Most of the world sees technology in the form of a finished product, such green energy, a smartphone or an advanced medical device. It is often hard to believe that most of today's technologies require little more than a microprocessor and an LCD display. But who manufactures the machines that manufacture all these processors, mobile devices electronic components?
Peninsula Spring is a proud American spring manufacturer. We supply custom springs, wire forms and precision sheet metal stampings to the computer, medical, aerospace and defense industries. We are a well-established, experienced corporation who has been providing quality parts and engineering services since 1976.
If you require high-precision, custom metal stampings, turn to Peninsula Spring. We offer over 40 years of experience to quickly, accurately and cost-effectively manufacture punched, laser-cut and photochemically etched metal parts. Peninsula Spring is an experienced manufacturer of all types of springs since 1976.
With an extensive collection of universal tooling, combined with our high precision laser cutter, Peninsula Spring is well equipped to manufacture any type of custom metal work. If tooling is required for production runs, we know how to save you valuable time and money by engineering quality not only into the parts we fabricate but also into the tooling.
Spring clips are often used to hold components by applying a consistent amount of force onto the mating part. The material type and thickness, as well as design, determine the spring clip's force, deflection capabilities and fatigue life. Regardless of the industry, spring clips are always in high demand.

Evidently, his place can't be bothered to provide a quote or even "no quote" it if they aren't interested. How do they survive?

Been working with Peninsula Spring for several years now. Service and Quality are top notch. My first experience with PS, I submitted prototypes of springs of which I needed and they worked with me to perfect the spring. I've had positive communications with PS and they have answered all my needs.

They refused to provide a quote for a simple power spring which is apparently a type of spring they produce. Response time was incredibly slow. Bad customer service all around
