Auto Throttle Assembly

Problem: A large engine manufacturer challenged Capitol to provide a stamped and assembled critical component used on each of their small engines. While the stamping was of no issue, the first design of the assembly process had a plastic fuel valve, requiring a separate spot welded nut and a screw for mounting it. These loose parts, presented an inventory problem resulting in slow assembly time and further inconsistencies in torqueing the screw to the nut.

The Capitol Solution…
Changing the original designed valve to a self-tapping style valve and then introducing an electric torque screwdriver to offer optimum torque consistency preventing assembly line stripping. By not having to weld the nut to the stamping we saved precious labor time and cost to the customer while providing an improved quality product.

Steering Gear

Problem: A large riding mower manufacturer asked Capitol Stampings if we could reduce lead time and machining hours that they were experiencing on a cast steering gear with the possible further benefit of cost savings.

The Capitol Solution…
Our engineers jumped on the challenge and re-designed the part as a stamping, being careful to maintain all of the critical dimensions necessary for form, fit and function. The result (as shown in the picture) proved to exceed all of the challenges. After 500 hours of rugged testing in the worst of conditions, the stamped steering gear showed no changes in dimensions. The stamped version was customer accepted, and hard tooled. The cost was reduced by $7.50 per piece. There were additional savings in shipping costs because the redesigned part is much lighter as well as warranty claims as the stamped part was more rigid and less brittle than the old cast unit, resulting in more life.
