Together We Achieved
Customer Compression Spring Challenge
Our customer was using a standard coil compression spring. To reduce the amount of material needed to make the spring, the fuel filter supplier looked to us to design and manufacture a compression spring that provided the same force with centered coils that would stand square.
Master Spring Solution
Customers often come to us when they can’t find a spring vendor to make a challenging spring. In fact, our filter supply customer received several “no quotes” from numerous spring manufacturers. Within an hour of receiving the print, we designed and manufactured a working prototype compression spring with variable diameter and pitch that supported the spring’s load and reduced the number of coils and the amount of wire used in production. We delivered the prototype to the filter supplier within 24 hours of their first contact with us.
Results
By reducing the number of coils and the outside diameter of some coils, we manufactured an extreme hourglass-shaped compression spring using less wire. Since the compression springs are bowl-fed to automatically drop into the fuel canister, the compression spring must position itself in the upright position. If either cut-off end of the spring sticks up even slightly—or if any coil overlaps another coil and sticks together—the spring will puncture the canister. To prevent these issues, our team angled the spring’s cut-off ends down slightly. The coils are centered and standing up square even though there are not many coils. In addition, Master Spring developed a custom packaging solution for this customer that made assembly faster and safer. Originally, these compression springs were shipped in heavy barrels that required two assembly line workers to safely lift. Our custom packaging solutions created a system in which each shipment is packaged in custom boxes with an exact weight that one assembly worker can easily lift—saving assembly time and creating a safer work environment.
