Design Fundamentals
Here are some considerations to take into account when designing your product.

1. Operating Environment - Will the product be exposed to high and/or low temperatures? Will the product be subject to corrosion?
2. Life Expectancy - How many cycles is the spring expected to perform? What is the cycle frequency?
3. Spring Load - Is there a required load and what range of deflection must be maintained?
4. Space - Is there adequate space to allow the spring to function properly? Pin or hole size.
5. Tolerances - Tolerances for machined dimensions do not apply to spring or wire/strip form manufacturing. We follow the tolerance guidelines of the Spring Manufacturers Institute (SMI). Tolerances for stampings can be closely held.
6. Burrs & Sharp Edges - Burrs can be minimized during the manufacturing process. Sharp edges are a result of the cutting operation. Removal of burrs and sharp edges can add cost.
7. Finishes - The proper selection can improve life expectancy and overall performance. The overall cost will be effected depending on the finish.
8. Quality Control Reports - We can furnish QC reports such as CpK/XR charts; PPAP runs can be quoted as an extra.

Our Sales Engineers can provide technical guidance or propose solutions to complex problems with your application. We will assure all elements of your design specifications are fulfilled.
