Quantity

The obvious cost factor you have to consider in metal stamping is quantity. The number of parts you need to make increases the cost of your stamping. Making 15 parts will cost more than making five parts. Discuss this factor with the company you are manufacturing for before creating your estimate. A proper estimate of cost will be as close to the actual cost as possible. You should also consider the quantity of parts you are going to make over several years. Long-term quantity planning affects the tooling and material used --- two factors which affects your price in different ways.
Material
-
The material you use in your metal stamping also affect the cost of the final stamping job. The material used vary depending on the parts manufactured as well as the needs of your consumer. For example, stamping the exterior parts of an automobile requires high-quality steel. The steel needs to be able to resist the elements and natural wear of driving. However, the material used in stamping a metal mailbox can be considerably cheaper tin, as the mailbox won't have the problems of road wear.

Tooling
-
Higher quality material require higher quality tooling. Higher quantities of stamping also requires higher tooling as high quantities can wear down your machines and tools faster. However, higher quality tools may still break down at any point due to unforeseeable accidents, meaning your investment could have been wasted. Try to find a balance between high quality parts and in lowering the price. Buy your tools in bulk to help pass savings along to your consumers. This is especially useful in buying lower quality parts for small stamping projects.
Stamp Fixes
-
Stamp fixes are processes that fix any errors made in your stamping. The cost of stamp fixes should also be considered in your final cost estimate. Some stamps end up with a burr-side cut. A burr-side is a rough edge around stamping. This has to be fixed with a deburring process, such as tumbling or sanding. Blanking distortion is another problem that occurs during the stamping process. This is a slight bowing that makes your part slightly curved. This is not a problem for some parts but for flat parts it is a major problem. It warps the part so much that it cannot be used.
