Oil canning cannot be cured by coining, beating, or reshaping the metal. Instead, it must be prevented by ensuring the sidewalls are not subjected to radial compression.

Stamping high-strength steel, rather than mild steel, requires a different press system design approach. Standard presses are not designed to withstand the forces associated with HSS. A link drive can reduce the impact when the upper die touches the blank holder,and a heavier-than-normal press frame minimizes deflection.

When a quality stamped product is needed, operating as a team, communication and a solid understanding of the plan is paramount in efficiently producing a stamping die. The three critical phases of producing a capable stamping die are design, build (manufacture) and troubleshooting. Each phase is intertwined and dependent on one another. A design review is an excellent opportunity to develop a plan and review the construction and manufacturing methods that are going to be used to make the components. Ultimately, the challenge is to have gained a profit for your company and produced a stamping die of superior quality.
