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.

Usually the first place stampers look to reduce cost is the labor burden per part, which leads to the inevitable pursuit of producing parts faster. The speed capability of a stamping die is determined by how fast the part physically can be produced and at what speed the tooling fails. The strength of the carrier, how high the part must be lifted, and the mechanical limits of the springs and side action cams (mandrels) limit how fast the tool can run.

In today's economy, machinery moves are on the rise. The success ofa machinery move project will be determined by the effectivemanagement of five key stages: planning, dismantling, servicing,5transportation, and installation. Do not overlook the relocationprocess as an opportunity to inspect, repair, and make modificationsto enhance the press system.

Factoring in the economics inherent in a small footprint—if a building expansion is required for a larger line, for example—a space-saving line may be the most economical option. Categories of space-saving coil feed lines, from the least expensive to the most expensive,are the paddle loop, space saving, and synchronous.
