Appliance stamper draws on magnetic die clamping to accelerate its uptime

May 5, 2010

By:

In the home appliance industry, designs are constantly updating to meet consumer tastes and changing market demands. For the stamping supplier forming a new bracket for a new design, high production volumes necessitated tripling the number of shifts. But tripling the number of shifts increased labor costs, as well as utility and material delivery costs. The stamper decreased the labor hours to resume a single-shift operation by implementing quick die change and magnetic die clamping.

Mild steel to HSS: Not just a spec change - Part II

November 20, 2009

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.

Design, build, troubleshoot

October 8, 2009

By:

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.
