High-quality tooling with competitive price

Cost Versus Value

For stampers, nothing is worse than a cheaply, poorly made die. The resulting downtime an poor product quality are major profit killers.

Stampers should make no sacrifices with respect to the die’s function, regardless of the cost. If they can’t afford to buy a tool that can effectively produce the piece part, they should not attempt to produce that part.

Tool Steel Selection

Die builders need to work with their customers to determine where lower-quality tool steel or cast iron can be used. Avoid using across-the-board die standards.

Lower grades of tool steel, such as 4140 or hardenable cast iron, could be used for the remainder of the section. Because pockets would have to be milled into the larger die section, machining time would be increased somewhat, but this additional cost would be far outweighed by the tool steel cost. Using this commonsense method not only reduces die cost, but makes it easier for the die maintenance crew to do their jobs.

Die Components

Whenever possible, avoid using custom die components. These components will have to be made in a die builder’s shop, usually at a high cost and a substantial amount of time.

Instead, consider using purchased components such as cams. These components can be purchased from a variety of suppliers, and they are available in many shapes and types and serve different functions. Because the vendors make only these components, they can make these less expensively and, in some cases, more accurately than a die shop can.

Fit and Function

Avoid both overbuilding and underbuilding tooling. Working with your customers to define the necessary die geometry and construction techniques is an important first step toward reducing tooling cost without sacrificing quality.

Die don’t have to be pretty; they just have to work properly and be easily maintained. Die components such as stops or setup blocks often are unnecessarily ground on six sides, with the perimeter of a riser fully machined, and finished and polished to give them a brilliant appearance. Although grinding all of the die components makes them look great, it does nothing to increase the performance of the tool.
