Camber-free slitting for successful stamping

July 25, 2002

By:

For large volume parts runs, problems such as misfeeds, off-center hits and inadequate transfer webbing can cause slitting-induced strip camber. The production of camber-free slitting requires proper material selection, tooling, techniques and inspection practices.

Reinventing the wheel - Chrome plater develops automated wheel polishing process

July 25, 2002

By:

Kuntz Electroplating, a Kitchener, Ontario-based independent OEM chrome-plating supplier of automotive wheels and bumpers, the management watched as hundreds of its workers manually polished its wheels. Because this made it difficult for the company to find, train, and retain the workers it needed, it decided to develop its own automated process for wheel finishing.

Evolution of the beast

June 27, 2002

By:

This article outlines how mechanical presses are changing to meet a new marketplace. Stampers are adding extra stations to create a more complete part and stamping harder alloys. Servo-driven mechanical presses will make traditional flywheel presses obsolete because they use less energy and can be adjusted midstroke. Technological advances include real-time press monitoring, automatic die changes, and computerized troubleshooting.

What's new with multiblanking lines?

May 30, 2002

By:

Multiblanking lines are used to produce small, accurately shaped blanks directly from large coils. Modern lines can process many different types of material over a range of thicknesses, while still allowing quick changeovers and minimal maintenance. New technology is available in several key areas that limit the capacity of a typical multiblanking line, which include leveling, slitting, feeding, shearing, and stacking.
