Charmilles to Host Extrusion Tooling Seminar in United States

Charmilles will host a two-day extrusion-tooling seminar, October 22-23, at its North American headquarters in Lincolnshire, Illinois, USA. The two-day seminar will be delivered by Dave Friedwald, a designer of complex extrusion dies and sizers.

The first day of the seminar addresses vacuum sizing. Attendees will learn how to design, manufacture and use a fast cooling vacuum sizer that cools plastic profiles 540 times faster than water. In addition, they will learn how to choose the right vacuum pump, and how to taper each sizer for specific tolerances and materials.

Day two of the seminar focuses on dies, and will address the advantages of using sizers, design technologies to maximize wire EDMs for adapters and dies, hollow profile tooling, vinyl profiles, as well as troubleshooting pitfalls. Friedwald will also instruct participants how to eliminate sink marks in plastic profile.

“This seminar focuses on hands-on learning,” says Gisbert Ledvon, marketing manager for Charmilles. “We chose Dave as our presenter not only because of his expertise in the extrusion die field, but because the application of his techniques have been successfully applied to manufacturing processes worldwide, and saved many companies time and money.”

Friedwald spent several years working at extrusion firms before he and a partner started a new business in which they developed a number of machines that are currently used in the extrusion industry, including vacuum tanks and cutters. Friedwald has also operated a wire EDM shop. He started his own consulting and design company, Extrusion Die Technologies in 1985 and delivers seminars regularly to companies in the United States.

These seminars can be attended independently, but are most effective when attended in succession as part of a comprehensive two-day event.
