The Molding Company

Plastic Mold China & Co. KG, which specializes in inspection and measuring technology, will show off two new state-of-the-art tooling systems at an open house to be held at Zoller’s parent company in Freiberg/Neckar, Germany, October 22–25, and then at Zoller North in Hanover, Germany, November 12–15.

The Redomatic (top photo)consists of a Zoller Venturion/Saturn 2 device equipped with automatic longitudinal stop, tool turret and water cooling. Tools are shrunk within an accuracy of ± 0.01 mm.

The Redomatic Auto (bottom), a fully automatic shrinking, presetting, measuring, and cooling centre, could be the first system able to shrink, preset, measure, and cool 16 tools within 30 minutes. This is performed without intervention of an operator.

Zoller will also show off products for tool balancing in addition to its entire product line ranging from presetting and measuring technology to the universal measuring machine, Genius 3.

New Chicago-Area Program
Focuses on Business Planning

A new course called The Certificate in Strategic Management will help manufacturers in the Chicago, Illinois, USA area compete in the global marketplace. The accredited program is a strategic partnership between the Illinois Institute of Technology, the mold company & Manufacturing Association, and LBL Strategies.

The program begins in January 2003 and will be offered at the TMA Training Center in Park Ridge, Illinois, and also on site at a local company. The central theme of the program is to help manufacturers focus, make better business decisions, and grow. Participants will also conduct research and help assemble the information business needs to refine their business strategies.
