  Press Relase: Hydroforming Press Verson GHFP 1.500
Posted by: God on Friday, November 09, 2001 - 10:11 PM
 
 
News Invitation for a Pressdemonstration by VERSON Pressentechnik

During the opening ceremony of VERSON Pressentechnik's Communication Center on September 15, 1999 one could see a Hydroforming Press developed by GRÄBENER Maschinentechnik and VERSON.
All assembly and commissioning works has been done.
Since January 2000 several customers tested this press by using their own tools.
Based on secrecy agreements, which didn't allow to show these tools and parts, Gräbener build a tool for T - parts with a diameter of 88,9 mm. This die shows all functions of the press. The actual cycle time of this part with a wall - thickness of 3,2 mm is 19 seconds.

This press can bee seen in production until April 30, 2000 at Gräbener's premisses. Arrangements for demonstrations of the Hydroforming Press can be done with Mr. Kölsch or Mrs. Hoffmann under Telephone + 49 (0) 2737 / 989 - 500 or E-mail address Versonpt@aol.com .



Targets of Development of the Control and Press
