Complete retrofit of a forming press in three weeks

Gräbener, Germany, have undertaken a complete retrofit of a forming press within just three weeks. The company carried out this task at Erndtebrücker Eisenwerk GmbH & Co KG (EEW), a company that has been using a pipe forming press for just over 10 years. A similar Gräbener pipe forming press installed at EEW’s Korean subsidiary has proven to be considerably quicker with more precise bending results. Due to the booming nature of the pipe market, a swift retrofit was essential to the operational stability of the plant. fi The pipe forming press installed at EEW’s Korean subsidiary

The retrofit involved installation of the deflection compensation and reworking of the lower tool, installation of the plate and pipe handling system, complete retrofit to the hydraulics concept and a completely new electric system and control. Each pipe duct, connection to the cylinders, and the entire piping was engineered and drawn by means of Catia V5 (3D CAD program) and pre-installed at the Gräbener works. The construction, installation and start-up of the new system had to be planned. Prior to this, segments of the old press also had to be dismantled. Gräbener‘s time limit for the dismantling and cleaning of the remaining machine parts and foundation was one week, with two weeks for installation and start-up. The usual period for the installation and start-up of pipe forming presses is four to five weeks.

The entire retrofit was carried out between December 2006 and January 2007. The first pipe left the ‘new’ machine on January 05, 2007.

Reduced consumption costs with economical marking systems

Leibinger,

Germany,

manufactures the JET2SE range of ink- jet printers, which are used in a range of industries, including automotive and pharmaceutical, for the labelling of packaging, and the marking of metal, plastics, glass and coated surfaces.

The company has developed ECOsolv, a new solvent recovery system capable of reducing the consumption of solvents in printing by up to 50 per cent. ECOsolv is designed to complement the features of the Leibinger JET2SE range. Leibinger ink-jet printers use the continuous ink-jet principle for fast, non-contact printing. The JET2SE series also features a unique nozzle seal, which ensures an ‘instant start’ at the push of a button, even after long standstill periods. › The JET2SE range of ink-jet printers
