Different solutions for the slipping device:

  • Hydraulique solution, pressure around the casing is assured thanks to cylinders, pressure applied can be easily adjusted. Very safe and reliable solution for large electrode.

  • Air pillows solution, are used to apply pressure around the electrode. Very easy to use and reliable solution. 





After more than 10 years of R&D and industrial tests, we can now offer you a new solution for the casting and crushing process that will improve your economical performance and your environmental footprint.
With rotating or vibrating casting machine equipped with cooled COFOR® forged copper plate, we can provide a solution to cast your alloys from 10 to 100 mm thickness, with huge improvements on production quality and reduction of fines generation (more than 50% reduction). 
This machine will also decrease the handling and time required between the tapping and the packing operations.
