Mould Technology Turning heads with all-electric stack-turning technology

Editor: Eric Culp

Since the 1996 launch of its stack turning technology, Foboha says it has installed 400 of these production systems. Now the toolmaker has added an all-electric version.

As all-electric injection moulding machines increasingly become the market standard, Foboha said its engineers have been searching for solutions on how to make stack-turning and cube moulds without hydraulic drives. One special challenge was figuring out how to integrate the necessary servo drives into the mould. The company said it has found a solution has been consistently applying it. All drives (axes) of the all-electric stack-turning mould – from the ejector to the reversing unit right though to the handling unit – are fitted with electric motors. The company said it planned to show a working model of the first such cube mould at Fakuma 2012 in Friedrichshafen, Germany, on 16 - 20 October.
