Wittmann Battenfeld to present its new EcoPower B8X at Fakuma 2023

The company claims that the toggle
lever of the new EcoPower B8X has
been kinematically optimized. By this
move, the force required for clamp-
ing force build-up has been reduced
by 15 %, which has reduced stress on
the servo motors and consequently
led to a further reduction of the en-
ergy consumption. It also enables
a higher level of dynamism with the
result of better dry cycle times. The
