BOY 25 E Injection molding machine

Well-proven design - new drive technology

The BOY 25 E is based on a well proven design. Since 1968, more than 25,000 machines of this series have been delivered.

Significant innovation is the increase to 27.5 tons clamping force and the possibility of a differential injection, which provides increased injection speeds. Travel speeds and improved dynamics could be achieved through further optimizations.


The BOY 25 E is characterized by highest precision and reliability. With a footprint of 2,805 in², the extremely compact injection molding machine is simple, clear and economically designed. The cantivelered clamping unit features easy access and room for numerous options including automated systems.

Six different sizes of injection units combined with seven different screw diameters offer a wide range of individual equipment options.
