ELECTRIC UNSCREWING UNITS

The electric thread unscrewing unit is a separate drive for thread demolding on injection molds. The units can be mounted on existing hydraulic or fully electric injection molding machines. For this purpose, a free core pull must be available for controlling the operating unit. The operating and control unit, which is tailored to practical applications, eliminates the need for programming with a separate PC on the injection molding machine.
