The GLA should ensure the positioning of the nozzle plugs in the casting launder and thus regulates the aluminum flow in the molds. A plug is attached to the arm to control the incoming flow of aluminum.

It consists of the following electrical components:

  • Step motor
  • Linear position sensor
  • Limit switches


An external electronic control board (ASM or GMC) is used to control the stepper motor. It provides automatic management of the engine in case of emergency stop. The motor can be controlled by a stream of pulses or digital inputs (speed and direction).

In conjunction with the GLS (GAP level sensor) the GLA provide a perfect regulation of the metal level in the molds.
