Main data

• BDF automatic weight control system trough the position control of the plunger mechanism
• Position control of the plunger mechanisms
• Capacitive linear transducer
• Complete plunger stroke control
• Available for SG-DG-TG-QG on all machines type
• Glass weight controlled by height regulation of revolving tube
• DG – TG – QG gobs balance through individual refractory plunger height control

Benefits

• Automatic regulation of the gob weight
• Reduction mechanical interventions of the operators
• Qualitative and quantitative improvement of the production
• Stability of the gob weight
• Defects reduction on the finish of the articles
• Best thermal stability of the forehearth, machine and production
• The interaction with the inductive transducers facilitates and speedup the set-up of the mechanism
• Increased speed and production quality thanks to the control of the operating air with proportional valve (optional)

Technical features

• Fast change Plunger Mechanism thanks to the “wireless data transmission and inductive transformer” between plunger mechanism and foot plate
• Linear transducer made in heavy-duty and high stability materials (ceramic)
• New wireless technology on transmission serial data (RS485) with high frequency (27MHz) and high speed (1Mb/sec) transceiver
• New inductive technology on the power transmission between plunger foot and sensor on the plunger cylinder
• Possibility to up-grade existing machines with standard plunger mechanisms
