W-Series

Press-BLow Machines

WALTEC’s W-Series redefines press-blow glass production through advanced ESERVO drive technology and intelligent process control.

Five servo drives per station replace conventional pneumatic movements, delivering precise, repeatable forming while significantly reducing compressed-air consumption. Modular configurations with up to 24 stations combine high production efficiency with flexible operation and fast changeovers. Automatic Temperature Regulation and WTRACK process monitoring support stable quality, transparent production data and shorter ramp-up times.

Designed for reliable performance, lower operating costs and more sustainable glass manufacturing – engineered and made in Germany.

Feeder

Always the perfect gob – 
flexible press operations

WALTEC’s ESERVO feeder system supports single, double and triple gob production through independently operated feeding mechanisms on a single feeder head. Depending on the production mode, the individual feeders are automatically activated or parked, ensuring maximum flexibility and precise process control.

ESERVO Components

Improved sustainability – 
significant energy savings

Modernize existing glass production with WALTEC’s ESERVO retrofit solutions. Replacing conventional hydraulic and pneumatic systems with precisely controlled servo technology reduces energy and compressed-air consumption while improving process accuracy, repeatability and production efficiency.
