GP-Series

Next Generation Pressing

WALTEC’s GP-Series represents the next generation of fully automated glass pressing. Powered by advanced ESERVO technology, these production lines combine precise, repeatable forming with significantly reduced energy consumption.

Flexible configurations for single, double, triple and quadro gob production support a wide range of products – from tableware and stemware to technical glass, cookware, insulators and glass blocks. Intelligent process control, high-speed handling and integrated fire polishing ensure efficient workflows from gob feeding to annealing.

Engineered for high output, consistent quality and long-term reliability in demanding glass manufacturing environments – 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.

GP-Series – Production Lines

Powered by industry-leading ESERVO technology next generation E-Press

WALTEC is a leading manufacturer of fully automated, electronically controlled glass forming lines – from feeder to annealing lehr – as well as complete turnkey projects. Surface quality is a defining characteristic of glassware. After forming, fire polishing refines the glass surface and treats mould parting lines through controlled flame exposure.

Improving hot-end forming operations is our key challenge. We achieve this through sustainable technologies, reliable production lines, and innovative components.

All our production lines comply with tomorrow's economic and environmental requirements for sustainable glass manufacturing.

Key Benefits

Improved resource efficiency
Reduced energy consumption
