Mold tools

Exhibitor
Vitrum Technologies GmbH

Forming tools which are made of various metallic and non-metallic high-performance materials are used for non-isothermal glass forming. The precise production of the forming tools is crucial for achieving the highest accuracy in hot glass forming. To increase tool life, there is the option of reducing wear by applying protective coatings.
A wide range of geometric features is offered: aspherical and free-form lenses, wafer-level inserts, multi-cavity tools. For isothermal glass forming, materials with high strength and fatigue resistance are used.


The following services are offered:

Design of the forming tools:

- Complete specification of the functional glass-contacting surfaces and the machine connection

- Development of the mold temperature control strategy (cooling and heating) - for the non-isothermal mold forming

- Development of suitable scaling strategies (e.g. multi-cavity molds)

Production of the mold tools:

- Pre-machining and finishing using state-of-the-art machine technology

- Metrological characterization

Coating of the mold tools:

- Design and use of protective coating systems, e.g. based on DLC

Preparation of the mold tools: 

- At the end of their life cycle molding tools can be reconditioned and cost-effectively reused.
