Forming process of bulk glass

Isothermal and non-isothermal bulk glass forming

Glass molding is suitable for the economical production of high-precision optics in large quantities. Applications for these components can be found in innovative industries such as medical technologies, the automotive sector or sensor technologies. The geometries produced include spheres, aspheres, diffractive structures, lens arrays or free-form surfaces. A wide variety of optical glasses are suitable for this type of forming.

Compared to conventional grinding and polishing, glass molding is suitable for efficient and economical forming of semi-finished glass products. After a specific heating of the glass, the viscosity decreases so that the glass can be formed between two tools and does not require any further processing after the cooling phase. Especially when using wafer-level or multicavity approaches, molding (isothermal and non-isothermal) has enormous scaling potential.

Vitrum Technologies offers individual solutions for isothermal and non-isothermal process control for your application.
