Glass forming: efficiently forming high-precision glass optics

High-precision glass optics with complex shapes are key components of many new products used in a number of industrial sectors. For example, demand for complex yet cost-effective components made of glass is growing in lighting technology, the automotive industry, laser technology and renewable energies.

However, the trend toward increasingly complex geometries coupled with rising cost pressure is presenting companies with major challenges. At Fraunhofer IPT, we research different types of forming for the efficient production of complex geometries. In addition, we are active in the fields of simulation and tool coating.


Non-isothermal glass molding

In non-isothermal glass molding, which is suitable for mass production, glass blanks that have been heated in advance are formed under pressure.

Material characterization

We analyze the properties of materials such as glass, plastic and metal using state-of-the-art equipment.

Precision molding

Precision molding allows different types of glass to be shaped with high precision and given different structures and functions in a single process step without the need for reworking.


Coating of tools for glass forming

Tools for glass forming must be provided with high-performance coatings for wear protection.

Forming thin glass

Thin glass can be formed by vacuum deep drawing, gravity lowering and vacuum assisted lowering and used for a wide range of applications.

Glass forming to wafer scale

Many optics in one step: High quantities of glass optics can be produced quickly on one wafer with a high degree of accuracy.

Simulation of glass forming processes

In order to know in advance which inaccuracies can occur in the process, we simulate glass forming processes and make precise predictions about quality.
