| Résumé : |
Glass is a high-performance material with properties that are indispensable for many industries. High-precision molded parts made of glass are required in the optics, chemical and medical technology industries. However, traditional glass-processing methods impose limits on parts design, especially for tiny structures. Here, injection molding offers an alternative that is also more energy-efficient, more economical and more sustainable. Glassomer and Engel are jointly tapping into this potential. |

- Novel granulate made from high-purity quartz glass
- Targeted control over surface properties
- Manufacturing process requires precision
- Parts of the highest purity and optical quality
- A collaboration with a future
- Fig. 1 : Traditional glass-manufacturing methods compared with the Glassomer process (A): grinding, polishing and lapping (B), precision glass molding (C), conventional lithography and etching processes for fabricating glass structures at wafer level (D), laser-assisted structuring and downstream etching and polishing (E)
- Fig. 2 : The various process steps from granulate to injection-molded “green” part to ready-to-use glass part, as exemplified by a perforated plate
- Fig. 3. The multi-stage manufacturing process can produce different surface finishes. As shrinkage can be calculated, a high degree of dimensional accuracy is achieved.
- Fig. 4 : The e-motion TL all-electric, tie-bar-less injection molding machine produces high-precision camera lenses from thermoplastics – and now also glass parts
- Fig. 5 : Different sample parts were produced at Glassomer. The medical technology part (top right) here served as a feasibility study. It showed that the new quartz glass material could also be processed in molds originally designed for thermoplastic injection molding
- Fig 6 : Fine structuring of glass is becoming increasingly important, for example in the field of chemical and pharmaceutical synthesis. High-precision channels can already be produced by the new process |
