Abstract
The invention relates to a method of producing glass-ceramic parts and/or glass parts by deformation of a glass-ceramic blank and/or glass blank. The invention is characterized in that forming is carried out using infrared radiation.
Claims18
A method for producing glass-ceramic parts and/or glass parts comprising:
- forming a glass-ceramic and/or glass blank using infrared radiation, wherein the infrared radiation is a short-wave infrared radiation from an infrared radiation source with a color temperature of more than 1500 K, and a portion of the infrared radiation acts directly on the glass-ceramic blank and/or glass blank, and another portion of the radiation acts indirectly on the glass-ceramic blank and/or glass blank, and wherein the portion of the radiation acting indirectly on the glass-ceramic blank and/or glass blank is more than 50% of the total radiation impinging on the surfaces of the glass-ceramic blank and/or glass blank.
