摘要： The invention relates to a method for forming a glass item, in particular a three-dimensionally formed flat glass item, wherein the following steps are carried out: arranging a flat formation of glass, for example a flat glass pane of homogeneous thickness or a flat glass pane of inhomogeneous thickness or a preformed flat glass pane blank or liquid two-dimensionally spread glass, between a mould plunger and a melt of liquid metal, in particular tin; tempering of at least one part to be formed of the flat formation of glass to a forming temperature of the glass at which the glass has a viscosity in the range from 10 Pas to 106.5 Pas, preferably in the range from 10 Pas to 104 Pas and particularly preferably in the range from 10 Pas to 103 Pas; forming the flat formation of glass by moving the mould plunger and a surface of the molten metal towards each other, preferably by means of at least one linear movement, for example by means of a linear motor or servomotor, so that the flat formation of glass is pressurised either by the mould plunger on the one hand and by the molten metal on the other hand and is formed by the pressurisation on both sides and/or by suctioning and conforming the flat formation of glass onto the mould plunger; cooling the formed flat formation of glass to a handling temperature below the forming temperature at which the glass has a viscosity of ≥107 Pas; and demoulding the cooled flat formation; as well as a device for carrying out the method and a use of a molten metal for carrying out the method.

The multiple mold (42) includes a frame (48) that defines at least sections of a receiving volume (50) for the at least two powder blanks. Additionally provided is a separating element (52) which is disposed within the receiving volume (50) and divides the receiving volume (50) into at least two subvolumes, each of which is designed to accommodate one of the at least two powder blanks. Also described are the use of the multiple mold (42) for production of a glass-ceramic blank for dental purposes, a compression apparatus and a continuous system for production of glass-ceramic blanks for dental purposes.

摘要： A method for further processing of a glass tube semi-finished product includes: providing the glass tube semi-finished product, along with tube-specific data for the glass tube semi-finished product; reading the tube-specific data for the glass tube semi-finished product; and further processing of the glass tube semi-finished product including a step of thermal forming carried out at least in sections. At least one process parameter during the further processing of the glass tube semi-finished product including the step of thermal forming carried out at least in sections is controlled as a function of the tube-specific data for the glass tube semi-finished product. In this way, the further processing can be matched more efficiently to the particular characteristics of a glass tube semi-finished product to be processed or a particular subsection thereof, and the relevant characteristics of the particular glass tube semi-finished product do not need to be measured again.

摘要： Disclosed herein is an apparatus for manufacturing a megapixel multi-focus lens. The lens manufacturing apparatus of the present invention includes a loading means for supplying a mold body, in which a blank, interposed between upper and lower molds, is placed, to a forming position, a compression-forming means, which preheats, compresses and cools the supplied mold body such that the blank is formed into a multi-focus lens having an aspherical surface, and a discharge means, which discharges the multi-focus lens formed by the compression-forming means. Therefore, processes from loading to discharging can be automated, so that the productivity of the apparatus for manufacturing the multi-focus lens can be markedly enhanced. Furthermore, because the lens manufacturing apparatus is covered with a cabinet, a superior appearance thereof is ensured. In addition, because various electric components for controlling the compression-forming means are provided in the cabinet, it is not necessary to separately install electrical control parts for mechanical parts.
