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.

摘要： A method for fabricating a molding tool for mold glass optical elements therewith is taught. The method comprises the steps of figuring the molding tool to have a predetermined mold surface; applying an attenuating coating to the predetermined mold surface; implanting metal ions through the attenuating coating and into the predetermined mold surface; and removing the attenuating coating leaving the predetermined mold surface with metal ions implanted therein. The method of fabrication allows for the molding tool made therewith to be used for molding optical elements from eco-glasses such as titania at high temperatures without generating adverse surface chemistry effects in the molded element.

摘要： A mold construction is provided having a layered configuration including a substrate or mold core preferably of ampcoloy, an intermediate or primer coat preferably of electroless nickel, and an outer mold surface layer made of a high strength metal preferably of titanium. The mold construction is particularly advantageous for use in molding glass objects. The electroless nickel undercoat or primer coat serve to adhere the softer ampcoloy substrate to the high strength outer layer of titanium alloy. The electroless nickel also provides some elasticity for the outer layer of titanium alloy layer to reduce cracking and flaking of the titanium alloy. The layer of titanium alloy provides good strength and durability to withstand abrasive contact with the molten glass, while the ampcoloy still facilitates high thermal conductivity for reducing mold cycle times.

摘要： Precision glass molds are described, which are formed by coating a mold made from high purity, fme grain sized graphite, with a coating including titanium. In various implementations, the titanium coating is overcoated with yttria (Y2O3) to provide a high precision glass mold of superior performance character. The resultant glass molds can be used to form glass articles having a highly smooth finish, for high precision applications such as consumer electronic device applications, medical instruments, and optical devices. The use of high purity, fme grain size graphite allows molds to be machined at low cost, thereby eliminating the need to fabricate a metal mold that must be coated with multiple layers including metal diffusion barrier layers to meet operational requirements for such precision applications.

摘要： A method for treating a mold includes grinding an outer metal surface of a mold body of the mold with a first material; lapping the outer metal surface after the grinding with a second material that is finer than the first material; and polishing the outer metal surface after the lapping to achieve an average surface roughness (Ra) less than or equal to about 0.15 μm and a waviness height (Wa) less than or equal to about 100 nm. A mold for shaping glass-based material can include a mold body having an outer metal surface, wherein the outer metal surface has an average surface roughness (Ra) less than or equal to about 0.15 μm and a waviness height (Wa) less than or equal to about 100 nm.
