Thermoforming method, thermoforming mold and thermoforming device for glass product
The present disclosure relates to a thermoforming method, a thermoforming mold, and a thermoforming device. The method comprises: providing a glass sheet to be processed at a softening point temperature and above; providing a thermoforming mold which comprises a male mold, a female mold arranged above the male mold and matched therewith, and a limiting block for limiting the female mold from deviate from the male mold, wherein the female mold comprises a central body module and a female mold frame surrounding the central body module and matched therewith; a first pressurizing process, wherein the central body module and the male mold are matched to press a central plane portion of the glass sheet; and a second pressurizing process, wherein the female mold frame and the male mold are matched to press a peripheral portion of the glass sheet so that the peripheral portion is bent and molded relative to the central plane portion; wherein the central plane portion is always pressed by the central body module in the second pressurizing process. The method improves the quality of a molded glass product and enhances the manufacturing yield of the glass product.
GLASS PROCESSING SYSTEM WITH VARIABLE BENDING STATION
A glass processing may include a heating station to heat glass sheets, and a bending station disposed downstream of the heating station to bend the heated glass sheets. The bending station may include first and second independent movement mechanisms configured to independently move first and second molds when the glass processing system is operated in a first mode, and to cooperate to move a third mold when the glass processing system is operated in a second mode. The system further includes a control system to control the movement mechanisms so that they operate independently when the glass processing system is operated in the first mode, and so that they operate simultaneously when the glass processing system is operated in the second mode.
METHOD AND DEVICE FOR BENDING PANES
A method for bending panes, includes providing a pane heated to bending temperature, securing the pane against a contact surface of the first bending mould, positioning a press frame for the pane in a first press frame position associated with the first bending mould, transporting the pane on the press frame to a second press frame position associated with the second bending mould, securing the pane against a contact surface of the second bending mould, wherein the press frame is attached to a carrier introduced into the bending zone by a delivery module, and wherein the press frame is moved laterally relative to the first and second bending mould by moving the carrier between the first press frame position and the second press frame position.
CURVED GLASS AND MANUFACTURING METHOD THEREOF
The present disclosure relates to curved cover glass used for a curved display, and a manufacturing method thereof. The present disclosure provides tempered glass comprising: glass including a curved area; and a low-reflection coating layer, coated on a surface of the glass, composed of a mixture of a binder and a hollow material, wherein the glass comprises potassium ions which penetrate up to a predetermined depth therein. According to the present disclosure, a low-reflection coating layer is formed prior to curved surface processing, and thus, the low-reflection coating layer can be uniformly formed even on areas having different curvatures. Thus, the present disclosure can minimize the color difference generated in curved glass due to low-reflection coating layers.
APPARATUS AND METHOD FOR COATING SURFACE OF POROUS SUBSTRATE
The present invention relates to an apparatus and a method for coating a surface of a porous substrate, and according to one aspect of the present invention, there is provided an apparatus for coating a surface of a porous substrate having a first surface and a second surface opposite to the first surface, which comprises: a first supply part for supplying a source gas to the first surface of the porous substrate; a first pumping part for generating a air flow inside the porous substrate in the direction from the first surface of the porous substrate toward the second surface; a second supply part for supplying the source gas to the second surface of the porous substrate; a second pumping part for generating an air flow inside the porous substrate in the direction from the second surface of the porous substrate toward the first surface; and a substrate carrier for transporting the substrate.
Heating objects on a line-production oven
A device for heating objects and a method that has recourse to the device, particularly for heating and/or bending one or more glass panes positioned one on top of the other, covering each other. The device includes a furnace line, plural supports, particularly transport molds that transport and/or bend the objects, the objects being placed on the supports positioned on transport carriages, a drive device that progresses the transport carriages through the furnace line and plural heating elements provided above the objects in the furnace line. In the device the heating elements are positioned on the whole above the entire furnace line and the heating elements can be operated and regulated so as to form heating zones suited to dimensions of the objects.
Method and apparatus for locating a preform on a mold
An apparatus for locating a preform on a mold includes a preform handling tool and a force sensor coupled to the preform handling tool such that the force sensor is capable of sensing forces applied to the preform during handling of the preform by the preform handling tool. The apparatus includes a control device that is arranged and operable to move the preform handling tool relative to the mold. A method of locating the preform on the mold includes picking up the preform using the preform handling tool and placing the preform in a vicinity of the mold. Positions on the mold are mapped with an edge of the preform with the aid of the force sensor. The preform is paced on the mold according to the mapped positions.
Device for bending sheets of glass
A device for bending sheets of glass, includes conveying rollers that convey the sheets one after another in a longitudinal direction, carrying them under an upper bending die and onto a receiving surface formed by the upper level of the rollers under the die. The device includes an intermediate support including a contact path for supporting the sheet of glass to be pressed lying under the die. The contact path has, parallel to the edge of the sheet to be pressed, a curvature that is less accentuated than the curvature that is to be imparted by the upper die. The intermediate support can rise above the receiving surface and support the sheet to be pressed until the sheet breaks contact with the rollers. The intermediate support can be lowered down below the receiving surface. A sheet-pressing system can press the periphery of the sheet against the upper bending die.
Microwave Heating Glass Bending Process
Methods and systems are provided for automated shaping of a glass sheet. The methods comprise preheating the glass, bending the glass through selective, and focused beam heating through the use of an ultra-high frequency, high-power electromagnetic wave, and computer implemented processes utilizing thermal and shape (positional) data obtained in real-time, and cooling the glass sheet to produce a glass sheet suitable for use in air and space vehicles.
