An optical lens molding device includes a raw material supplying unit for providing a solid-state optical material, a feeding unit for transporting the solid-state optical material along a feeding direction, a heating unit including a heating body and a heating conduit in spatial communication with the supplying unit for entering of the solid-state optical material, and a molding unit. The heating conduit has a downstream part extending in the heating body to heat and melt the solid-state optical material in the heating conduit into a fluid-state optical material. The molding unit defines a cavity and a sprue in communication between the cavity and the downstream part to permit the molten fluid-state optical material to be pressed by the solid-state optical material and to flow in and fill the cavity through the sprue.

An injection molding method includes the steps of:(A) preparing a molding unit and an injection unit, the molding unit including a first mold having a protruding portion, and a second mold having a movable post cooperating with an inner peripheral surface thereof to define a cavity; (B) moving the molds toward each other until the protruding portion cooperates with the second mold to define a forming space; (C) activating the injection unit for injecting the molten optical material into the forming space; (D) cooling the molding unit; and (E) moving the molds away from each other and subsequently activating the movable post to push a solidified optical material out of the forming space.

In the conventional direct press method, it was difficult to control the weight of molten glass gob when manufacturing a small precision glass component and thus the weight of the glass gob varies widely. Accordingly, the problem is that the precise molding cannot be expected stably. As a solution, the present invention provides a mold for molding a glass-made optical component and a manufacturing method using the mold, the mold comprising: a female mold which has a lower mold of a molding mold for molding the glass-made optical component on an outer peripheral portion of a concave surface of the female mold; a male mold which has a convex surface combined with the concave surface of the female mold; and a ring mold which is arranged on an outer peripheral portion of the male mold, the ring mold having an upper mold of the molding mold for molding the glass-made optical component, wherein molten glass gob introduced into the concave surface of the female mold is configured to be pressed from above by the male mold having the convex surface so that the molten glass gob is injected into a space formed between the lower mold and the upper mold of the molding mold.

The present disclosure relates to a glass tile and a method of making a glass tile using a glass pressing technique. The glass tile may include a tile body of substantially homogenous glass material, an annular rim extending in a marginal portion of the tile body, and a cavity provided in a central portion of the tile body such that the glass tile forms a multi-sided compartment. A predefined texture may be disposed on at least part of the glass tile to provide a desired visual effect and/or a desired optical effect. The glass tile may be incorporated into a decorative assembly or structure such as flooring, roofing, doors and windows, landscaping and facades, and lighting.

A blank mould base pressing system (9) for forming a burr-free mouth entry for a glass container to be produced, which blank mould base pressing system comprises a piston (9.1) which is operated by charging with gas pressure, preferably with compressed air (18), and a pressing element (10) having a pressing-element profile (10.3), wherein the piston (9.1), when it is charged with gas pressure on one side, brings the blank mould base pressing system (9) into a pressing position in relation to a glass gob (1) which is in a blank mould (2) and is to be moulded and, on contact of the pressing-element profile (10.3) with the glass gob (1), forms a base for the glass container to be produced, wherein the blank mould base pressing system (9) has a means for controlling or regulating the stroke of the piston (9.1), wherein said stroke of the piston (9.1) serves to compensate for mass fluctuations of the glass gob (1), and a method for producing a parison (1.1) by means of the aforementioned blank mould base pressing system (9), wherein the blank mould base pressing system (9) has an internal cooling device for cooling by means of a cooling medium, and a method for producing a parison (1.1) by means of the blank mould base pressing system (9) according to the invention.

An injection molding system and method of operating the system are disclosed. The system may include a hopper, a barrel configured to receive injection material from the hopper, a screw disposed within the barrel, and a mold defining a mold cavity configured to receive the injection material from the barrel. A pressure-balancing conduit may connect the mold cavity and a rear end of the barrel and be configured to allow air to flow from the mold cavity to the rear end of the barrel. A mold valve may be disposed between the pressure-balancing conduit and the mold cavity and a barrel valve may be disposed between the pressure-balancing conduit and the rear end of the barrel. The method may include opening the mold valve and injecting a material into the mold cavity from the barrel.
