Disclosed herein are methods for producing glass articles by hot-melt processing techniques. The methods involve the use of arsenic-free chalcogenide glasses. Despite the absence of arsenic, the chalcogenide glasses have low characteristic temperatures and are stable against crystallization. The low characteristic temperatures render the glasses capable of being hot-melt processed using conventional equipment. The glasses disclosed herein are suitable for the fabrication of optical devices, including but not limited to IR-transmitting optical devices.

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.

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.

A method of manufacturing a heat exchanger core from glass ceramic matrix composite includes placing one or more reinforcing fibers around one or more mandrels into a mold cavity. A glass matrix material infiltrates the one or more reinforcing fibers to produce an infiltrated core and the one or more mandrels is removed to create one or more passages passing through the infiltrated core.

A glass forming machine, a method for lubricating a baffle and a swabbing device for a glass forming machine is disclosed. The glass forming machine comprises a blank station with a blank mould for forming a parison from a gob of molten glass inside the blank mould. The glass forming machine further comprises a baffle for closing the blank mould. The glass forming machine further comprises a swabbing device which is configured to spray lubricant onto the baffle for lubricating the baffle. This enables a particularly high quality of the formed parisons and the corresponding glass containers.

A method of forming a chalcogenide glass element, the method includes depositing molten chalcogenide glass from an injection tip of a nozzle and into a cavity of a mold at a flow rate, the nozzle being inserted into the cavity, and during the depositing, moving at least one of the nozzle and the cavity relative to each other to substantially fill the cavity with the molten chalcogenide glass, and changing the speed of the at least one of the nozzle and the cavity based upon alignment of the injection tip with a cross-sectional radius of the cavity.

Provided with a glass flow passage mold having a lower mold provided on a female mold and an upper mold provided on a ring mold to connect the female mold, the ring mold and a molding mold having a lower molding mold and an upper molding mold into which molten glass gob is injected. The lower mold of the glass flow passage mold can be integrated with the female mold and detached from the female mold. The upper mold of the glass flow passage mold can be integrated with the ring mold and detached from the ring mold. In addition, the glass flow passage mold can be integrated with the molding mold. The above described features significantly improve the manufacturing yield and the productivity.
