Heat-transfer process during hot-pressing of flakeboard
Frontiers of Forestry in China, 2006Hot-pressing is the main process in flakeboard manufacture. Studies in this field also emphasize the effect on the heat-transfer process of the following factors: hot-pressing temperature, original moisture content (MC), target thickness and target density.

Processing Zirconia by Sintering/Hot Isostatic Pressing
Advanced Ceramic Materials, 1988Sintering followed by hot isostatic pressing is a potential method for improving the mechanical properties of ceramic materials. Encouraging data have been presented and published but these data do not clearly show the origin of the benefits. Here, the effects of green density, time, temperature, and pressure on sintered density, grain size, and pore ...

Hot isostatic pressing process simulation: application to metal powders
Canadian Journal of Physics, 2012Deformation and transport mechanisms of matter, which intervene in the powder densification process by hot isostatic pressing (HIP), are very complicated to put into equation form. Their contribution to densification depends on powder characteristics, their configuration in aggregates, and the used HIP cycle parameters (temperature, pressure, and time)

‘Reactive Hot Pressing’ : a New Ceramic Process
Nature, 1965REACTIVE hot pressing is a new process by which powdered materials can be densified and materials of considerable strength can be produced. The term ‘reactive hot pressing’ is new and has been coined to distinguish this process from other known ceramic processes, such as sintering, hot pressing or pressure fabrication.

Hot-pressed porcelain process for porcelain-fused-to-metal restorations
The Journal of Prosthetic Dentistry, 1975A technique has been described that simplifies the production of full-coverage, porcelain-fused-to-metal restorations. The process utilizes a furnace-flask system in which the restoration is invested in a high-temperature refractory material and processed at an elevated temperature (1,850 degrees F.) under pressure.

Hot press molding process for pyramid-type glass optical multiplexer
Optical Engineering, 2014By developing a pyramid-shaped reflector, we were able to remove the optical filter that causes the decline in light efficiency in existing systems. A pyramid-type glass optical multiplexer (MUX) can be designed for beam coupling efficiency >60% in a combined module.
