High speed sand molding releases heat quickly by producing new molds on a rapid basis. With metallic molds used in high pressure diecasting and permanent mold, a single mold must do all the heat extraction while periodically having hot metal poured or injected into it. ... Cooling Lines Permanent molds can be air- or water-cooled. Air-cooling ...

Dense Phase works by medium to high-pressure air (10 to 60 psi) with velocities in the pipe of 2,800 to 5,000 feet per minute. Dense Phase systems fluidize the sand for transport and use booster (injection of additional air along the pipeline) to keep the sand in the pipeline fluidized.
The Green Sand Molding Process. The term Green Sand denotes the presence of moisture in molding sand and indicates that the mold is not baked or dried. Raw sand is mined and then processed to give it a consistent distribution of grain sizing. When processed for molding, organic clays are added to bond the grains together.
Pressure casting, also known in manufacturing industry as low pressure casting or pressure pouring, is another variation of permanent mold casting. Instead of pouring the molten metal into the casting and allowing gravity to be the force that distributes the liquid material through the mold, pressure casting uses air pressure to force the metal ...
