Permeability is a property of foundry sand with respect to how well the sand can vent, i.e. how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases. The permeability is commonly tested to see if it is correct for the casting conditions. [1]
The first patent for an evaporative-pattern casting process was filed in April 1956, by Harold F. Shroyer. He patented the use of foam patterns embedded in traditional green sand for metal casting. In his patent, a pattern was machined from a block of expanded polystyrene (EPS), and supported by bonded sand during pouring. This process is now ...
In casting, a pattern is a replica of the object to be cast, used to form the sand mould cavity into which molten metal is poured during the casting process. Once the pattern has been used to form the sand mould cavity, the pattern is then removed, molten metal is then poured into the sand mould cavity to produce the casting. The pattern is non ...
Aesop's Fables, or the Aesopica, is a collection of fables credited to Aesop, a slave and storyteller who lived in ancient Greece between 620 and 564 BCE. Of varied and unclear origins, the stories associated with his name have descended to modern times through a number of sources and continue to be reinterpreted in different verbal registers ...
Rosemary Wells, reviewing Aesop's Fables wrote "Pinkney's Aesop is a visual treat. These are beautiful illustrations, combining pencil, colored pencil and watercolor with a light-as-air touch. .. The book is handsomely designed, in a large format, and fine paper sets off the illustrations to their best advantage." [1]
The pattern is a model of the desired casting. Talcum powder is often dusted over the pattern to aid in the removal of the pattern. Sand is sifted over the pattern until the model is covered by a few inches of sand. More sand is then dumped into the drag, and rammed with a wooden wedge, or mechanically vibrated to pack the sand down.
