What is the difference between die casting and pressure die casting?
In sand mold casting the molten metal is poured in to the mold cavity , while in pressure die casting the molten metal is forced under high pressure in to the cavity. The sand casting process is used for small batch production where pressure die casting is used for mass production.
When do you use solid pattern for casting?

ans is none because top gate are used in very large casting due to erosion occur in this casting
Why do you think the sand is used?
Green sand is a mixture of sand with bentonite clay, pulverized coal, and water used in metal casting. It is not necessarily green in color, but is called green because it is used while wet, like the "green wood" sometimes used by wood turners.

Where are the freeze plugs on a 97 Grand Marquis?
If it has them they are located on the side of the block. They are actually casting plugs used to remove sand during casting, and have nothing to do with protection from freezing.
What is the process sand casting used for?

In what industries is aluminum casting generally used?
Castings are generally sound, provided that the alloys used exhibit good fluidity. Aluminum is one of the few metals that can be cast by all of the processes used in casting metals. These processes, in decreasing order of amount of aluminum casting, are: die casting, permanent mold casting, sand casting (green sand and dry sand), plaster casting, investment casting, and continuous casting. Other processes such as lost foam, squeeze casting, and hot isostatic pressing are also mentioned.
What oil do you mix with sand to make oil bond sand for casting?
Typically, resin binders like furan resin or phenolic resin are used to bond sand for casting metal. These resins are mixed with sand to create a strong and heat-resistant mold for the casting process. Oil is not typically used for this purpose.
What is the difference between die casting and pressure die casting?

How can sand mold be used in the process of creating metal castings?
Sand mold is commonly used in metal casting as it can withstand high temperatures and is easily moldable. The process involves creating a cavity in the sand mold that matches the desired shape of the metal casting. Molten metal is then poured into the cavity and allowed to cool and solidify, resulting in a metal casting that replicates the mold's shape. Sand mold is cost-effective and versatile, making it a popular choice in the metal casting industry.
What is permeability in sand casting?
This allows the gases and steam to escape from the mold during casting. The grain size, shape and distribution of the foundry sand, the type and quantity of bonding materials, the density to which the sand is rammed, and the percentage of moisture used for tempering the sand are important factors in regulating the degree of permeability.
