The match plate pattern is typically used in high production industry runs for sand casting manufacture. A match plate pattern is a two piece pattern representing the casting, divided at the parting line, similar to the split pattern. In the match plate pattern, however, each of the parts are mounted on a plate.

The economic implications of sand problems are critical enough to require continuous improvement in sand-control techniques and sand production prediction methods. When developing a sandstone oil or gas reservoir, a prediction of sand production is required to evaluate the necessity of sand control [2] .

 · As most producing fields rely on an exclusionary approach to sand management, retrofit of sand separation equipment into existing facilities is a common method of treating unplanned sand production. The retrofit design is an economic decision that balances sand production issues with space, weight, and process constraints.

Sand production erodes hardware, blocks tubulars, creates downhole cavities, and must be separated and disposed of on surface. Com-pletion methods that allow sand-prone reservoirs to be exploited often severely reduce production efficiency. The challenge is to complete wells to keep formation sand in place without unduly restricting productivity.

Oil production may be accompanied by Sand Production (SP) in the weak sandstone reservoirs. Fluid flow is an important factor in transporting the separated grains and completing the SP mechanism. In this paper, the effect of fluid parameters, fluid flow, and fluid pressure on the SP is investigated by applying the Discrete Element Method (DEM).

 · • The "dry sand" consists of sand and synthetic binders cured thermally or chemically. The sand cores used for forming the inside shape of hollow parts of the casting are made using dry sand components. This versatile technique is generally used for high-volume production.

Sand casting is a process that utilizes non-reusable sand molds to form metal castings.It is a common production method for metal components of all sizes, from a few ounces to several tons. Sand casting isn't only versatile in the size of its products – it can also create exceptionally complex or detailed castings, and can be used to cast nearly any metal alloy.

Sand casting is a process that uses a mold made from either metal, wood, or wax to create a negative impression in a special sand that will be the mold for the molten metal. This mold is then filled with a molten metal that is left to cool and solidify. Once the metal has solidified the mold can be hit with a hammer, pipe, or any hard object to ...
