Casting Technology, include casting methods, casting material and casting standards.
Casting is a manufactureing process in which molten metal is poured or injected and allowed to solidify in a suitable shaped mold cavity. During or after cooling, the cast part is removed from the mold and then processed for delivery. Casting processes and cast-material technologies vary from simple to highly complex. Material and process selection […]
This specification covers carbon steel castings for valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding. Covered here are three grades of carbon steel (Grades WCA, WCB, and WCC), the selection of which shall depend on the design and […]

Product Analysis is the process of identifying, looking at or disassembling a product and identifying its main features. The aim is to understand more about a product and improve it in the future. Many factors influence the development of a product, some are listed below.
Die-casting is similar to permanent mold casting except that the metal is injected into the mold under high pressure of 10-210Mpa (1,450-30,500) psi . This results in a more uniform part, generally good surface finish and good dimensional accuracy, as good as 0.2 % of casting dimension. For many parts, post-machining can be totally eliminated, […]
How to control the lost wax casting : Casting size and shape determines the tolerance required to allow for process variables. Many process factors affect investment casting tolerances, such as: 1.Wax temperature
Sand casting is used to make large parts (typically Iron, but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). The processes of sand casting are discussed in this section, include patterns, sprues and runners, design considerations, and casting allowance.
