Modernisation and Mechanisation of Foundries Casting

Mechanisation of foundries is necessary where permitted (depending on the quantity and type of production) in order to improve the working conditions in foundry increased production and quality of casting lowering down the cost elimination of laborious manual operations like preparation of sand moulds and various other material handling operations.

Aluminum Forming Effluent Guidelines Effluent Guidelines

If the aluminum is a remelted primary aluminum product and is cast at a facility for subsequent forming of aluminum then the casting of remelted aluminum is subject to the Aluminum Forming Category limitations. Other aluminum casting operations are subject to the Metal Molding and Casting (Foundries) Category (40 CFR Part 464). EPA promulgated the Metal Molding and Casting (MMC) Effluent Guidelines and Standards (40 CFR Part 464) in 1985. MMC facilities discharge process wastewater directly to surface waters or indirectly to surface waters through publicly owned treatment works (POTW).

Metal Products and Machinery Effluent Guidelines

EPA promulgated the Metal Products and Machinery (MP M) Effluent Guidelines and Standards in 2003.

Metal Finishing Effluent Guidelines Effluent Guidelines

Metal Finishing Effluent Guidelines EPA promulgated the Metal Finishing Effluent Guidelines (40 CFR Part 433) in 1983 with technical amendments in 1984 and 1986. The regulations cover wastewater discharges from a wide variety of industries performing various metal finishing operations. Casting Need to Know Guide. In metalworking casting is the process of setting molten metallic material in a pre-designed mold. Once the molten metal cools it becomes a solid metal object in the desired shape. Casting can be achieved with a wide variety of metals and various materials can be used to form the molds and other equipment.

Metal Casting--Industry of the Future

Cast metal products are found in 90 percent of manufactured goods and equipment. From critical components for aircraft and automobiles to home appliances and surgical equipment cast metal products are integral to our economy and our way of life.
