Scrap metal can be made into sustainable as well as purified commodities. Recycled aluminum is one of the most popular raw materials involved in the making of mass components of automobiles.
Scrap metals such as steel, cast iron, and copper can be recycled more than once just like aluminum scrap. Rather than dumping them into landfills, professional foundries source scrap metal and recast them into commodities through die cast mold making or pressure die casting processes to reduce the manufacturing costs.
Apparently, scrap metal is categorized into three and each metal scrap category has its own life span. Home scrap refers to the trimmings, pigged metal, as well as mill rejects or rejects generated in a foundry. Prompt scrap is left in OEM fabricators’ factory and just like home scrap, prompt scrap is also returned to the foundry for purification. The chemical properties of both home scrap and prompt scrap are known to the die casters in Mexico.
Obsolete scrap metal is sourced from automobiles, appliances, ships, and factory landfills. However, the chemical properties of obsolete scrap remain unknown due to wear and wear, are they are usually sorted out in a scrap yard and recycled for reuse.
Foundries refine raw prompt scrap and obsolete scrap into commodity grade raw materials. They also source scrap metal through auto salvage facilities, scrap yards, and dealers, and purify the same with state-of-the-art facilities.
Scrap yards shred the scrap metal with metal shredders into small pieces so that it can be sorted into ferrous, non-ferrous, as well as non-metallic materials. However, oversized scrap or scraps that are too large to shred are resized and sorted manually.
Ferrous alloys contain iron such as steel, malleable iron, or gray iron, are identified by magnetism, and filtered using an electromagnet. Any scrap metal not containing iron is referred to as non-ferrous metal and that includes aluminum and copper-based alloys. Non-ferrous metals are non-magnetic, corrosion resistant, and are heavier than non-metallic raw materials.
Scrap yards use metal scrap recycling systems conveyor belts, automotive conveyors, and radial stackers, whereas automatic shredders separate the different types of metal and scrap. Regardless, purification and refinement of scrap metal occurs after separating the ferrous and non-ferrous metal. To make the metal scrap into a commodity, scrap metal is purified and refined by die casters. The foundries that do pressure die casting or die cast mold making convert both new and old aluminum scrap into a foundry ingot.
