recycled foundry sand - uses & applications  -  die casting industry
Recycled foundry sand can be defined as a product of the black and non-ferrous metal casting industry in which sand has been used as a molding material for centuries due to its excellent thermal conductivity
In the current foundry, sand is usually recycled and reused through different production cycles.
According to industry experts, about 100 million tons of sand is used for production every year.
Of these 100 million tons of sand, 6 to 10 million tons are discarded each year, and sugar cane is recycled into other products and industries.
The sand used by the foundry is of superior quality because the company adopts strict physical and chemical tests to ensure the production of defect-free castings.
The foundry has invested heavily in the quality control of its sand system and has conducted rigorous testing to ensure consistency.
Although there are several methods of casting, including-
Sand casting is the most popular casting technology at present, including die casting, investment casting and metal casting.
There are two different ways of using sand in the metal casting industry
Because sand grains are not naturally adhering to each other, the adhesive is used to make the sand stick together and maintain its shape during the introduction of molten metal into the mold and cooling the casting.
Sand type metal casting industry for recycled casting generally uses two adhesives
Both types of sand are suitable for recycling and utilization, but they have different physical and environmental properties.
The use of recycled foundry sand from black and aluminum foundry accounts for more than 90% of the available sand, and is usually best suited for recycling.
Compared to other non-ferrous metal foundries, black and aluminum foundries are generally large in size and they have a more uniform flow of sand due to the nature of their production.
This type of sand has a history of use in different types of building applications.
Some innovative foundries are looking for ways to recycle old sand.
Other types of nonferrous [
Http: like other materials, transportation costs are often the highest cost factor in casting sand recycling.
Taking into account the cost factors, the best option for casting sand recycling is usually matched with businesses and construction projects in nearby areas.
Here are some markets that have the potential to absorb recycled foundry sand from different foundry types --
In some other cases, sand for casting can replace a portion of fine aggregates in several other types of applications, most of which exist in different markets and countries on a commercial scale.
These applications include
