Using Kiln Dried Silica Sand
For many years there has been a requirement for high quality silica sand in the Foundry industry. Foundries use the clean, well graded sand to produce moulds for the production of metal castings which are the basis of engineering and manufacturing industries across the UK.
High purity silica sand is washed and graded to remove any impurities and then kiln dried before it is delivered to the foundry. Because this type of sand has a higher melting point than iron, copper, aluminium and other alloys it can be mixed with a binder (sodium silicate) before passing Co2 gas through it to harden it to produce a mould that can hold the molten metal when producing a casting. The sand is classified into different sizes which affects the amount of binder required and the final surface finish of the casting.
The sand mould is later broken away from the casting and can be recycled within the larger foundry or used elsewhere in the production of asphalt or concrete products.
Follow appropriate health and safety procedures whilst mixing.
