Soluble Glass Process

Soluble Glass Process
Soluble Sodium Silicates(waterglass) are liquids containing dissolved glass which have some water like properties.They are widely used in industry as sealants,binders,deflocculants,emulsifiers and buffers.
Soluble sodium silicate process has a minimal environmental impact because the process has no harmful byproducts and makes naturally occuring endproducts.
The process is generally used for small castings, but has produced complete aircraft door frames, steel castings of up to 300 kg and aluminium castings of up to 30 kg. It is generally more expensive per unit than die casting or sand casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.
