Sodium Silicate for Making Foundry Cores

Sand is mixed with a binder to form a solid "sand core". A core must porous enough to allow gas to escape from the casting, while still blocking the molten metal. It should also be easily removed from the finished casting. Sodium Silicate is used as the binder that "glues" the sand together in cores. For example, imagine making a cannon.

Making "Core" Sand and Curing the Molds

2013-9-15 · The same thing applies to making core sand for your molds. Everyone has their own "PET" formula for making their sand. AND many won't give out their 'secret' formula. Many of my designs are not new just modified the basic concepts to my own ideas and I think improvements.

Sand cores are produced by blowing a sand-air mixture into a mold. The foundry engineer's objective is to achieve a homogeneous sand distribution with a sufficient packing of the sand in order to avoid air enclosures in the sand and achieve a good stability of the core....
