Amongst many molding system (Die Casting, Investment Casting, Lost Foam Casting, Vacuum Casting …) traditional sand casting is probably the most common molding system widely used. Sand Casting basically requires: agglomerate (bentonite or chemicals binders), water, additives and sands.
With approximately 100 million tons, quartz/silica sand is the main material used in foundry. However, technical needs within the foundry production are increasingly specific and tailor-made and new special sands are constantly introduced to the market. All players of the foundry market know zircon and chromite and their yoyo price fluctuations which depend on various market trends.
Imerys for Foundry Applications offers a full range of refractory sands which are all based on aluminosilicate and are specially designed (AFS, Particles Size Distribution) for mold and cores production. Our cost effective special sand portfolio covers all types of technical, environmental and health requirements of the foundry industry.
