Casting Starch for Metal Casting Applications

Facing the precision casting demand of high-end cast iron parts, Foundry Starch (α-Starch) creates a high-performance clay sand casting material with modified polymer structure, providing multiple functions such as thermal stress buffer, surface enhancement and sand drop prevention for the clay sand system, making it a professional and reliable cast iron auxiliary material. This product adopts advanced pre-gelatinization process to fully activate starch molecules, which quickly absorb water and expand during sand mixing, evenly distributed in sand gaps, forming an elastic support structure; no residue after high-temperature loss during pouring, forming uniform micropores, effectively absorbing sand mold thermal expansion, avoiding casting defects such as hot cracking, deformation and sand inclusion. As a core clay sand casting material, this product can strengthen the surface density of sand molds, enhance the adhesion between sand particles, prevent problems such as cavity sand drop a…
