Advanced Foundry Starch Material Solutions

In modern clay sand casting process, Foundry Starch (α-Starch), as a special high-performance clay sand casting material, has become an important cast iron auxiliary material to ensure the stable quality of cast iron parts by virtue of its unique thermal stress relief mechanism. When the temperature of molten metal exceeds 1300℃, the sand mold will expand rapidly by heat. α-Starch has extremely strong expansion capacity through pre-gelatinization modification, occupying uniform space during sand mixing, forming buffer pores after high-temperature loss, which can efficiently absorb thermal stress and fundamentally solve problems such as hot cracking, sand swelling and deformation of castings. As a core clay sand casting material, this product can significantly enhance the surface adhesion of sand molds, prevent defects such as dry sand drop and sand wash in the cavity, and improve the overall integrity of sand molds and pouring stability. This product has high compatibility with foundry…
