Reliable Casting Starch for Industrial Applications

Foundry Starch (α-Starch) is a key functional clay sand casting material to improve the level of clay sand casting process. It is specially developed to solve industry pain points such as thermal stress, sand drop and cracks, and is a high-performance, environment-friendly and low-cost high-quality cast iron auxiliary material. Through deep α-modification treatment, this product has excellent water solubility, expansibility and high-temperature loss property. It is evenly dispersed between sand particles during sand mixing, forming a flexible buffer structure; heated and lost during pouring, retaining tiny pores, absorbing sand mold thermal expansion stress, protecting castings from extrusion deformation. As a core clay sand casting material, this product can effectively enhance the moisture retention capacity of sand molds, form a stable moisture condensation layer, avoid problems such as cavity surface drying, sand drop and peeling, and improve the overall quality and molding accurac…
