Foundry Starch Material Selection Guide

Foundry Starch (α-Starch), as a green high-performance clay sand casting material, with natural raw materials, modified structure and multi-functional characteristics, has become an indispensable environment-friendly cast iron auxiliary material in modern cast iron production. Through strict α-modification process, this product has excellent thermal expansion absorption capacity, surface enhancement capacity and sand drop prevention capacity, playing a stable, efficient and lasting role in the clay sand system, comprehensively improving molding sand high-temperature performance and process adaptability. As a core clay sand casting material, this product can be lost to form a microporous structure during high-temperature pouring, absorbing sand mold thermal stress, avoiding casting defects such as cracks, deformation and sand inclusion; at the same time, strengthen the moisture condensation layer, keep the cavity moist and stable, prevent sand drop and peeling during molding, and improv…
