Resin Sand Casting Production Process in Dandong Pengxin
Mar 08, 2025
Resin sand casting is an advanced metal casting process that involves mixing high-quality raw sand with specialized resin binders (such as furan, phenolic, or alkaline phenolic resin) to form a strong, moldable sand mixture. This resin sand is then packed into mold cavities and cured—either through heat or chemical hardening—to create precise, durable molds. Once the mold is set, molten metal is poured into the cavity, producing high-integrity castings with excellent dimensional accuracy.
