Ductile-iron front-cover component for injection-molding machinery.
Hengong lists a front cover for a mold-moving oil cylinder among its injection-molding-machine parts. The page identifies ductile iron and labels the product as rough-machined, while describing CNC and machining-center production. Buyers should therefore agree the exact delivery stage and remaining machining allowances instead of assuming a fully finished, assembly-ready cover.
