Resin Sand Casting
YBMETAL offers Resin Sand Casting (furan resin casting) for producing large, high-strength gray iron, ductile iron, and cast steel parts. This chemically bonded sand process ensures superior mold strength, surface finish, and dimensional accuracy—ideal for structural, pressure-bearing, and CNC-machined components. As a full-service China casting supplier with in-house CNC machining, we deliver OEM-grade resin sand castings from 5 kg to 8,000 kg—fully machined, inspected, and export-ready with PPAP and CMM reports.
What Is Resin Sand Casting?
Also called furan resin sand casting, this process uses chemically bonded sand molds to produce large, complex iron and steel components. Compared with green sand or shell molding, resin sand offers superior mold strength, surface finish, and dimensional stability, making it ideal for heavy-duty or structurally demanding parts.
Why Choose Resin Sand Casting?
- ✅ Suitable for large and heavy parts: High mold rigidity allows casting of iron and steel parts up to 8 tons — perfect for pump housings, machine beds, and gearboxes.
- ✅ Improved surface quality & tighter tolerances: Compared to green sand, resin molds reduce casting defects and machining allowance, saving post-processing time.
- ✅ Excellent for complex internal cavities: Custom resin cores enable high-precision oil galleries, duct channels, and thick-walled structures.
- ✅ Reliable cooling and heat treatment: Even solidification helps reduce stress and ensures dimensional consistency after post-cast heat treatment.
- ✅ Material flexibility: Supports gray iron (HT200–HT300), ductile iron (QT450–QT700, EN-GJS-500-7), and cast steel (ZG230–450).
