Green Sand Casting
YBMETAL delivers high-volume Green Sand Casting services for OEMs seeking efficient, cost-effective production of ductile iron and gray iron parts. As a full-process casting supplier based in China with in-house CNC machining, we offer fast turnaround for green sand castings from 2 kg to 500 kg, fully machined and backed by international quality standards.
What Is Green Sand Casting?
Green Sand Casting uses a mixture of natural sand, bentonite clay, water, and additives to form reusable molds for molten metal. Known for its cost-efficiency and adaptability, it is the most widely used process for ductile iron and gray iron casting production. Compared with resin sand or shell molding, green sand excels in low tooling cost and rapid cycle times, making it ideal for medium- to high-volume production with standardized part geometries.
Why Choose Green Sand Casting?
YBMETAL partners with ISO-certified foundries equipped with full shell molding lines, including:
✅ Best for high-volume, low-cost iron castings
Green sand molds are quick to prepare and re-use, making this process ideal for mass production of iron components with stable dimensional tolerances.
✅ Excellent material compatibility
Supports both gray iron (HT200–HT300) and ductile iron (QT450–QT700, EN-GJS-500-7), suitable for industrial, agricultural, and commercial parts.
✅ Flexible mold sizes and core configurations
Capable of casting complex cavities and structural parts from 2 kg to 500 kg, using manual or automated molding lines.
✅ Efficient solidification and cooling
The permeability of green sand allows controlled heat dissipation, reducing internal stress and improving the base mechanical properties.
✅ Eco-friendly and cost-efficient
Green sand can be reclaimed and recycled, minimizing waste and reducing production cost compared to resin or shell molding processes.
