Resin Sand Process
Coated Sand Process

Resin Sand Process

For Large-Scale & Heavy-Duty Castings

Our Resin Sand process is ideal for producing large, heavy, and structurally demanding castings. Using robust metal or wood patterns, High-strength sand shell, with a smaller draft angle,24 to 72 hours of insulation time.this process provides a cost-effective solution for low-to-medium volume production runs where structural integrity is paramount.

Key Specifications Table

Casting Weight: 50 kg – 10,000 kg

Best For: Low-to-medium volume (tens to hundreds annually)

Materials: Gray Iron (HT200,HT250,HT300,).Ductile Iron (QT400-QT450-QT500-QT600)

Applications: Machine Tool Bases, Large Housings, Construction Machinery Frames

Coated Sand Process

For High-Precision & High-Volume Components

When precision and surface finish are critical, our Coated Sand process delivers exceptional results. Using high-precision, long-life iron molds (100,000+ uses), By using the core shooter, we can produce more precise sand molds with a smaller draft angle.we achieve accuracy errors within 0.5mm, the surface roughness reaches Ra25.making it perfect for complex parts in high-volume production.

Key Specifications Table

Casting Weight: 5 kg – 1,000 kg

Best For: Hundreds to tens of thousands

Materials: Gray Iron (HT200,HT250,HT300,).Ductile Iron (QT400-QT450-QT500-QT600)

Applications: Valve, Cylinder block, Transmission parts
