Our range includes:

· Green sand system: 

Bentonite, coal dust, starch, α-starch, pre-mixed additives for high-pressure molding lines and hand molding.

· Resin sand system: 

Furan resin, phenolic resin, PEP SET resin, hardeners (PTSA, sulfuric acid ester) for medium-large resin sand castings.

· Shell mold: 

Phenolic resin coated sand, shell release agents for precision shell casting.

· Lost foam: 

RPS beads, STMMA copolymer beads, lost foam coatings (water-based/alcohol-based).

· V-process: 

RVA film, vacuum suction film, V-process specific coatings.

· 3D printing: 

3D printing-specific sand (cerabeads, ceramsite sand, etc.), 3D printing-specific resin (furan/alkaline phenolic, etc.), 3D printing-specific coating

Special / Synthetic Sands:

· Cerabeads: 

Spherical, low thermal expansion, high refractoriness – ideal for precision steel castings, large steel castings and resin sand process.

· Ceramsite: 

Lightweight, good insulation – filling sand for lost foam and V-process.

· Chromite sand: 

Strong chilling effect – used for thick-wall steel castings and hot spots.

· Zircon sand: 

High refractoriness, low expansion – face sand for investment casting.

· Olivine sand: 

Alkaline – suitable for high-manganese steel castings.

· Corundum sand: 

Ultra-high refractoriness – for superalloy and stainless steel castings.

We provide grading optimization solutions to reduce binder consumption and casting defects. All products with material certificates, particle size analysis, and environmental compliance (REACH, RoHS).
