Foundry bentonite – an essential material for high-quality castings

Casting bentonite is a high-quality casting auxiliary material with good plasticity and flowability, which can improve the surface quality and internal structure stability of castings. This product is suitable for various casting processes, especially sand casting and precision casting.

Cast bentonite is composed of natural bentonite and special polymers, and has the following advantages:
1. High temperature stability: Cast bentonite can maintain stable physical and chemical properties in high-temperature environments, and is not easy to decompose and melt.
2. Good flowability: Cast bentonite has excellent flowability and can smoothly fill small voids and complex structures in sand casting.
3. Strong Plasticization: Casting bentonite can effectively plasticize castings, avoiding cracks and defects in the production process.
4. Environmental protection and health: Cast bentonite is made of natural mineral materials, free from harmful chemical components, and meets environmental and health requirements.
Our casting bentonite has passed the ISO9001 quality management system certification and obtained
