About Foundry Grade Bentonite Lumps

Indias one of the largest bentonitemines owner, processor and exporter. We are exporting super premium qualityBentonite at competitive prices with prompt shipments. We provide all types ofpacking with customized printing options. Sodium bentonite is used extensivelyin iron and steel foundries. For large castings which require dry moulds,Sodium bentonite is put to use. Kutch Bentonite is famous for high qualitysodium Bentonite. It is used popularly as a bonding material in the preparationof moulding sand. Our provided all bentonite is mined in the Kachchh Gujarat,India.

WHY CMS INDUSTRIES?

CMS INDUSTRIES foundry gradebentonite has the ability to develop favourable green and dry compressivestrength and can maintain high thermal stability with the capability todemonstrate excellent ramability. It can sustain mould strength in highpressure moulding. While acting as abinding agent for anhydrous casting sands It has wide moisture tolerance andhigh swelling volume while possessing high wet tensile strength. It also hashigh cohesive strength, thermal stability and low rejects.

Exceptional Binding Properties for Foundry Applications

Our Foundry Grade Bentonite Lumps deliver superior green and dry strength, making them an indispensable ingredient for foundry molding sand. Their high montmorillonite content and significant swelling index enable strong sand cohesion, which is essential for precise casting and mold durability.

Flexible Packaging Options for Diverse Industrial Needs

Available in loose form, 50 kg bags, or 1 MT jumbo bags, our bentonite lumps offer flexibility for transportation and storage. With a shelf life of up to 24 months, users benefit from minimal handling loss and prolonged usability, ensuring efficient supply management for manufacturing requirements.

Quality Assurance and Sourcing from India

Sourced, processed, and exported from India, these bentonite lumps are manufactured under stringent quality control standards. With guaranteed purity and consistent physical properties, customers can rely on stable, high-performance material for their foundry operations.

FAQ's of Foundry Grade Bentonite Lumps:

Q: How are Foundry Grade Bentonite Lumps utilized in the molding sand binder process?

A: Foundry Grade Bentonite Lumps are mixed with sand and water to create a molding sand binder. The clay's high swelling index and water absorption enable it to encapsulate sand grains, providing excellent green and dry strength needed for casting molds.

Q: What benefits does a high montmorillonite content provide for foundry applications?

A: A high montmorillonite content (minimum 80%) enhances the lumps' ability to bind sand efficiently, resulting in robust molds that retain their shape during casting and reduce defects in finished metal products.

Q: When should the bentonite lumps be replaced or replenished in a foundry process?

A: Bentonite lumps should typically be replenished after every molding cycle or when the binding properties decrease, indicated by reduced mold strength or increased casting defects. Their shelf life of 24 months allows for long-term storage without significant degradation.

Q: Where are these bentonite lumps sourced and manufactured?

A: These Foundry Grade Bentonite Lumps are sourced, manufactured, and exported from India, adhering to international standards for purity, consistency, and performance.

Q: What is the recommended method for storing bentonite lumps to maintain quality?

A: To maintain quality, store bentonite lumps in dry, covered areas, preferably in sealed bags or containers. This helps prevent moisture absorption beyond the specified 8-12% and ensures the lumps retain their binding capabilities throughout the shelf life.

Q: How does the high water absorption rate improve molding sand performance?

A: The high water absorption rate ( 300%) aids in creating a homogeneous sand mixture, improving mold plasticity, reducing cracks, and ensuring accurate reproduction of casting patterns.
