What are the key properties of sodium bentonite?

Sodium bentonite features high swelling capacity, high dry compressive strength, high hot wet tensile strength, and good reusability.

How does bentonite improve casting quality?

It binds sand grains to form strong molds, controls moisture/permeability to reduce gas defects, and ensures smooth casting surface finish.

What is the main application of this product?

It is primarily used in the metal casting industry for preparing 'green sand' molds in ferrous and non-ferrous metal casting processes.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical bentonite supplier with crushing, drying, grinding, and activation capabilities, more than 10 production lines, and stated annual output of 1,200,000 tons. It offers OEM, ODM, and limited customization services, but does not provide 3D software design, SDKs, or evidence of new products in the past year. Quality assurance is reported, while supplier approval, corrective-action, and complaint-handling procedures lack documented records. Overseas service coverage is limited: no overseas showroom, agents, branches, or offline trade-show participation are reported. RoHS is the only stated certification. Financial information is incomplete and largely represented by placeholder values, so financial credibility cannot be reliably assessed. No specific customer cases are provided.

Supplier typeThe supplier explicitly identifies as a professional technical supplier and describes bentonite production using crushing, drying, grinding, and activation technologies. Its factory information indicates more than 10 production lines and production focused on bentonite.

CertificationsRoHS is explicitly listed as the supplier’s sustainable-development and product-certification capability. No other certifications are provided in the supplied information.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, bentonite output of 1,200,000 tons, and infrastructure including production facilities and a quality-assurance laboratory. These data explicitly support substantial production capacity, although the stated capacity figures are not fully consistent across the slices.

Customization capabilityThe supplier provides minor customization and customization from customer designs, and explicitly offers ODM and OEM services for popular brands. This supports a clear ability to adapt or manufacture according to customer requirements, though 3D software design and SDK support are unavailable.
