The different granulometries and resistance levels of the foundry sands supplied by Jundu can be checked by visitors at the stand of the company at the Metalurgia expo. The line of products includes Industrial Quartz Sands (Base Sands) and Resin Sands to Shell Molding Foundry Process.
The foundry sands supplied by Jundu are extracted from the beds of the company, abundant and with ores of excellent quality. They are sold in bulk or packaged, with different options of granulometries and resistance levels that meet the specifications of the processes used in the manufacture of sand cores and molds.
To assure the quality and technical requirements specified by the market, Jundu has a strict quality control, which starts in the mine prospection. Using a specialized software, it is capable of defining the prospection criteria with control and optimized to all options of foundry sands.
Jundu is also distinguished in the provision of technical services by a team of experienced professionals and laboratories equipped with all resources. The company also counts on a modern laboratory to test the application of its foundry sands, being the only one in the national scenario among all sand foundries capable of assuring an exclusive result to customers.
The concerns and actions of Jundu are not restricted to the productive cycle, stretching beyond legal requirements. The entire production of the foundry sands is surrounded by environmental care. The waters used in the productive process are treated, stored, and almost completely reused in the productive process and the extraction areas are carefully rearranged and reforested with native species.
Aware of its socio-economic importance, JUNDU develops its activities focused on the safety and quality of life of its collaborators, and extends its concern to the community by means of social and cultural actions that integrate the company with the communities surrounding its industrial plants.
For over 60 years, Jundu has been focused on the innovation and improvement of its products to Customers in Brazil and overseas.
With a solid background in the prospection, treatment, and industrialization in large scale of non-metallic ores, the company produces and sells industrial quartz sand, resin sand, ground silica, calcitic lime, and dolomite.
In addition to offering the best solutions in sands for the manufacture of cores and molds (base sand and sand for the shell molding process), its products supply other major markets, such as the glass industry, ceramics, abrasives, filters, sports pitches, chemical products, fracturing operations in oil wells, among several others.
The Foundries are served by two main plants, located in the cities of Analândia/SP and Descalvado/SP.
Jundu was a pioneer in Brazil to extract industrial sand in mine out of a beach environment or river beds, and since 2002 it is formed by a Joint Venture between the French group Saint-Gobain and the Belgian group Sibelco, acting in the market of non-metallic ores for over 147 years. This merge resulted what is today the largest supplier of non-metallic metals for foundry and glass industries in Brazil.
