"How to Use Sand: Currently Seeking Enthusiastic Praise" Sand Creates Things

Our company is exploring "what can be done with sand"!

Sand is used in various applications, starting with industrial products, but our company is further exploring "what can be done with sand." We welcome any ideas, whether it's "I know of a way to use it!" or "Can it be used for this?"—anything that seems feasible or even a surprising thought is welcome. We are actively seeking innovative uses for sand! Please share your ideas with us. 【Examples of Sand Usage】 ■ Casting: Aggregate for molds ■ Glass and Ceramics: Glass tableware, heat-resistant glass ■ Building Materials: Wall materials, roofing materials, insulation materials, paint materials, roadbed materials ■ Steelmaking: Sliding nozzle sand for steelmaking ladles ■ Blasting: Paint removal blasting material ■ Others: Combustion aid for incinerators, etc. *For more details, please feel free to contact us.

Low expansion high strength artificial aggregate "Sangreen"

Due to the extremely low thermal expansion rate, it prevents cracking and deformation of the mold! High dimensional accuracy in casting production is possible.

"Sangreen" is an artificial sand processed from by-products generated during ferronickel smelting, with MgO and SiO2 as the main components. Using our unique technology, we have applied beneficiation treatment to improve the particle shape and surface. It is suitable for shell molds and is effective in the production of complex-shaped molds such as hydraulic components. This product possesses the necessary "high strength" and "low expansion performance" required for mold aggregates. Please feel free to consult us when you need it. 【Features】 ■ Unique beneficiation technology and stable supply ■ Achieves high strength and easy disintegration with low resin ■ Low thermal expansion rate improves dimensional accuracy of molds *For more details, please download the PDF or feel free to contact us.

Alumina-based spherical aggregate "Espal"

Excellent crush resistance! Contributes to improved yield during recycling (reduction of waste) and enhancement of the work environment.

"Espal" is an alumina-based spherical aggregate that can be used as a substitute for zircon sand and chromite sand due to its high thermal conductivity and significant heat absorption capacity. Its round and nearly spherical particle shape provides good flowability of the sand, improving the filling ability and strength of the mold, contributing to the improvement of casting surface roughness and prevention of galling. Compared to silica sand, it clearly exhibits a higher strength level and is effective in preventing gas defects by reducing the amount of resin added. [Features] ■ Round particle shape ■ Dense particle surface with minimal irregularities and smooth ■ Excellent collapsibility ■ Low thermal expansion rate ■ Excellent crush resistance ■ High thermal conductivity and refractoriness *For more details, please download the PDF or feel free to contact us.

Artificial aggregate "Magsand"

Golf course floor sand, topdressing sand, and snowmelt insulation! Promotes early sprouting of grass in spring and maintains green leaves in autumn.

"Magusand" is a product made from artificial aggregates that exhibit a black-gray color, designed for use as floor sand, top dressing, and snow melting insulation on golf courses. It possesses excellent features not found in conventional natural sand. The granule size is adjusted for good permeability. Its specific gravity is slightly heavier than regular sand, making brushing easy. It undergoes high-temperature drying, making it sterile and free from weed seeds. Additionally, it does not leach harmful substances. 【Features】 - Prevents frost damage in winter and is recognized for its snow melting effect. - Promotes early sprouting of grass in spring and maintains green leaves in autumn. - Encourages good root establishment and revitalizes grass. - Enhances the vivid color of grass blades. *For more details, please download the PDF or feel free to contact us.*
