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.

Company information
Global warming caused by carbon dioxide and serious air pollution due to PM2.5 are becoming environmental issues that can no longer be solved by a single country; they are now global problems. Until today, Yamakawa Industries has contributed to the development of related industries, including the casting industry, primarily through various processing of sand resources. However, now that we are faced with such a critical situation on Earth, we must return to our origins once again and, with an unyielding frontier spirit, "pioneer the next new era." With this determination, we must work together to tackle the conservation and regeneration of the global environment. As a specialist in sand, Yamakawa Industries bears part of the social responsibility for the regeneration of limited Earth resources from the standpoint of environmental conservation and effective resource utilization.
