Due to the supply of Espal, the mold strength improves, allowing for a reduction in the amount of resin added!
"Espal #40L" is a suitable aggregate for replenishing sand in self-hardening resin lines. Due to its excellent crush resistance, it improves the recycling yield and reduces dust generation. Since it does not contain free silica, it contributes to improving the working environment at casting sites. It has a shape close to a perfect sphere, allowing for the production of molds with high strength, high density, and low thermal expansion. 【Expected Effects】 - Reduction in the amount of industrial waste and replenishing sand due to improved recycling yield - Improvement of the working environment due to reduced dust generation and free silica content - Prevention of bending defects due to reduced thermal expansion - Increase in mold strength and prevention of burning defects due to improved fillability *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.
