RCS has about 100 different brands depending on the type of sand, particle size distribution, type of resin, and amount added!
"Hyper Pack" is an RCS that coats the surface of sand grains with a thermosetting resin and is used as a casting aggregate in a special mold called "shell mold." It utilizes a two-peak particle size distribution instead of the conventional normal distribution, allowing for customization of particle size indices and blending with artificial sand. The second peak sand (fine sand peak) adheres immediately to the surface of the mold during blow filling, enabling the creation of a highly dense mold surface. [Features] ■ A wide variety of combinations ■ Possesses a meticulously calculated two-peak particle size distribution, achieving a high wall effect ■ Achieves mold filling rates comparable to spherical artificial sand ■ The mold surface is very dense, reducing the amount of coating required ■ In some cases, it is possible to eliminate the need for coating *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.
