Genuinely Utilizing Recycled Sand, As Sand Resources Is Limited And Precious Recycling Casting Sand for Environmental Preservation

Tochu, the first company in RCS industry in Japan, have developed a remarkable recycling system which enable us to preserve this limited source-sand.
Tochu has put considerable efforts into recovering and recycling casting sand used by customers.

There are two types of recycled sand, the first system transforms used sand into new casting sand and the second system produces resin coated sand from used sand by coating phenol resin directly or by blending with new sand.
The recycled sand has high quality, almost the same as that of natural sand.
Since the recycled sand has excellent quality in terms of Strength, Fluidity and Thermal expansion characteristics, it also has large cost merits.
The recycled sand is expected to be casting sand of the 21st century.
