We would like to introduce the high-performance artificial aggregate recycling system "Espal R," handled by Yamakawa Sangyo Co., Ltd. Due to its round and smooth particles, it achieves high strength with low resin and eliminates the need for sand baking. Additionally, it has low thermal expansion, significantly reduces bending, and improves dimensional accuracy. The high-performance artificial aggregate enables energy-saving and labor-saving in the casting process, and our system efficiently recycles it, promising increased productivity and reduced costs. 【Features】 ■ Shortens the casting process - No sand baking required - No rework needed - No cooling wait required ■ Collects shell sand and carbonized sand - No industrial waste disposal costs *For more details, please download the PDF or feel free to contact us.
