DISA sand processing system has multiple temperature and humidity monitoring points which can realise constant monitoring for the sand. Meanwhile, we have online detector for the casting sand. Each batch of sand will be detected first after being mixed. If qualified, then it will be used. Otherwise, automatic mixed again till qualified.This technology can gurantee that every batch sand will be qualified and the quality of the casting sand is stable and uniform so as to ensure the stable quality of the casting parts.
