型砂试验仪器是用来测定铸造用原砂、型砂及芯砂的基本性能的仪器。它对提高铸件质量、减少铸件废品率,起着重要的作用。一九七五年一机部仪表局责成沈阳铸造研究所组织有关科研单位、高等院校、制造厂成立联合设计组,对原型砂试验仪器进行更新,并研制新的型砂试验仪器,以适应铸造行业日益发展的需要。经过三年的共同努力,原型砂 Sand testing equipment is used to determine the basic properties of foundry sand, sand and sand core. It plays an important role in improving the quality of castings and reducing the reject rate of castings. In 1975, Bureau of Bureau of Bureau of Machine-building instructed Shenyang Institute of Foundry to organize relevant design institutes, universities and manufacturing plants to set up a joint design team to update prototype sand test equipment and develop new sand test equipment to adapt to casting The growing needs of the industry. After three years of joint efforts, prototype sand
