Good core making begins with high quality core sand preparation. To meet the demands of modern core making facilities, Simpson Technologies has designed the new CSM Series Core Sand Mixer. The result of three years of development under laboratory and prototype testing, the new CSM Series is the most accurate, versatile and productive core sand preparation system available in the world today.
Chemicals are the most expensive part of prepared core sand.
To minimize consumption of expensive binders, it's important to have a highly accurate and reliable binder measuring system and to prepare only as much sand as needed. This eliminates unnecessary costs by assuring that the precisely requested amount of binder is always delivered to the mixing system. Plus, added confidence is provided by requesting the minimum amount of binder necessary for the desired core strength. The CSM Series provides binder proportioning accuracy to less than 1.0 percent error and, in actual foundry production, has demonstrated the ability to control to within 0.25 percent of set point. But accuracy in binder proportioning is meaningless if the sand proportioning is not equally capable.
