product details
  • Exothermic-insulating sleeves are used to increase the yield in foundry practice. Function of the sleeve is predominant to enhance the effective casting modulus by increasing feeding efficiency. This is represented by a modulus extension factor (MEF) and shrinkage porosity of the casting. The use of an exothermic-insulating sleeve as a substitute for sand feeder can increase efficiency by up to 60%. However, exothermic-insulating sleeve in use today is imported and has limited range
