Keracron®-Precoated Molding Materials
- Very low coefficient of linear thermal expansion
- For manufacture of castings that are free of finning
- Peak dimensional accuracy of the castings
- High (above 1,800 °C) temperature resistance
- Very easy core shakeout after pouroff
- Also supplied as through cure-accelerated, precoated sand
| The KeraCron® precoated molding materials developed at HA have been specially designed to meet peak foundry demands, for example in production of hydraulic castings. Their excellent flow properties and mold filling capabilities permit molding of fine detail not possible using any other coremaking process. Their systematically adaptable thermal expansion properties make it possible to prevent a variety of casting defects, thus affording a marked reduction of the finishing costs in the foundry. |
