As part of the measures for preventing casting defects, additives are a tried-and-true solution. A small addition, for instance, can remedy several common defects (e.g. surface-based defects). However, at ASK Chemicals we are advancing additive technology beyond common uses. Our engineers – working alongside our customers – are discovering speciality additives that can reduce the use of expensive sands and, in some instances, replace coatings entirely. Within cold box production, in particular, this revelation could reduce costs substantially and enhance productivity. Dimensional accuracy compliance is equally relevant where additives may substitute coatings in thin-walled castings. Ultimately, coating-free production offers reduced material costs alongside the elimination of peripheral coating equipment, resulting in major savings.
