Additive Technology

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.

At ASK Chemicals we provide innovation-driven research through our product development approach. We focus specifically on market trends and customer demands because of the increasingly complex requirements our industry is facing: reduced emissions, casting defect prevention, cost efficiency and overall casting quality. Such requirements necessitate more than just strong partnerships and outstanding technologies; rather, we believe that first-class research and development that focuses on efficiency, environmentally friendly solutions and key performance parameters is essential.

In addition, we offer you a holistic approach that goes well beyond merely offering products. Our application technology and technical sales specialists in particular always assess the production process as a whole. Only this approach allows for customerspecific solutions that are precisely tailored to meet your requirements.

Finally, our specialists' expertise is complemented by a broad range of services that offers you real added value. For example, our design services can be systematically deployed to optimize the process as a whole – from conceptual development to actual series production – thereby offering you important savings and process improvement.
