CHEMEX Feeding Systems

Research and development in alliance with HA

Chemex is already a global leader in the field of feeder technology. Nevertheless, the company never rests on its laurels or stops researching and developing new products: As a member of the HA Group, Chemex has access to the extensive expertise of one of the world’s leading foundry chemistry suppliers. To offer customers even better solutions, the company’s research and development team is constantly working on and testing new materials and approving them for series production.

Sands, insulating materials, and exothermic components: every year, 10,000 tons of raw materials are processed in Delligsen. Each product variant has its own recipe, according to which the feeder mass is precisely mixed to the last gram. The compositions – some of which are patented – are what constitute Chemex’s expertise. The specific material formulations are what determine the eventual insulating and exothermic properties.

Consulting at the highest level

Chemex is justifiably proud of its close collaboration with its customers. Six foundry engineers put their knowledge and experience into practice to optimize the feeding technology and the cost structure of the individual castings on-site together with their customers.

Sustainable use of resources

Chemex is certified according to the environmental management standard DIN EN ISO 14001, so the company’s responsible and sustainable use of resources is well-documented. Core shooters, scrubbers, and compressors have been continuously updated since 2001 and are, therefore, always state-of-the-art. The company’s careful stewardship and use of resources are constantly monitored and improved.

Sometimes very small, sometimes very big

Based on individual calculations, feeders are specifically designed for each application. Chemex's extraordinary variety of products gives customers the perfect choice for their specific applications. The spectrum of feeders ranges from very small to very large, with volumes of over 11 liters.

Tested and certified quality

Chemex works with a quality management system according to DIN EN ISO 9001. The quality of the company’s feeders is tested using various methods, including thermo-physical testing. Parameters such as gas permeability and bending strength are also systematically monitored. Ignition and burning times are determined in an exothermic test.
