Innovative Feeder Technology

Our subsidiary, Chemex Foundry Solutions GmbH – Chemex for short – supplies customers around the world with a wide range of state-of-the-art feeder systems. Chemex was founded in 1974 and has gone on to become a global technology leader for feeder systems.

The Chemex team is dedicated to collaborating closely with customers to optimise their castings through precisely matched feeder systems, increase output, minimise separation and fettling costs and constantly refine recipes and feeder geometries.

A strong team of product managers is on hand at all times to provide optimal service for customers, including expert advice on the company’s standard portfolio and the development of tailor-made solutions.

The strengths of Chemex feeders

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. With the aim of offering customers ever better solutions, the company’s research and development team is constantly working on and testing new materials and approving them for series production.

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 optimise 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 is constantly monitored and improved.

Patented expertise

Sands, insulating materials, 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 very 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.

Sometimes very small, sometimes very big

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

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 a range of 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.

The mobile Chemex App

With this application for your smartphone or tablet you benefit from many advantages. On the one hand, the product finder enables you to quickly and easily find the right product depending on your moulding process and the alloy to be cast.

On the other hand, products featuring an AR symbol in the catalogue can be displayed in 3D. With the help of modern Augmented Reality (AR) technology, the respective 2D drawings are also displayed in 3D.

As an innovative partner Chemex would like to support you in your everyday routine by providing this service in the best possible way. This is another step towards the digital future. If you have any questions regarding use, suggestions or recommendations for improvement, please contact your responsible product manager or write to us at
