Chemex GmbH, a wholly-owned subsidiary company of Hüttenes-Albertus Chemische Werke GmbH (HA), was established in 1974, and has since then evolved into one of the most important suppliers to the foundry industry. Chemex is worldwide represented by the marketing organization of its parent company HA.
The exceptional variety of our products assures our customers an optimal selection of feeding systems. The ultramodern fabrication method by means of the cold box binder systems in combination with the innovative and patent-registered Teleskop-Speiser® (Telefeeder) technique represents a specialty in the area of feeder technology.
Besides the feeder technique we also offer a multitude of high-quality melt-treatment agents for the nonferrous foundry industry.
Our product managers in close cooperation with our research and development department, continuously update and optimize our products to enhance their utility to the foundry industry.
We consider it as our commitment delivering our customers competitive products at the highest quality stage by granting an economic casting production at state of the art. As a matter of course we are DIN EN ISO 9001 and DIN EN 14001 certified.
Our high-quality products are being manufactured at two locations. Our headquarter in Delligsen near Hanover produces CB-bonded feeder sleeves for our customers throughout Europe. Our subsidiary company HA Kovochem in Mnisek pod Brody, Cech Republik, produces feeder sleeves by means of conventional binding systems, e.g. slurry and sodium silicate binder technique.
