Home Products Risers ECO-Riser®


go to Toolbox

The ECO-Riser® is a combination of an exothermic inner riser shell and an insulating outer shell that reduces the heat lost to the surrounding molding material, this significantly improves energy efficiency. The improved energy efficiency allows for reductions in exothermic mass necessary and at the same time increases the effective modulus of the riser, improving product efficiency.

This feeding system has been consistently further developed during the last four years in collaboration with Georg Fischer (Leipzig) and there is now a variety of ECO-Risers® available in the series with module ranges from 1.9 cm to 4.5 cm.

Increasing energy efficiency in feeding systems

Foundries and their supplier industries cannot ignore the global trend towards using resources more efficiently and optimizing the performance of raw and auxiliary materials. Given the energy intensity of foundry production processes, considerable energy savings can potentially be found. The ECO-Riser allows.
