The starting point of the development of a Cold-Box process on polyurethane basis was the fact that the machinery heating required in the Hot-curing -Processes was considered to be a substantial disadvantage.

In the late seventies, the development of a humidity resistant Cold-Box System contributed decisively to the possibility of using water based coatings without any problems.

The importance of the Cold-Box-process is schown by the Fact that more than 57% of all cores in series foundries are manifactured according to the cold-Box-process

Since a thermally stable Cold-Box System was developed in the early nineties, even complicated cores like water jackets and oil galleries for the automotive casting industry - that used to be manufactured in Shell or Hot Box - can now be produced without any problems. Furthermore, it was possible, for the first time, to cast cores for series production in nodular iron without any additional coating while achieving good casting surface finish.

Since then a further development has been done in order to improve the technologicals proprieties and envirnomental issues of the following Cold-Box systems:

In 1996, Hüttenes?Albertus introduced a new patented environment-friendlier Cold-Box System.....

Aside from the problem of reducing pollutant emissions during production of casting, foundries are....

Many foundries already prosses or plan to apply DIN EN ISO 14001 Certification....
