Spiraling raw material costs and quality requirements are forcing manufacturers to maximize energy and resource efficiency in processing EPS. Thanks to its technology leadership, HIRSCH Maschinenbau succeeded in setting the industry benchmark with the batch vacuum preexpander back in 1985.
Now the HIRSCH Innovation Center is presenting another global innovation. True to the corporate motto of “Expanding with Ideas”, it has developed the first batch and therefore particularly efficient preexpander for manufacturing EPS chips. The material made from recycled polystyrene is mainly used in the construction industry where a uniform product quality is required.
The prototype for the batch loose-fill preexpander was developed for an American group. Given the new development, EPS chips can be laid round the drainage pipes instead of stone chips to prevent silting.
Compared with the continuous technology previously widespread on the world market, the HIRSCH solution has the advantage that the new HIRSCH loose-fill expansion process operates fully automatically and processes the raw material particularly efficiently.
Together with the American group HIRSCH offers not only the know-how of this technology but also the according raw material, in order to get the complete production process from one single supplier.
