Oerlikon HRSflow launches new stack mould system

likon HRSflow Test Lab. Customers
can run product trials with their most
challenging polymers. The Test Lab is
equipped with six injection molding
machines – from 50 to 1000 tons – this
aims to offer customers the possibility
to define the best hot runner configu-
ration for their specific applications.
The new Stack Mould has also been
developed to process PCR resins and
sustainable compounds according to
future needs which are increasingly
connected to Circular Economy.

Supramolecular polymers are a new
class of polymers that are currently
being evaluated for material applica-
tions. These interesting compounds
also play an important role in cellular
activities in the body. "Supra," as the
name suggests, is attributed to some
unique properties that go beyond
those of conventional polymers.
