enables maximum heat dissipation from the cylinder
to the cold platen.The many advantages derived from
using HRScool come about because there is no longer
any need for elements such as cooling lines, channels
and connections that are otherwise necessary for
active cooling. Consequently, assembly and handling
costs are reduced. Machine availability increases
because problems with clogged cooling circuits and
the degradation of hydraulic fluids can no longer occur,
thereby lowering operating costs. Furthermore, the
compact design of systems with HRScool takes up less
