Isobar® Heat Pipes resolve the difficulties in achieving thermal
uniformity within a core and from core to core in complicated
multicavity molding. Installing Isobar® Heat Pipes in tree-bars to
parallel cartridge heaters assures that the tree-bar itself is
isothermal. The tree-bar can now provide a common temperature to the
base of each core pin mounted onto it. These cores, in turn, achieve an
isothermal condition along their molding face when Isobar® Heat Pipes
are installed in them. In comparing temperature variations along the
length of a core mounted in a tree-bar orientation with and without
Isobar® Heat Pipes installed, it was observed that with Isobar® Heat
Pipes installed in both the tree-bar and the attached cores, each core
molding surface may be held at an optimum uniform molding temperature
without complex multizone temperature controls and the complex wiring
associated with large numbers of thermocouples and heaters. The Isobar®
Heat Pipe system reduces maintenance costs by reducing the overall
complexity of the mold heating system.
Isobar heat transfer systems permit the molder to maintain optimum
processing temperatures with a high degree of mold face thermal
uniformity and with an increase in energy throughout. This results in
faster cycle times with consistent, optimal cures.
