Isobar® Heat Pipes in Standing Cores
Acrolab's Isobar® Heat Pipe technology can be used in standing cores
for rubber heating by providing a high-speed isothermal path for
thermal energy to travel.
In a comparison test performed using a sold steel core pin and a core
bored out to accept an Isobar® Heat Pipe, it was shown that the
Isobar-infiltrated core reached steady state in approximately half the
time required for the solid steel core. Secondly, the steady state
temperature of the Isobar-infiltrated core is 40 percent higher than
the solid steel core.
The installation of Isobar® Heat Pipes in standing cores, either singly
or in multiple arrays, allows the molder to resolve the difficult
processing problems such as uneven core heating and low-temperature
recovery that directly effect cycle time and uniform cures.
Isobar® Heat Pipes provide the thermal linearity necessary to achieve
uniform molding conditions on all molding surfaces. Deep cavities and
standing cores will become much easier to cure uniformly with the
installation of Isobars. The entire cure cycle will be exposed to
Installation of Isobar® Heat Pipes may result in recovery of old face
temperatures in up to half the time when compared to traditional
heating and conduction methods.
