Isobar® Heat Pipes in Standing Cores

Cross-section diagram of core with and without Isobar Heat Pipes 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 isothermal conditions.
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.
