Thermal Plastic Cooling :: Isobar® Heat Pipes - For Electronics Cooling Devices :: Back to Services

Within the context of thermoplastic molding, the unique heat transfer characteristics of the Isobar® super-thermal conductor, when designed into the mold, ensure that energy build-up on the mold face is rapidly directed to the mold's cooling channels. The result is faster, more uniform cooling to the entire mold surface, which allows for shorter molding cycles. Rapid, uniform surface cooling also eliminates hot and cold spots on the working face, which in turn results in molded parts that are free from short shots, irregular shrinkage, and molded-in residual stress and warp.
It is not necessary to have the Isobar® in direct contact with a waterline to effect cooling; although Isobars® can be incorporated into the cooling channel, in many cases they need only be in proximity to a water line to promote effective cooling. This capacity allows the mold designer greater flexibility for positioning cooler lines in locations remote from complex core and cavity inserts, thus simplifying tool design and eliminating seals required to prevent coolant leakage. Water lines that are uninhibited by bubblers and bafflers also permit faster turbulent flow that minimizes mineral deposits and promotes a higher level of effective heat removal. The result: more efficient and effective cooling.
Furthermore, because Isobar® systems eliminate the need for bubblers and baffles which are associated with such problems as o-ring leakage, mineral build-ups, pressure drops, uneven cooling and complex water line designs, maintenance requirements and problems - which can result in unscheduled downtime - are significantly reduced or eliminated.
