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
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.
