The ISOSPRUE™ Spreader is an integrally heated mold component which contains its own miniature precision thermocouple. This unique integrated thermal mold component can be heated and controlled to any discrete temperature to assure fast effective curing of the sprue resulting is shorted cycle times and safer mold cycling.

Integrally heated and controlled sprue spreader
One significant continuing challenge
associated with injection/compression
thermoset molding is predictable high
speed curing of the sprue section.
Acrolab’s unique integrally heated and
controlled sprue spreader provides the
solution.

Ø The ISOSPRUE™ spreader is made of D2 steel and
nitrided for toughness.
Ø The ISOSPRUE™ Spreader in integrally heated with
400Watts of power at 240 VAC allowing it to be easily
and directly incorporated into the control system typically
used to heat the mold.
Ø The ISOPSPRUE™ Spreader has its own internal and
replaceable precision type J thermocouple which permits
closed loop control to the resin’s optimum operating
temperature.

Ø The ISOSPRUE™ Spreader
is custom fitted to the stack
height of the tool by threading
it on to the end of a cut to
length hollow extension
sleeve typically and easily
made from an injector sleeve.
Ø The ISOSPRUE™ Spreader
incorporates an integrated
heating element swaged
directly into the tool blank
which is then shaped and heat
treated to become the final
geometry of the sprue
spreader.

A proprietary technology
provides a method for a
replaceable 0.020” type J
thermocouple to be located
within the ISOSPRUE™
Spreader’s tapered tip to
provide the close control
needed to produce the high
speed cure of the spreader
section.
