Husky’s mold technology is built upon years of design
experience paired with new product innovation.
Husky offers many technologies to increase cavitation,
reduce cycle times and produce better molded parts.
STACK MOLD BASES
We have pioneered stack technologies since the 1970s. Our
stack mold bases feature balanced hot runners, robust link-
age systems and rugged mold supports. Mold base plate
actuation can be controlled through compact pneumatic or
hydraulic systems and/or rocker arms in order to meet part
ejection requirements. Husky’s stack mold bases substan-
tially increase output while maintaining cycle times and part
quality. In addition to conventional 2-level stack mold bases,
Husky also offers the following stack technologies:
Four-Level Stack Mold Bases — four-level stack molds virtually
quadruple the output of an injection molding machine, with
minimal increase in clamp tonnage relative to a single-face
mold. Husky’s 4-level systems utilize dual sprue bars control-
ling melt flow to both hot runners as well as a primary and
secondary harmonic linkage system for advanced mold open-
ing. Four-level systems are effective for parts with compatible
part heights and shot sizes requiring simple ejection systems.
4-level stack molds quadruple output, without significant increase in clamp tonnage.
Stack platens convert similar individual molds into a single-stack mold.
Stack Platens – The stack platen permits the consolidation
of two single-face molds in one injection molding machine.
This system delivers melt to a center platen via an offset
sprue bar. The center platen is configured with a Euromap or
SPI interface and transports melt to either side of the platen.
This allows two similar individual molds to function as a sin-
gle-stack mold, increasing machine output, reducing floor
space requirements and utilizing existing tooling.
