intricate layouts of water cooling lines and requiring thicker
cavity plates that can provide needed support for the mold.
Thermally insulated manifold supports are now available, as
are gate cooling inserts that make it easier for moldmakers
to get water to the gate areas.
PCS's Tim Markham believes cast manifolds will be the
wave of the future. "This will give designers the ability to
create better balance in the flow channels, with fewer dead
areas that can trap degraded resin, and
it will enable better color changes,"
he says. Sudheer Thrissileri of Mold-
Masters adds that due to the weight
reduction of molded parts,
the need for faster cycle times and
molds that are expected to run mil-
lions of cycles, the robustness of
molds becomes more critical. "The use
of alloy steels and special coatings for
steel that can withstand many years
of production will become more the
norm than special," he says.
Incoe's Jim Bott says to look for
solutions that will improve melt-deliv-
ery performance over what is currently
available and in a smaller footprint.
"This will provide the mold builder
with more real estate to implement
mold heating and cooling technolo-
gies," he says. It will also be possible
to reduce or simplify mold machining,
he adds. Hasco's Brenda Clark says
that spare parts for manifolds, nozzles
and heaters are becoming more stan-
dardized and easy to access when
changeouts are required, such as when a problem arises
or simply because of normal wear and tear on the system.
Standardization will also help designers design a better
mold and give moldmakers critical sizing details for more
accurate machining that can alleviate fit or leak issues.
"This also will advance the manufacturing of more reliable
systems and hot halves for all end users," she says. "Good
information in equals great production out!"
