High Temperature
Materials
by Doug Palmeter, Senior Processing
Engineer
I was surprised
to learn that the #1 hit on our website is “High
Temperature Materials”. We tend to run these materials every day and have
come to take them for granted. I guess we shouldn’t, because
it sure seems like a lot of people need that expertise.
What
are High Temperature Materials? Everyone has their own
definition, but at Ironwood Plastics they are materials that
require mold temperatures over 200F and melt temperatures over
600F.
Materials included in
this category are:
·
(PEI) Ultem
·
(LCP)
Vectra
·
(ETFE) Tefzel
·
(PPA)
Amodel
·
(PPS)
Ryton, Fortron
·
(PES)
Radel
·
(PEEK) RTP,
Thermocomp (Medical grade
also)
·
(PSU) Udel
Dealing
with these materials
requires a different mindset. For instance, molds are heated initially
to 275F. They are then thermally regulated to maintain the
tool steel at steady state temperature using pressurized
circulators that can reach 400F. Braided supply and return
lines, outfitted with connectors that have high-temp o-rings
and safety clips, are needed. Molds must be insulated on the top
and bottom to keep the heat from escaping the mold.
Ironwood Plastics is also known
for its insert molding capabilities. Six-axis robots load inserts into a mold
approaching 400F. Before robotics it was dangerous, if not impossible, to
load molds with such temperatures.

Ironwood Plastics
Holds National Sales
Meeting
Ironwood
Plastics held its National Sales Meeting on October 11-13,
2007. Four agencies representing Ironwood Plastics in 20
states attended. The following is a letter from one
agency:
Mark,
The recent national
sales meeting at Ironwood Plastics was a complete success! Our agency is
excited to present customers and prospects the news of your
highly integrated production cells, the high-tech white room, and of
course, the additional capacity. The ability to design,
develop, and produce integrated production cells
gives Ironwood Plastics a competitive advantage in
our targeted markets.
We have seen many technical developments at Ironwood
Plastics over the course of our 20 year relationship, but none
as impressive as the integrated production cell
capabilities.
Ironwood
Plastics truly has taken their slogan, “Challenge
Us”, very seriously.
Thank
you,
Charles
J. Librizzi
Librizzi
& Associates
Note: Librizzi & Associates has
represented Ironwood Plastics for over 20 years in
the states of Michigan,
Illinois, Wisconsin, Iowa, Ohio, Indiana and Missouri
