PLASTINUM Foam
PLASTINUM Temp
Foaming with carbon dioxide
Today, many blowing agents used in the production of foamed polymers such as building insulation (XPS boards) and packaging (high
density PE foams) contain a high percentage of carbon dioxide. Exact
metering of liquid carbon dioxide (LIC) plays a key role in the quality
of the foamed product. Achieving this can be a challenge, however,
particularly given counter-pressure variations in polymer extruders.
For advanced temperature control
Areas such as mounting points or reinforcement webs in injection
moulded products are not always accessible with standard cooling
water channels. As a result, these “hot spots” are barely cooled and
require longer times to cool down, slowing down the entire process
flow. We have developed a range of sophisticated PLASTINUM temperature control solutions to access these areas and ensure uniform,
accelerated cooling.
PLASTINUM Foam E
Extrusion foaming with carbon dioxide
Our PLASTINUM Foam E portfolio was designed specifically to meet
the metering challenges of LIC foaming systems. Our patented, proven high-pressure gas supply and metering system DSD 500 responds
extremely quickly to changing counter-pressures to keep the mass
flow of carbon dioxide constant for uniform, predictable foaming
results.
PLASTINUM Foam P
Solutions for polyurethane foaming
Designed specifically for polyurethane foaming processes, our
PLASTINUM ­Foam P solution helps manufacturers ensure consistently
high quality standards. Our special supply pumps are engineered
to deliver the high volumes of liquid carbon dioxide needed to produce low-density foams used in mattresses for instance. Especially
for non-continuous processes, our dedicated metering systems supply liquid carbon dio­xide with extremely high accuracy.
PLASTINUM Temp S
Spot cooling for injection moulds
Our patented PLASTINUM Temp S solution uses liquid carbon dioxide
(LIC) as an effective cooling medium for hot spots. Using the su­perior
cooling power of carbon dioxide as it expands, PLASTINUM Temp S
reduces cycle times by up to 50%. Comprising control devices, distributors and capillary tubes, our spot cooling package can be easily
retrofitted to existing installations.
All-in-one package.

PLASTINUM Temp D
Dynamic injection moulding with carbon dioxide
Our PLASTINUM Temp D solution increases the efficiency of dynamic
injection moulding by using carbon dioxide as a heat carrier. This
allows manufacturers to install both the mould heating and cool­ing
systems in close proximity to the mould surface and thus minimise
cycle times. For cooling, LIC is supplied from cylinders or bulk tanks
and expands in a system of tiny channels provided with mould
inserts. For heating, hot gaseous carbon dioxide is pushed through
the same channels in a closed cycle. This compact design translates
into added cost and environmental benefits.

PLASTINUM GIM
PLASTINUM GIM I
PLASTINUM GIM P
Gas injection moulding (GIM)
GIM relies on high-pressure gas (carbon dioxide or nitrogen) to
shape a hollow or channel in a moulded plastic part. Popular in the
automotive industry in particular, this process allows manufacturers
to produce lighter plastic components with higher dimensional
accuracies. We offer a range of highly efficient, dedicated solutions
to supply high-pressure gas to GIM processes. Our PLASTINUM GIM
portfolio is designed to take process efficiency and quality to the
next level.
Gas injection moulding with inner cooling technology
PLASTINUM GIM I enhances the efficiency of traditional GIM op­­
erations by adding a patented inner cooling process step. Here,
high-pressure nitrogen is pushed through the component, accelerat­­­ing cooling cycles by up to 50%. Advanced injector technologies
complement our PLASTINUM GIM I solution for even greater process
efficiency.
Purging of cavities and hoppers
PLASTINUM GIM P is an innovative method to purge cavities with
an inert gas prior to polymer injection. It enhances quality and
productivity by reducing downtime and maintenance effort as a result
of dirt caused by oxidation. It does this by supressing the formation
of undesirable oxides, which often lead to clogging of injectors and
lengthy downtime.
PLASTINUM GIM C
Gas injection moulding with carbon dioxide
PLASTINUM GIM C takes efficiency to the next level by replacing
nitrogen with carbon dioxide (CO2). While matching the heat removal
capacity and cycle times of water injection moulding, carbon dioxide
does not leave any moisture on the products or tools, thus eliminating
an additional drying step in the fluid injection cycle. We deve­l­oped
our PLASTINUM GIM C fluid control units and injectors in close collaboration with our OEM partners.
