Stork IMM's global fl ight
comes to roost in US
By Catherine Kavanaugh
Plastics News Staff
Hengelo, Netherlands-based
Stork Plastics Machinery BV announced
at K 2019 that it was
reinvesting in North America
to support its customers in the
packaging market. Three years
later, a subsidiary called Stork
IMM USA has a headquarters
near Philadelphia, stocked with
local spare parts and looking for
a national sales manager.
" We have a building and a home.
There's concrete underneath the
business, and we have invested in
in-country service with aftersales
personnel based in North America
to visit and see customers.
We don't fl y people from Europe
anymore, " said Benjamin Sutch,
managing partner of Chudleigh
Sutch UK Ltd., which distributes
Stork's range of full-hybrid injection
molding machines in North
and South America.
The establishment of a U.S.
subsidiary brings Stork full circle.
The company entered the press
building business in 1968 under
license from Reed Corp., then a
major U.S. machine builder.
Stork later began making machines
from its own designs. The
company built on experience
that went to back to its founding
by the Stork family as a machine
works in 1868 in Hengelo.
At one time a publicly traded
company, Stork became completely
private last year with an
investor that supports the strategy
to expand to the U.S. market.
In North America, Stork offi -
cials plan to attend symposiums,
regional shows and NPE.
" We're getting ourselves back
in the thick of it, " Sutch said.
" Three years ago we were a European
company servicing North
American customers. We are
now an American company with
Dutch heritage. "
The subsidiary's focus is on
larger machines like the 700-ton
press molding 10-liter pails in a
two-cavity mold at K 2022.
" That's our sweet spot, but we
have a range from 200 to 2,000
tons, " said Wim Brinkman, regional
sales manager and a former
application engineer.
Stork customers produce pails,
crates, thin-walled food applications
and fl owerpots, often from
post-consumer recycled resin.
" The demands on the fl owerpot
machines are extremely
high, " Brinkman said. " The cycle
times are the lowest in the market,
and they work with the worst
material you can buy. It gives us
a big advantage because we have
the knowledge of how to reuse
[post-consumer] and regrind materials
- the things you sweep
off the fl oor, they put in our maSTORK

chines and make products out
of them. We have done that from
the fi rst day we started building
injection molding machines. We
have a lot of experience. "
Stork claims it was the fi rst
machine builder with a full digital
control, which was developed
in 1995, according to Brinkman,
who has been with the company
for 35 years.
Reducing energy consumption
is another critical issue for processors,
especially in Europe,
and Stork has a lot of history in
this pursuit as well, Brinkman
said, pointing to what he called
" a very special clamp drive. "
The company uses a double-sided,
rack-and-pinion system instead
of a ball-bearing system, which ultimately
lets them turn the motor
into a power generator that returns
electricity to the grid or another
machine when the machine opens.
" The spring energy stored in
the tie bars that is released when
unlocking the mold is fully recovered
and fed back into the grid, "
Brinkman said.
Some machine builders direct
the stored energy back to the
same press, but Brinkman said
it's best to export it to the grid or
a neighboring machine, where it's
more useful.
" That gives us 30 percent lower
energy consumption than the
next best competitor, " he said,
adding the fi gure was measured
by a big customer in Europe that
put presses from fi ve machine
builders to the test.
" They did settings and measurement
of all fi ve companies,
and after a month they came back
and said you're by far the best,
and they bought a few machines, "
Brinkman said. " They were totally
convinced. "
Stork engineers analyzed the results
and determined the difference
was sending the power back to the
grid or a neighboring machine as
opposed to the same press.
" So it's like having your own
power generation system in your
factory, " Brinkman said.
The system also eliminates the
costly need to replace worn-out
spindles and balls, he added.
For these reasons, Stork's
full-hybrid machines, which have
electric clamping and electric
plasticizing, use less energy than
all-electric machines or general
hybrids, Brinkman said.
Brinkman also noted that Stork
presses have three standard parallel
injection valves as opposed
to bigger valves, which are specialized
components.
" When you go from speed control
to pressure control, big valves
aren't fast enough or accurate
enough for the very sensitive pressure
control, " Brinkman said. " We
switch three valves on high speed
and then switch two valves off
during the changeover so we have
full control of the pressure and
very low speed at the end of injection
during the holding phase. "
This is critical to producing a 100
percent good product, he added.
" It's really important to have
good control in that phase of the
process, " Brinkman said. " If you
don't control the molding, then
you don't control the shrinkage
of the product and the size. "
