that can be re-used back into their production
operation. The company is conducting a
higher number of material trials for customers
and as a result the number of orders for
recycling systems is greater than this time last
year. After lengthy discussions with a wide
range of processors from around the world
Munchy can state that the main contributory
factors to this increased interest in recycling is
due to the heavy rise in production costs
mainly caused by the price of polymer, rising
energy bills and increased transportation
costs. With machine payback in
approximately one year or less in some
cases, processors are making the investment
now in order to remain competitive. The
launch of Muncher has also been a
contributory factor in enabling organisations
to maximise their full scrap potential. The
Muncher’s ability to recycle a wide range of
material forms makes it more appealing than
traditional recycling systems that were aimed
primarily at the blown film and sheet
industries.

Hot Runner Technology
Products
GÜNTHER Heisskanaltechnik, a leading
supplier of hot runner systems, introduces its
new products and further developments at
EuroMold in Frankfurt, Germany. Nozzles with
the Octa-Flow type sub-distribution for side
gating in 1- to 8-fold applications are one of
the further developments of the manufacturer.
The nozzles require no split insert. The tips
can be changed individually. A heated sub-
runner provides for an optimised temperature
profile. Thanks to their floating bearings the
nozzles can be operated independently of the
thermal expansion. This makes it possible to
obtain extremely small gate diameters even
with large nozzle lengths. Also new in the
product range are the SDM type multi-tip
nozzles in the Z version for vertical gating
(picture). The nozzles allow a gentle melt
flow; the nozzle tips are regulated separately;
