BOY to expand its range of efficient First COMPEO compounding

and compact Injection Molding system for color masterbatch in
Machines operation

OY announces the expansion of its range of efficient OMPEO 88 compounder from BUSS that was
Band compact BOY injection molding machines in Claunched in Ocotber 2019 is already in industrial
spring 2020 by launching BOY 35 E PRO (350 kN clamping use. The first user is a multinational masterbatch
force). With the new machine sets new standards from manufacturer, which has been producing color
63 to 1250 kN clamping force.According to the company, masterbatches with this system since late October
the machine is available with the SP 96 injection unit 2019. BUSS's technical center had previously optimized
and screw diameters from 24 to 32 mm. In addition to the screw configuration for this specific application
a highly wear-resistant thermoplastic unit (screw-Ø 24,
28 or 32 mm), the basic equipment of the special model
BOY 35 E PRO has an open nozzle with R 35 mm standard,
alternatively R ½ “. While the mould installation height
is decreased by 50 mm (150 instead of 200 mm), it
features an ALPHA ® 2 control procan.There are seven
additional options available including a handling-interface
according to Euromap 67, a core pull control and four
freely programmable inputs/outputs.Having a footprint
of 1.96 m², the compact, four-tie-bar injection molding
machine has a clamping force of 350 kN and is equipped
with the proven Procan ALPHA ® 2 touch control.The BOY – a service that is available to any customers with
35 E PRO is powered by an energy-efficient, servo-motor individual applications – so commissioning took just one
pump drive. It has a low energy requirement of less than week. The user had selected the COMPEO 88 following
0.49 kg/kWh (7 + corresponding to classification as per extensive series of tests on different compounding
the Euromap 60.1). In a practical application example, systems. One major factor was the particularly efficient
reference-measurements were carried out with other drive dispersion of the high contents of liquid components
technologies. The savings potential of the model of the E and color pigment typical of masterbatches. The
series with servo-drive recorded 8,700 kWh annually with liquid additives can not only be fed in together with
the premix in free fall via the large-area inlet but can
also be injected directly into the melt via injection
pins. Another decisive factor was the uniform shear
in the process section, which prevents temperature
peaks and thus enables precise temperature control
just above the gelling temperature of the sensitive
carrier material. The gentle yet emphatic pressure
build-up in the conical twin-screw discharge unit also
makes a significant contribution to achieving the stated
goal of high process consistency and thus uniformly
high product quality until formulation change. Due to
the large number of small lots with a wide variety of
6,000 operating hours p.a. This would save up to 4.67 tons formulations and colors that are typical of masterbatch
