CX series
The CX series covers the small and
medium-sized clamp force ranges. It is distinguished by its
high flexibility, cost effectiveness and high part quality.
CX series machines are available in clamp forces from 350 to
6,500 kN. In coming months, the CX series will be
continually expanded up to clamp forces of 4,200 kN.
Principle
At the heart of the CX series is the consistent further
development of the innovative twin-platen technology
introduced by KraussMaffei. The series is modular offering a
large number of possible combinations. The advantage for
customers is that they can find a machine solution suitable
for their specific production requirements in the
KraussMaffei programme. They can put together their own
tailored machines from more than 100 possible combinations
of clamp units and injection units. KraussMaffei also offers
an extensive catalogue of functions with a large number of
further options that you can easily retrofit according to
requirements:
- Injection pressure up to 3,000 bar
specific
- High-temperature plasticizing up to
450° C
- High screw speed (hydraulic)
- Electrical screw drive
- Parallel operation for ejector/core
puller
- Pressure accumulator for enhanced
injection performance
- Technology packages for processing
thermosets, polyesters and silicone
- Hot-runner and cascade control
- Process-engineering control
extensions
- Options for process control and
internet connection
Technology
The impressive characteristic of the CX series are the
four clamp cylinders that introduce the clamp force
absolutely symmetrically and ensure uniform clamp-force
distribution. The all-hydraulic clamp system with integrated
drive cylinders ensures rapid, dynamic opening and closing.
Twin-platen clamp unit
The twin-platen clamp unit from KraussMaffei is compact
and fast, requires low maintenance, prolongs the mould life
and ensures excellent platen parallelism. It also offers
generous space in the ejector zone. The free clamp system
behind the moving platen makes it easy to reach into the
ejector zone during tool set-up and adjustment. The
twin-platen clamp unit makes it easy to perform special
processes or meet special requirements. The outstanding
accessibility in the clamp area is ideal for the integration
of automation solutions.
Injection technology
The CX series offers the correct injection unit and
optimum screw design for any production task. The
plasticizing screw is required to meet exacting performance
requirements. It must deal with continual increases in
plasticizing rates, keep melt temperatures low, improve
mixing and homogenization rates and cover new processes that
stretch the processing window.
KraussMaffei meets these challenges by offering mixing and
high-performance screws (HPS-UN and HPS AT) in addition to
our standard screws. We also have special screw and
plasticizing solutions for special applications such as the
processing of long glass-fibre-reinforced or crystal-clear
polymers. The CX series offer a powerful injection unit that
does not stress the material and is low wear.
Hydraulics
The CX series features a precise, flexible and modular
hydraulic system. It is characterized by an economical
control pump drive, rapid responses and reliable control
valves. The hydraulic components are connected to the
centralized machine control via state-of-the-art bus
technology. Effective, rapid and reliable data processing
ensures optimum machine availability and product quality. To
boost machine performance, the hydraulic system can be
easily retrofitted with accumulators and additional pumps. A
new oil-filter concept with filter of the primary and
secondary streams ensures that the hydraulic oil has a long
lifetime.
The product portfolio is rounded off with hybrid drive
concepts including an electrical screw drive, electrical
injection unit and electrical ejector.
Control system
All CX machines are equipped with the MC 5 microprocessor
control system. The control is easy to operate and avoids
input errors. It features a straightforward, clearly
presented display, with the important information
highlighted. All the most important control parameters are
easily accessible, assigned to functions and permit
sensitive process control even for complex sequences of
machine operations.
Customer
benefits
- The compact twin-platen clamp unit
from KraussMaffei saves space and prolongs the mould
life. That increases productivity of acceptable parts
and part quality.
- The new optimized cladding ensures
excellent accessibility, and increases transparency of
troubleshooting This can reduce machine adjustments and
set up times and increase machine availability.
Servicing and maintenance can be carried out quickly and
easily. · The larger dimensions (optional) permit higher
mould weights, larger platen dimensions and opening
strokes. Stack moulds and multicavity moulds, and
complex technologies can be used.
- Plasticizing units with extremely
long service lives optimize melt quality and process
stability and increase throughput. The standard
plasticizing unit is suitable for a wide range of
applications. Wear is minimized.
- The improved hydraulic and
electrical systems reduce consumption of energy and cold
water. Average energy consumption is only 25 percent of
the installed power. The oil sump integrated in the
machine bed is environmentally sound, since no oil can
escape. The reliable, precision-controlled hydraulic
system ensures constant process control and high
availability.
- Thanks to the modular machine
concept, the CX series offers higher scope for
combination to meet individual manufacturing solutions.
- The MC 5 microprocessor control
ensures easy and reliable machine operation.
- The CX series is designed to allow
any automation solution to be easily integrated into the
manufacturing process.
