as other precision parts industries, are
demanding more precise, faster output
and higher production rates than ever
before. What’s more, complex geometries
require absolute precision – especially in
terms of surface quality, contour accuracy,
weight stability and reproducibility. FANUC
was aware of this when the company
decided to develop a larger machine with
the same reliability as the previous six
models with clamping forces between
150 and 3000 kN. Now we have 4500 kN
clamping force, 920 mm x 920 mm tie bar
spacing, a clamping stroke of 900 mm,
1300 mm x 1300 mm platens and a mould
height of up to 1000 mm. The α-S450iA
shows its impressive productivity
potential: for lawn mowers, Polypropylene
covers measuring 330 x 570 mm are
produced in less than one minute cycle
time: shot weight 725m³. A FANUC Robot
M-20iA, mounted on the IMM’s fixed
platen, takes care of demoulding and
depositing the hoods. force - works with a FANUC Robot LR Mate
200iD/7. It takes four rectangular (length
approx. 8 mm) LSR electrical connector
seals from the four-cavity mould and
deposits them on a conveyor belt. The core
of the system is the D18mm LSR screw/
cylinder unit developed by FANUC. Here,
a Robot system called QSSR (Quick and
Simple Start-up of Robotization) has been
implemented.
For products that need to be tightly
protected against environmental
influences, FANUC presents its
proprietary liquid silicone processing cell.
The ROBOSHOT α-S50iA - 500kN clamping ROBONANO DEMONSTRATION
At a demonstration station, mould makers
can discuss real precision with FANUC
experts. ROBONANO is the company’s
solution in the sector of finishing quality
FANUC now offers a further development
in multi-component injection moulding: a
rotary table with one of the most reliable
servo drives on the market. A production
cell of ROBOSHOT α-S150iA + vertical type
2nd injection unit SI-20A is automated
with a FANUC Robot LR Mate - also via
QSSR. Useful during the cold season: the
FANUC Robot deposits two-colour ice
scrapers moulded in a special hard PC/ABS
blend combined with a soft TPE handle on
the conveyor belt. Visitors are invited to
take the product home.
optical surfaces. ROBONANO’s typical
applications are the finishing of tool
inserts for injection moulding machines
when form accuracy and surface finish
requirements are strict, for instance in
the production of high quality optical
components. ROBONANO features a
high positioning accuracy with the
programming command resolution of
0.1 nanometre (0.1nm is equal to 10-10
meters or 1 Angstrom, the unit of length
used to measure the size of molecules
and atoms) which is required to achieve
optical quality surface finish. You can meet
a perfect showcase of FANUC state of the
art technology. In Japan ROBONANO has
been contributing for about two decades
to the success of FANUC’s customers
serving information and communication
technology, automotive, medical and
other industries. A video shows this new
machine tool in its ability to produce
highly precise, repeatable and stable
optical quality surface finishing on high-
precision mould inserts.
