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.

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. www.fanuc.eu/uk/en 27
