Automation with FANUC injection moulding machine and robot

During Swissplastics, FANUC will show how a 100-ton ROBOSHOT all-electric injection moulding machine works hand in hand with a six-axis FANUC LR Mate robot at booth B 1033 in hall 01.

During Swissplastics FANUC will show on booth B 1033 in hall 01, a production cell incorporating an all-electric 100 tons ROBOSHOT, which will produce technical parts in engineering grade plastics under “Variotherm” mould process. The system literally works hand-in-hand with a six-axis FANUC LR Mate robot for parts assembly and handling. ROBOSHOT machines fulfil strict user requirements aimed at low energy consumption and flawless injection moulding quality, combined with stable repeatability and maximum process security.  

Using the example of a compact production cell, FANUC demonstrates a high-tech / high-batch production concept demanding clean machines, cleanroom environments and robotized activities, promoted today by e.g. the medical device and technical branches. Robotec PLASTICMATE and FANUC ROBOSHOT α-S100iA interact in a compact and flexible production cell. Demonstration of the integrated “Variotherm” function: in-cycle mould temperature changes improve the mechanical properties of the parts. The controlled cavity surface temperature does not only maintain low viscosity up to complete and immaculate mould filling it also allows special surface effects. Parts removal is carried out by a six-axis FANUC LR Mate robot combined with a linear axis. Subsequently, the top and bottom parts are deposited in a trace buffer before they are assembled automatically and deposited for the visitors in an output station. 

Not present at Swissplastics, but now also available in Switzerland is FANUC's all-electric 450-ton injection molding machine

The fully electric FANUC ROBOSHOT α-S450iA precision injection moulding machine with 4500 kN clamping force started its European market success last year from Fakuma. Higher cavity numbers and bigger moulds require larger platen sizes and tie bar distances which demand a larger/stronger machine with higher clamping forces. Beyond automotive, the medical / pharmaceutical device markets and other precision parts branches want more precise and fast output. “That is how the market works”, agrees Wolfgang Haak, FANUC’s Product Manager ETS Europe Roboshot, “and FANUC was aware of that – deciding to develop a bigger machine based on the same performance and reliability as the other six models between 150 and 3000 kN clamping force. Now we have 4500kN clamping force, a tie bar distance of 920 mm by 920 mm, a clamping stroke of 900 mm, a 1300 mm by 1300 mm platen size and a maximum die height of 1000 mm. Four different screw sizes for the two basic injection units achieve high flexibility.” The α-S450iA demonstrates the machine’s productivity potential: connection pieces for infusion components are produced using a 32-cavity medical device mould. Complex geometries, as produced in very large quantities in the medical device and pharmaceutical industries, require maximum precision – particularly pertaining to surface quality, contour accuracy, weight stability and reproducibility. State-of-the-art CNC technology in the ROBOSHOT provides a unique electric moulding solution. The machine is equipped with efficient energy recovery control function, reliable torque plasticise control – Precise Metering Control (PMC) 2&3 – as well as backflow monitor and highly efficient AI mould / ejector protection. The results are high-end process performance and product quality.
