Fanuc Robomachine Deutschland exhibited three of its electric Roboshot injection moulding machines which are aimed at high-end applications and low energy consumption. To achieve this, the Roboshot machines are equipped with energy recovery control, torque dependent dosing control, PMC 2 and 3, as well as with the specific backflow monitor and with efficient AI mould protection.
With a Fanuc Roboshot S-2000i-100B (1000kN clamping force) PP closure caps for syringes were produced at the K show using a specific 48-cavity medical device mould. Parts are removed by a linear robot, which was specially developed for medical applications by company Hekuma, with a positioning accuracy of 0.01mm. With a shot weight of 32g PP, the Fanuc injection moulding machines achieves a cycle time of maximum 8.1s.
Close cooperation with Otto Männer has resulted in a solution for two-component applications in small and micro volumes. The Roboshot S-2000i-150B has been modified with an integrated rotary drive and a flexible attachment option. It has therefore been equipped with a so-called “Duo-Män” bolt-on unit as second injection system. The fully electric Duo-Män injection unit is mounted directly to the mould half of the nozzle side. Using the eight-cavity 2K mould provided by Schneider two-colour felt-tip pen caps are produced in PP (16.5g per component, 17s cycle) and deposited by a handling unit.
Filigree functional parts with many complex geometries, as produced in large quantities in the electric and electronic industries, require maximum precision when it comes to surface finish, contour accuracy, weight and reproducibility. Here, Fanuc can provide a complex mould for the manufacture of connectors. With a shot weight of 22g four functional components in PBT are produced simultaneously in a cycle time of 12s. Part removal is handled by a three-axes linear robot, equipped with servo drives and control, by systems partner Hi Tech Automation.
