(Plastics Today) -- The focus of Fanuc at the recent IPF show in Japan was system approaches rather than all-new machine models. One such solution on display was application of its horizontal 15-tonne Roboshot S-2000i15B press in hoop molding of LED components. Lead frame feed from the machine side is controlled via a servomotor/ball screw/clamp mechanism.
According to Fanuc Senior Development Engineering Satoshi Takatsugi, use of a horizontal machine in this application brings several advantages. "Firstly, a horizontal machine is cheaper than a vertical press and generally delivery lead time is quicker. You can also use a horizontal machine for standard molding jobs that don't employ inserts and of course the horizontal machine boasts a much lower profile."
Fanuc has also applied its servomotor expertise to feed of the metal tape (lead frame), which is controlled in a closed loop manner via the machine controller. The machine on show at IPF was molding LED components from LCP in a 6.5-second cycle using an eight-cavity tool.
