MACA Engineering of San Quirino, Italy, has introduced a new version of its RRM10 redrawing machines for aluminium caps, available locally from HBM Packaging & Plastics Technologies .
In this new design, the two redrawing stations on the machine are now built on the same frame, reducing the footprint when compared to previous models by 2.5 metres in length.
In addition, the control panel of these redrawing machines has been integrated under the loading channel, which features a serpentine infeed that reduces the length of the equipment, but maintains the necessary quantity of caps required to feed the machine.
RRM10 machines are continuous rotary motion redrawing machines that feature ten punches suitable for lengthening and trimming long and extra long caps starting from either first draw for caps with heights up to 49mm, or second draw shell for caps exceeding 49mm.
Redrawing is made by ten dies that have a pneumatic drawing system that can be adjusted on each individual punch.
A cam with a constant descent profile ensures consistent control of the redraw (lengthening) process. The caps are discharged oriented, with separate ejection of the trim. Matrixes are made from sintered tool steels and are coated to ensure long life.
