New design for MACA RRM10 aluminium cap Redrawing Machine

MACA Engineering, of San Quirino Italy, a designer and manufacturer of machinery for the assembly and cutting of aluminium and plastics caps, has released a new version of their RRM10 Redrawing machine, where the two redrawing stations are now built on the same frame which reduces the footprint compared to the previous model by  2.5 metres in length.

The RRM10 is a continuous rotary motion redrawing machine with 10 punches suitable for lengthening and trimming long and extra long caps starting from either first draw (caps with heights up to 49mm) or second draw shell for caps that exceed 49mm. The redrawing is made by 10 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.

The new design has integrated the control panel of the machine under the loading channel which features a serpentine infeed that reduced the length of the equipment, but maintains the necessary quantity of caps required to feed the machine.

The machine has an output speed of 36,000 caps per hour.
