COLOMBO AGOSTINO 225.400 coil stamping and punching line

COLOMBO AGOSTINO 225.400 coil stamping and punching line was built in 2006 in Italy by Colombo Agostino S.p.A. Its extensive machining capabilities and high reliability make it an excellent choice for series production of components, such as washing machine parts or automotive parts. The production process is fully automatic, thanks to a high-speed feeding system. It unwinds the sheet metal from the coil towards the work station, which features precision tools operating at a maximum force of 400 tonnes. The monolithic design of the machine further ensures high durability and stress-free operation. The COLOMBO AGOSTINO coil-fed punching machine weighs 75000 kg.

The coil punching line is complete and consists of the following machines:
– 400 t eccentric press: COLOMBO AGOSTINO
– sheet metal decoiler: DEF CT 3/128
– coil lift table
– sheet metal straightener RA 3000/4-8/120 AR ZZ F.D. with roller conveyor
– guillotine shears
