Advantages：

Accurate deposit of rubber

Thanks to the “INCOM PROCESS®” system, the rubber is deposited directly on the base of the sole. With 5 different speed/volume steps, a precise distribution of the rubber is obtained with different properties in the variously involved areas.

Excellent control of compression pressure

The ability to produce outside toe-caps and counters proves the excellent control of the compression pressure and the exact positioning of the rubber carried out by the machine.

Notable capacity

Thanks to a large injection volume and to the variable screw loading speed, the rubber is well plasticized. The injectors operate at a lower than maximum capacity, guaranteeing the operation of the machine within its possibilities.

Heavy closing pressure on ring
(mould-holder structure)

The hydraulic closing pressure on the rings allows the use of great quantities of viscous rubber which could be needed to obtain tall, narrow profiles, e.g. for outside toe-caps or counters.

Dimensions of mould-holder

The large dimensions of the mould-holder make it possible to produce large-sized shoes, leaving a good closing surface of the mould around the cavity of the sole and thus guaranteeing improved distribution of heat for the vulcanization.

Short injection sequence

The injection-deposit sequence ensures rapid operation, outstanding yield and the possibility of a quick rotation, with consequent short cycle times.
