Description

APPLICATION

The automatic vulcanising press mod. PVA 350 CE Evolution has been studied and manufactured for the vulcanisation of silicone moulds fit for centrifugal casting.

PRODUCTIVITY

Once the vulcanisation temperature of 180°C has been reached, it is possible to produce one mould every 30/60 minutes, considering the diameter and the thickness of the rubber.

MAIN CHARACTERISTICS

• Tension: standard V380 three-phase 50Hz. On request all other tensions and frequencies:
• Dimensions of the heating platens mm. 350×350;
• Electric board separated from hydraulic power-pack;
• Electronic thermo-regulator controlled by microchip and equipped by a double-reading of the vulcanisation temperature:

1. a) the green display shows the programmed temperature (set-point)
2. b) the red display shows the real reached temperature into the machine;

• Electronic timer controlled by microchip for the vulcanisation cycle, maximum setting possibility of 99 hours and 59 minutes, equipped by automatic deactivation;
• Piston of diameter mm. 80 to grant an uniform and constant pressure and to obtain a perfect re-production of the models placed inside the rubber;
• Closure of the heating platens by simultaneous pressure of the two proper separated buttons, as per Directives CEE;
• Sliding protection of the heating area as per Directives CEE. It is mounted on bearings and equipped by safety end-travel; it permits the functioning of the machine, just when it is perfectly closed;
• General sectionalising switch, equipped by predisposition for latch, as per Directives CEE;
• Piston moving-down automatically at the end of the cycle when the vulcanisation time finish;
• Piston moving-down manually thanks to a lightening button, which shows the discharge;
• Hydraulic power-pack complete of electro-valve. The pressure is calibrated by an hydraulic control valve, which discharges automatically the exceeding pressure, created by the growth of the rubber into the frame.
