Automatic Pneumatic Vulcanizing Press for rubber belts using water or air pressing system
Low pressure pneumatic vulcanizing presses, IVB-JP-F, are similar to the high-pressure IVB-IP-F, the difference between the two lies in the pressing system.
The high-pressure pressing is performed point-like by hydraulic cylinders and the low pressure vulcanizations are done using a pneumatic / hydraulic air bag in which the pressure is distributed uniformly.
1. Compressed air cooling system includes a compressor with high flow and low weight. Duration of the forced air cooling is approx. 2 hours and it may vary depending on the type of the compressor and the outdoor temperature.
2. Water cooling system. In this case the heating plates are provided with coil type cooling pipes that will connect to a local cold water network. In the event that the area doesn’t have a water cooled network accessible, the system is equipped with a pump and recirculating tank.
Duration of the forced cooling using water is approx. 30 minutes, and it differs depending on the outside temperature. Cooling systems have the advantage that they significantly reduce vulcanization, resulting in increased availability of the conveyor belt. Cooling of the natural environment can be up to 10 hours in summertime.
Automatic pressure control option is available only with high-pressure hydraulic pump. This option reduces the time needed for the pressure to rise and automatically maintains a constant pressure in the curing process.
The monitoring system is used to record and monitor the curing parameters, namely the temperature of the heating plates and pressure. The system allows maintenance engineers for checking the following: compliance with process parameters, the actual start and completion of vulcanization, the duration and condition of the installation.
Downloading process parameters is done via the USB interface mounted on the front of the switchboard. Download frequency data varies between a few weeks to several months depending on the storage period set. The measured values are displayed in the program installed on your PC in graphical or tabular form.
