Vacuum Control System

The system is incorporated to the autoclave. It is used to create vacuum to evacuate air from laminated glass. This system is usually used to de-air bend laminated glass, especially bend armour glass before final bonding. This pre-vacuum process could be carried out either at room temperature outside autoclave or, under high temperature inside autoclave according to practical necessity. Glass is usually totally wrapped with special foil. There is fastener on foil. Vacuum hose is connected to fastener. When vacuum is turned on, air is evacuated from laminated glass within vacuum bag. Flat armor glass is also pre-vacuum with autoclave vacuum process. When vacuuming is accomplished, vacuum is turned off. Laminated glass is final bonded inside autoclave under high temperature, as usual. Vacuum pump and necessary supplies for this vacuum process are optional.

Air Compressor

It is used to generate necessary air pressure in air storage tank.
