OVERVIEW
• The vacuum is displayed on a thermocouple sensing, computer calibrated, digital
gauge located on the front panel.
• The substrate is exposed to this Vacuum Dwell for a time determined by a
precision digital timer which is adjustable from .1 seconds to 9990 hours.
• At the end of the Vacuum Dwell, a preheated silicone rubber diaphragm
descends onto the work-piece and drives the spring-mounted drawer
mechanism into intimate contact with the lower heater platen.
• The temperatures of both the upper and lower heat platens are controlled
independently by digital, proportional, Temperature Controllers.
• A positive pressure of up to 10 PSI is applied to the top of the diaphragm to
bring the combined differential to nearly 25 PSI.
• The Pressure Dwell is adjusted by a precision digital timer identical to that
employed by the Vacuum Dwell.
• Upon completion of a cycle, the drawer mechanism is retracted and the
product(s) removed for further processing.
• The entire process is governed by a microprocessor driven programmable
controller. Programming modifications are available from the factory.
