From OPTEK we provide a Differential Pressure Laminator
OPTEK DPL-24

DPL-24	unrivaled level of vacuum coupled with the use of positive pressure   maximum evacuation as no pressure is applied to the lamination sandwich during the Vacuum Dwell   true Isostatic lamination thanks to a flexible diaphragm which compresses and encapsulates the product during the Pressure Dwell

The DPL-24 Differential Pressure Laminator has been designed to give the operator a flexible method for laminating sheet supported emulsions onto a variety of substrates. 

These substrates, pre-laminated either manually or wigh the assistance of currently available dispensing equipment, are placed on a slide mounted platen and positioned in the chamber. 

Substrates varying in thickness and geometry may be intermixed to increase thoroughput. 

The fully automated cycle is activated from the front panel and controlled by a microprocessor driven Programmable Controller. 

Utilizing a high vacuum (42 CFM), rotary vane pump, a vacuum end point below 2 Torr is achieved. 

This vacuum is displayed on a computer calibrated digital gauge located n the front panel. 

The substrate is exposed to this Vacuum Dwell for a time determined by a precision digital timer that is adjustable from 0.1 seconds to infinity. 

Following this period a preheated silicone rubber diaphragm descends onto the workpiece. This action closes the small gap below the spring-mounted platen assembly and provides direct thermal contact with the lower heat platen. 

The temperatures of both the upper and lower Heated Platens are controlled independently by microprocessor based Temperature Controllers. 

Unlike conventional Vacuum Laminators, the DPL-24 permits the addition of positive pressure above the diaphragm, increasing the effective lamination pressure dramatically. 

The Pressure Dwell period is adjusted with a timer identical to that employed in the Vacuum Dwell. 

Upon completion of a cycle, the drawer mechanism is retracted and the products removed for further processing.
