The solvent-based adhesive must be reactivated after drying on .025 inch (.6 mm) thick, 42 inch (1067 mm) wide cold rolled steel doors.
Line Speed
Line speed of 35 feet (11 meters) per minute required.
Solution
Heat
Two Model 4765-16-48 High Density Pyropanel Arrays were used to heat the metal doors from both sides and reactivate the dried solvent-based adhesive prior to lamination.
Power Control
The High Density Pyropanel Arrays were controlled by a Phase Angle SCR Power Control System.
Benefits
Speed
The solvent-based adhesive was reactivated and the required line speed was maintained using the Model 4765 High Density Pyropanel Array.
Quality
The Pyropanel Array provided uniform heating of the solvent-based adhesive for a consistently high-quality laminate.
System Integration
The SCR Power Control System automatically regulated the Pyropanel Array according to process conditions, keeping energy consumption to the minimum required.
