Induction Curing Measuring Tape Paint

Objective To heat measuring tape stock at a maximum rate of 600 feet per minute to cure the applied paint. The heating coil is to accommodate the 3/8″ wide stock within the customer’s current framework. Curing must occur above 400°F at the rate specified.
Material Steel Measuring Tape stock, 3/8″ wide on a continuous feed.
Temperature Above 400°F
Frequency 75 kHz
Equipment Power of 45kW output solid state induction power supply with remote heat station housing eight (8) 0.33 μF capacitors totaling 0.66 μF, along with a 30″ multi turn helical coil designed specifically for this application.
Process The UIHM 20kW output solid state induction power supply along with a unique 30″ long multi turn helical coil was found to produce the following results.
Results • A temperature of 500°F was achieved, at the necessary rate, using the unique 30″ multi-turn helical coil which surpasses the customer’s requirement of 400°F.
• The helical coil was designed to integrate with the customer’s present framework to eliminate any re-fixturing.
• The helical coil allows for the tape to travel internally with absolutely no contact thus maximizing surface quality.
