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. 

End Product

Measuring tape

Equipment

Ambrell 20kW 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. 

Materials

Steel Measuring Tape stock, 3/8" wide on a continuous feed

Temperature

Above 400°F

Frequency

75 kHz

Testing

The Ambrell 20kW output solid state induction power supply along with a unique 30" long multi turn helical coil was found to produce the following results. 

Benefits

• 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
