The existing method of drying the water-based ink with a convection heater did not consistently produce quality markings on the parts.
Excessive Scrap
An excessive number of parts were being scrapped due to the inconsistent quality.
Slow Line Speed
The existing line speed of 7 feet (2 meters) was not fast enough to meet production output requirements.
Unfocused Heat
The surrounding area was being heated with the existing convection heater, resulting in employee discomfort.
Solution
Heat
A Model 4185-10 Infrared Strip Heater provided heat to dry the water-based ink.
Power Control
A Model 5620 Phase Angle SCR Power Controller controlled the power to the Infrared Strip Heater.
Instant On/Off
The Infrared Strip Heater responded instantly to changes in line speed.
Benefits
Improved Quality
Drying the water-based ink with the Infrared Strip Heater
Consistently produced quality markings on the parts.
Reduced Scrap
The need to scrap parts due to poor quality on the inked markings was virtually eliminated.
Faster Line Speed
Using the Infrared Strip Heater allowed the manufacturer to increase line speed to 20-25 feet (6-7.6 meters) per minute.
Focused Heat
The Infrared Strip Heater focused heat on the parts only, increasing employee comfort and eliminated the need to provide additional room air conditioning.
