Problem

Problem
Small Area
The medical implants being heated had a very small surface area.
One Piece Processing
Existing curing method processed one implant per cycle.
Poor Quality
The epoxy coating “skinned over” if exposed to too much heat.
Slow Speed
Existing curing methods required too much time because the heat had to remain at very low temperatures due to the narrow cure window.
Increasing Production Requirements
The manufacturer needed to increase production output to satisfy demand for the implants.
Solution
Heat
A Model 5194 Infrared Line Heater was used to apply heat to cure the epoxy coating.
Curing from Inside Out
The focused infrared provided by the Infrared Line Heater penetrated the epoxy, curing it from the inside out.
Power Control
The Infrared Line Heater was controlled with a Model 664F Phase Angle SCR Power Controller equipped with closed loop feedback on voltage.
Benefits
Increased Speed and Output
The Infrared Line Heater applied a higher temperature to the epoxy, enabling the manufacturer to process ten parts at a time.
Improved Quality
Curing the epoxy from the inside out prevented the quality problems associated with the epoxy “skinning over”.
Repeatable Results
The power control and closed feedback system made curing results consistent and repeatable.
