The tubular plastic stock was cut with a knife that produced chipped and ragged cut edges.
Stock Differences
The tubular plastic stock was made in a variety of sizes and colors.
Solution
Heat
Two Model 4185-05 Infrared Strip Heaters were enclosed on opposing sides of a reflector unit installed on the production conveyor to heat the plastic stock before it was cut.
Power Control
A Model 609 Phase Angle SCR Power Controller with a remote-mountable one-turn potentiometer controlled the power to the Infrared Strip Heaters.
Benefits
Improved Quality
By applying precisely controlled heat with the Model 4185 Infrared Strip Heaters just before the plastic was cut, the manufacturer softened the plastic, resulting in a clean, smooth cut.
Adjustable Heat
The potentiometer adjusted the Infrared Strip Heaters for the varying sizes and colors of plastic.
