Several types of plastic were being used and there were mixed materials within the plastic-fiber optic cables and steel carrier.
Line Speed
The manufacturer required line speeds of up to 147 feet (45 meters) per minute.
Solution
Heat
A Model E4-10 Quad Ellipse Chamber was installed to anneal the multi-layer plastic extrudate.
Power Control
A Model 664F Phase Angle SCR Power Controller controlled the power to the Quad Ellipse Chamber.
Benefits
Improved Quality
By annealing the plastic extrudate on to the wire and cable, the manufacture was able to consistently produce cables that passed all transmission tests.
Power Control
By varying the power supplied to the Quad Ellipse Chamber with the SCR Power Controller, the manufacturer was able to anneal the different materials used to manufacture the cable with a single heat source.
Line Speed
Required line speeds of 147 feet (45 meters) per minute were maintained.
