Thick Film Heater Apparatus

US Patent:
7241131, Jul 10, 2007
Filed:
Jun 19, 2000
Appl. No.:
09/596549
Inventors:
Andrew Booth - Williston VT, US
Harold Warren - Sugar Grove NC, US
Wink Winkelmann - Boonb NC, US
Edward Jenko - Essey Junction VT, US
Jim Pilavdzic - Milton VT, US
Assignee:
Husky Injection Molding Systems Ltd.
International Classification:
B29C 45/74, H05B 3/16
US Classification:
425549, 425186, 425192 R, 425547, 425DIG 13, 219543, 338309, 392480
Abstract:
A thick-film electric heater having thick-film layers applied directly on a thermally conductive non-flat substrate. Preferably, the substrate is cylindrically shaped. A dielectric layer is silk-screened on the substrate surface. A resistive layer is silk-screened on the dielectric layer to form a circuit for the generation of heat. The resistive layer has at least one resistive trace in a pattern that is discontinuous circumferentially. At least a pair of silk-screened contact pads are applied in electrical communication with the resistive layer for electrical connection to a power source. An insulation layer is applied over the resistive layer.
