<strong>Heaters</strong>Thick FilmFor <strong>com</strong>plete information onthick film heaters referencepages 127 and 143.The field-proven benefits Watlow’sthick film heaters bring injectionmolders are now being realized byplastics molders for a variety ofpackaging applications. Watlow’sinnovative thick film technologyallows packaging processors toevenly apply precisely calibratedheat with pinpoint accuracy, attemperatures up to 500°C (925°F).Hot and cold spots are virtuallyeliminated, allowing for rapidmachinery start-up and cycle times,reduced scrap and more consistentpackage quality.Thick film heaters offer precisecontrol and the ability to customizethe temperature profile. Whether sealbar or die head, the circuitry allowsthe heater to vary thermal outputacross the entire surface, helping tocontrol and correct almost anytemperature uniformity issue causedby conventional units. Thick filmheaters also provide design flexibility.The heater shape can match anyform desired, allowing the heater toadapt to unique machine dimensionsand geometry.Whether flat surfaced or cylindrical,Watlow thick film heaters are ideal fora multitude of packaging heaterapplications. Thick film heaters havebeen used on the face of seal bars inform, fill and seal machines to makepouches. Customized thick filmheaters are also used to sealprotective foils or plastic membranesto containers after filling. Cartons canbe sealed utilizing a head or roller,heated with thick film, whichdescends and seals lidstock to thecontainer or product.Features and Benefits• Uniform thermal profile andability to pattern heater layoutresults in even temperature forimproved product quality;eliminates hot and cold spots.• Low thermal mass allowsquicker heat up and less thermallag between the heater and thepart.• Extremely low profile allows forpremium space to be kept at aminimum.• Moisture-resistant non-porousglass film constructioneliminates the need for softstarting, minimizes currentleakage and ultimately reducescost by eliminating special needof GFCI protection.Applications• Seal bars• Lidding• Form, fill and seal• Cartoning• Adhesive heating and dispensing• Die cutting380
