Die andFormer <strong>Heaters</strong>Custom Cast and IFCOptimally heating extrusion dies canbe a challenge due to issues suchas high watt densities, hightemperatures, harsh environmentsand atypical configurations.Extrusion houses require continuousclose control of the die exittemperature to improve productivity,overall surface finish and productquality.Watlow’s custom cast and IFC(Interference Fit Construction)heaters can help solve thesechallenges while providingexceptional advantages in designflexibility, improved life andperformance. The heaters areavailable with integratedthermocouples and offer benefits likereduced lead times, minimal toolingand operating temperatures above350°C (660°F). The sealed heaterconstruction is less prone tocontamination problems and allowsthem to operate at highertemperatures with higher wattdensities.The custom cast and IFC heaterconstruction incorporates a heatedpart assembly that can be made withstainless steel, nickel or any othermetal that a customer requires.These heated parts are designedusing formed cable or tubularheaters, much like Watlow's classicaluminum cast-in assembly. Ratherthan being cast into the part,however, the IFC method employs apress-fit heater into a grooveproviding intimate contact whilereducing hot spots.Regardless of the heated parttechnique chosen, both afford theability to arrange the heater layoutfor the best temperature uniformity.In addition, the designs arestructurally suited to ac<strong>com</strong>modateholes and cutouts without<strong>com</strong>promising the heater's electricaland mechanical integrity.218Features and Benefits• Precisely molded tubularelements enhance heat transferpatterns.• Multiple termination options,shapes and sizes provide designand application flexibility.• Various sized cooling tubescast into heater body offer liquidcooling capability.• Multiple holes, tap holes andcutout options optimize designflexibility and expedite mounting.• Optional one piece constructionreduces assembly andmaintenance costs by offeringmounting holes for direct boltingto the mold.Application• Profile dies• Sheet extrusion dies• Blown film rings• Screen changers• Cross head dies• Platens
