Hot RunnerNozzle <strong>Heaters</strong>Metric K-RING ® andMini K-RINGWatlow’s K-RING ® and mini K-RINGheaters take nozzle heatingtechnology a step ahead of the<strong>com</strong>petition. Thanks to the innovativedesign, plastic molders no longerhave to <strong>com</strong>promise with sloppy fittolerances, uneven temperatureprofiles or short heater life.Featuring a machined brass castingconstruction, these heaters canhandle very high temperatures whileproviding maximum heat transfer.Watlow’s mini K-RING design is idealfor applications where space islimited such as hot runner moldswith multiple cavities. The heatingelement fits easily into the small areaand heats with precision andefficiency.The K-RING and mini K-RINGheaters feature highly flexibleunheated ends which give thecustomer the ability to form leads tothe wire channel. The unit alsocontains small lead adapters whichtake up less space in the machine.With a precision machined insidediameter, the K-RING andmini K-RING heaters fit perfectly—and do not require clamping bands.Precision fit, along with the excellentthermal conductivity of brass, allowthe K-RING and mini K-RING to giveyou an extremely even temperatureprofile.Performance Capabilities• Operating temperature to 650°C(1200°F)• Maximum watt density on insidediameter to 50 W/cm 2 (320 W/in 2 )• Maximum voltage to 240VÅ(ac)Features and Benefits• Brass casting constructionprotects heater from damage, aswell as maximizes transfer of heatto heated parts.• Precision machining of lengthand inside diameter givesaccurate fit tolerances.• Sealed construction of theK-RING and mini K-RINGeliminates contamination.• Stainless steel outer casingprotects the brass heater body,and acts as an insulator.• Distributed wattage allows heatto be precisely placed for an eventemperature profile.• Customized diameters areavailable to meet specificapplication needs.Applications• Sprue bushings in plastic moldingequipment• Plastic injection nozzles• Hot melt equipment120
