Heater coils are generally the most popular heating element of any type of hot runner system due to their very low initial cost and widespread global availability. This makes them ideal for creating economical hot runner systems with easy to source spare parts. Generally speaking, heater coils are ideal for low cavitation hot runner systems producing simple cost sensitive parts and/or limited production runs or hot runner systems with extended nozzle lengths that benefit from having multiple zones (automotive). When used on longer nozzles they can be more difficult to install/remove as they can be tightly coiled around the nozzle so they don’t slide off like heater band sleeves.
Depending on the manufacturer, heater coils may also require larger cut-outs to accommodate their external design and sometimes larger terminal ends and clamping mechanisms. In addition, they generally have the shortest lifespan of any heater type and usually require replacement within 1-3 years so spare part and downtime costs can quickly eat up any upfront savings from an initially low system cost.
