Milled Groove Tubular Heaters
WATROD milled groove heaters are precision-formed hot runner mold heaters customized to your hot runner mold application. Even tight radius bends of 0.250 inch maintaining tolerances of ±0.062 to ±0.002 inch are possible. This capability not only allows you freedom to design for the optimum uniform heating pattern for your plastics process, but also guarantees quick and easy installation of each hot runner mold heater.
A variety of sheath materials are available including Incoloy®, 304 stainless steel and 316 stainless steel; each offering unique advantages of long life in high temperature molds, rigidity to maintain shape during shipment and corrosion resistance.
