Clamping Options
Strap Clamping
Strap clamping is used to secure the heater to the extruder barrel with 3/4″ or 1-1/4″ wide low expansion stainless steel clamping straps with 1/4″-20 socket head cap screws and barrel nuts.
Bolt Clamp
Strap clamping is used to secure the heater to the barrel by bolts clamping the two halves together around the barrel. A variety of bolt clamping designs and hardware is available.
Additional Options
125 RMS Standard
RMS Surface Finish as defined in ASME B46.1 — RMS is the root mean square of the profile height deviations from the mean line, recorded within the evaluation length. The standard surface finish for the machined surface of Tempco cast-in heaters is 125 RMS. Consult Tempco if a different surface finish is required.
Special Features
Electroless Nickel-Plated — A plating technique (without using an electric current) used to deposit a coating of nickel on a substrate to prevent corrosion, wear and also as a protective coating.
Teflon Coating — Teflon is non-reactive so it is often used in containers and pipework for reactive and corrosive chemicals.
Hard coat anodizing — Anodizing increases resistance to corrosion and wear.
Magnaplate — Strong wear and corrosion resistance non-stick coating that withstands high temperatures.
