Die Casting Features

AccuTherm Inc. can provide answers and products for your metal heating needs. If it is keeping casting alloys at the proper temperature, heating sucker tubes, crucibles, metal transfer tubes, nozzles or any other myriad of heating applications, AccuTherm’s trained application and product engineering team can provide the answer. AccuTherm can design a heating system to meet the most demanding needs in the industry. We will design and supply the right system for your application, from metal sheathed heaters, strip / open coil designs, thermocouples, to control panels.

Electric heat is easy to apply and can be located for spot heating a particularly vexing heat transfer problem. Since there is no open flame, electric heat is safe. There are no gas hoses or lines that can be inherently dangerous.

Electric heat is easy to control and monitor. With the many advances made in the solid state temperature control and sensing probes, exact and accurate control is possible. State of the art control systems are easily adapted to the process control monitoring now required to meet IS0 quality assurance needs.

Standard Features

Standard voltage ratings are available from 120V to 277V. Wattage ratings to 600 Watts.

Precision wound nickel / chromium resistance wire type “A” 80% nickel 20% chromium. Suitable for operating temperatures of 1180° C or 2150° F. Designed for the maximum wire size, helical coil pitch, and centering in magnesium oxide matrix. Resistance wire fusion welded to alloy terminal pins providing a 360 degree circumferential weld bead.

Highest grade magnesium oxide with optimum compaction providing maximum electrical resistant properties coupled with excellent heat transfer characteristics.

Above parts are encased in an Incoloy® 840 alloy tube. Tube is roll reduced to finished size and annealed for bending. Terminal ends of the element are over-sleeved to provide corrosion protection from the hot metal.

Element is assembled into a machined steel cup. Inside diameter of cup is machined to close tolerances sized to fit your nozzle barrel. Standard unit will fit a 1.00″ diameter nozzle. Custom made units can be supplied for .750″ minimum to 1.125″ maximum nozzle diameter. Element is sealed into cup using a 677 degree C or 1250 degree F heat transfer cement. Ends of cup are welded with end disks providing a compact rugged assembly.

A wide variety of terminal leads are available. Standard leads are MG1000 (450 Degree C) nickel clad copper conductors. Over sleeves of conduit or braided sleeving are available.

Units are designed and tested to meet CSA, UL, CE, and NEMA standards.

Also available with internal Type K thermocouple.

Units are made in the USA.

Standard unit delivery, 120V 500W for 1.00″ nozzle, with standard lead configuration, Stock to one week; contact factory for specials.
