Casted-In-Band Heaters
MATRUSREEs CAST-IN band heaters have proven to be the most effective method for heating and cooling the barrels of plastics processing extruders. They are extremely efficient, providing thousands of hours of dependable, trouble free service. Specifically for close contact heating enabling precise heat conduction. Cast Aluminum heaters are machined to fine limits and complex patterns are achieved. They can be produced to your specifications or drawings, alternatively, against your sample. MATRUSREE offers CAST-IN band heaters with liquid and/or air-cooling functions. Liquid cooling incorporates tubing formed to a specific shape and casted as part of the heater assembly creating a passage for processing water or heat transfer solutions to dissipate the heat. Air-cooling incorporates numerous fins casted to the O.D. surface of the band.
Construction:
The heat sources for MATRUSREEs CAST-IN heaters are tubular heating elements. They can be formed into endless configurations to Accommodate any practical CAST-IN heater shape or formed and casted in and around machine component parts such as fluid transfer pipes, valves, reducers, tees, elbows, and other special assemblies requiring localized heat. The sheath material is Stainless Steel and heater diameter will vary depending on CAST-IN heater design. Aluminum is the predominant alloy used for CAST-IN heaters. Brass is used when the operating temperature required exceeds those of Aluminum. Also recommended for heated platens on molding presses as Bronze can withstand more pounds per square inch of pressure.
Features:
Habitually, liquid cooled Cast-In Heaters have been the more frequently employed method of controlling the melt temperature of extrusion barrels. There is no doubt about the effectiveness and speed of liquid cooled castings in removing heat from the extrusion process. However, there are some drawbacks that primarily relate to maintenance-associated issues. Air Cooled Cast-In Heaters are virtually maintenance free and therefore, when properly installed and applied, have the capability to far outlast their liquid cooled counterparts. Since cooling tubes are not used, the possibility of breakage, cracking or becoming clogged with brine or mineral deposits is not a concern.
Additionally, Air Cooled Cast-In Heaters do not require an expensive cooling tower or heat exchange system, extensive plumbing systems and labor for installation. These factors along with the benefit of being maintenance free make MATRUSREEs Air Cooled Cast-In Heaters an economical and practical source for your extrusion heating and cooling application.
In certain instances where air-cooling alone will not sufficiently cool the process, liquid cooling tubes can be cast into the heater as well to maximize BTU removal

MATRUSREEs strip heaters are constructed of specially selected high quality materials, beginning with the high temperature alloy resistance wire uniformly coiled and spaced over the width of the heated length of the strip heater. This controlled coil process and replacement assures uniform heat distribution over the entire active surface of the heater. Special care is taken to secure the stud-type terminal to the high-temperature alloy resistance contact.The coiled resistance wire is embedded in a special refractory Material that possesses excellent heat transfer characteristics and superior insulation properties. The entire heater assembly is encased in either stainless or chrome steel sheath and is compressed under high pressure. The completed assembly is heated under controlled conditions to bake and semi vitrify the refractory for a rigid, vibration resistant, heavy-duty heating unit.

MATRUSREES cartridge heaters are most frequently used for heating metal parts by insertion into drilled holes. For easy installation, the heaters are made slightly undersize relative to their nominal diameters i.e., the inner diameter of the hole can be between 0.15mm and 0.30mm larger than the cartridge diameter. The lesser the clearance between the heater and the bore diameter, the longer will be its life .

Application:
Finned tubular heating elements are of the type where the surface area is enlarged by a strip in order to heat gases. At high power the surface temperature is small and the heating element is short.MATRUSREEs Finned Tubular Heaters are manufactured with the same rugged construction as the standard Tubular Heaters except a MILD STEEL ELECTROPLATED or a corrugated 304 STAINLESS STEEL FIN is helically wound on Heater Tube diameter (304 stainless steel) element. To insure a permanent bond, each end of the fin is fully brazed to the Heater sheath, for optimum heat dissipation and efficiency, as Brazed fins transfer heat at about double the efficiency of unbrazed designs. These heaters are ideal for heating air and select gases in forced and natural convection applications.

Construction:
The cutaway view of a typical MATRUSREEs tubular Heating element shows its basic construction. A coil of the highest-grade resistance Wire (80% nickel, 20% chromium) is precisely centered in a heavy gauge metal tube while the tube is filled with granular magnesium oxide powder. Terminal pins are Screwed / welded or silver soldered to the resistance coil at each end to provide an unheated length near the terminals and to secure the coil in the magnesium oxide. Through Swaging, the diameter of this assembly is reduced and the magnesium oxide compacted, insuring rapid heat transfer from the coil to the sheath, as well as high dielectric strength. After compaction, the element is processed in one of three Ways:
For applications requiring both terminations at the same end, either a U-bent or a two-pass element may be used. Two-pass elements, as shown in the cutaway view, have a U-bent coil inside the sheath and two leads or terminals at one end. Welding or silver soldering seals the opposite end. These elements are available in straight lengths, either finned or unfinned. They can be permanently mounted with a variety of factory-furnished mounting methods. By contrast, standard elements in straight lengths must have a flexible electrical connection at one end to allow for thermal expansion.

Applications:
Inserted in machined holes to heat dies and platens.Multi zone heating.High temperature furnaces.Simulated fuel elements for nuclear reactors.Pressurizer heaters.Dry out heaters in large generators.
MATRUSREE Ceramic band heaters are medium-to-high temperature heaters that have 650C as a maximum working temperature. These durable heaters have in-built ceramic fiber jackets that make them energy efficient. Ceramic band heaters are available with different terminal styles, are fully flexible, and can accommodate holes and cut-outs.
Construction:
Ceramic Band Heaters design consist of a helically wound resistance coil made from 80/20 Nichrome wire, evenly stretched and precisely strung through a specially designed Ceramic insulating bricks forming a flexible heating mat. The ceramic heating mat along with 1/4" thick ceramic fiber insulation is placed in a stainless steel housing made with serrated edges providing maximum flexibility for easy installation. This construction prevents heat loss and reduces electrical consumption by 15%. Because of low thermal conductivity of CFI the external surface temperature of the Ceramic Band is around 200C while running the inside surface temperature at 650C.Heat is transferred from a ceramic heater to the surface of an application through conduction and radiation. This is why a tight grip on the cylinder is not as critical as in other types of heaters. Moreover, over tightening should be avoided, since the pressure on the insulation mat reduces its insulating efficiency. Using different combinations of ceramic tiles, which are available only in specific lengths, makes ceramic band heaters. Consequently, the width of a ceramic band heater falls within a certain incremental range.Ceramic Band Heaters can be manufactured with different clamping mechanisms, terminations styles, holes and cut-outs.
