Heating bands are the ideal solution for the heating of tubes an cylinders. Mica band heaters, frequently used as nozzle heaters, are made with a plastic-tight stainless steel casing. Such mica heating bands are in many dimension available from stock. The Ceramic heating band type is suitable specially for applications with high watt density and therefore for higher temperatures. Ceramic band heaters, also known as ceramic ring heaters or cylindrical ceramic sectional heaters, are attached to the contact surface by means of a clamping mechanism. A preferred field of use for ceramic band heaters is the heating of plasticising cylinders, bushings and nozzles of injection moulding machines and screw barrels of extrusion machines. For thermal optimization and process control ceramic band heaters can also be offered with insulation jackets or air cooling.

Besides their own clamp-band designs Freek also manufactures original Rosemount clamp-bands that can be used as "Husky-replacement heaters" (see spare part cross-reference list). For example the two screw clamp band (FB) and the axial clamp band (FE). Freek has all the various industry standards for clamp-band nozzle heaters in Ø19,05 and Ø22,40 in their assortment, too. HotCoil minitubular heaters with clamp band are a highly demanded and very flexible clamping system, especially for heating larger nozzles and bushings with high power. The size-variable customizable clamp bands counteract the heating's thermal-related "lifting ambition" during heat-up and thus effectively prevent a possible critical overheating. For an even better protection all HotCoil heating elements can also be provided with an integrated thermocouple. As alternative to our standard clamping mechanism with welded clamping elements a space-saving lug clamping mechanism can be supplied.

Ceramic Insulated (Band) Heaters are predestined for high-temperature applications beyond 450 °C, for example for pipe heating in process heat technology, especially when gases are involved. Ceramic insulated sectional surface heating elements are also brought into action where a heat storage capacity is needed, as in hot plates the case. With the heating surface of ceramic flat heaters being composed by small-limbed ceramic elements with aligned holes in the centre for the resistance coils to be fed through, ceramic sectional heating mats are also applicable for bent or cylindric surfaces. Like Micanite insulated flat heating elements also Ceramic insulated elements can receive a metal sheath. The latter provides additional protection against mechanical load and allows for attaching connection boxes. Another advantage is the easy installation by means of mounting holes in the metal cladding.

The Freek heat transfer nozzle heater type especially addresses manufacturers and users who operated their hotrunner nozzles with cast-in heaters in the past and would like to stick to their engineering know-how without paying the high price of this former heater design. The standard material of our patent pending Freek heat transfer alternative is brass, with or without coating, basically with a slit. Characteristics of our HotMicroCoil nozzle heaters sheathed by a reflection tube are easy mounting and variable heat distribution. Because of its direct touch and toleranced fit, the heater allows a very good heat transmission to the nozzle. In all our HotMicroCoils with reflection tube the assembly of a thermocouple is possible and recommended for bigger diameters and power. Also most common nozzle heater solutions are HotMicrocoil heating elements with clamp bands with diverse locking mechanisms.

Preformed silicone heaters are useful for diamters as small as 12 mm and up to 100 mm. Rounded silicone heaters are not possible with self-adhesive foil. Spiral Wrap Pre-Formed Silicone Rubber Heaters are suitable for tubes and flexible pipes and hoses with Ø 6,35 mm (1/4"). Spiral formed flex heaters can be used up to Ø 12 mm (the length of the stretchable silicone spiral wrap heater is reduced accordingly). The thickness of our spiral-wrapped silicone strip heaters is 2,2 mm. Also our gas and pump line heaters, most frequently used in the semi-conductor process, are shaped and pre-formed according to the object geometry to be heated. They are designed to regulate temperatures in order to prevent condensation in the line. Current applications here are Semi Conductors, Vacuum Chambers, Wafer Chucks, Valves, Exhaust & Pump Systems.

Micanite is a kind of insulation paper which is impregnated with a heat resistant binder and afterwards pressed in several shifts under heat and high pressure to plates. This material is heat resistant up to 350 °C, as special construction (Phlogopit) up to 450 °C, and is used for the wire wound formers as well as for the encapsulating cover plates of mica surface heaters. Because of the typical "sandwich"-construction of Micanite Flat Heating Elements and their high watt density it is necessary to use a platen to press the mica heater onto the surface to be heated. Established on the market for round Flat Heating Elements are some standard dimensions (Ø 58 / Ø 65 / Ø 80 / Ø 100 / Ø 160 / Ø 260 mm). But normally Micanite Surface Heating Elements are constructed on customer's request. Mica heaters can be metal sheathed for higher mechanical stability. This makes the heater flexible, so that it is also possible to build a band heater.

Insufficient surface quality, long cooling times, uneven thickness tolerances or other quality problems often limit maximum production output. Promix melt blenders eliminate these limitations sustainably and lead to significant cost savings. Would you like to optimize your extrusion process? Improved melt homogeneity and a more uniform melt temperature create tighter thickness tolerances and better surface quality. And quite often, it can also increase production throughput. Promix offers you highly effective static mixers and melt blenders at low investment costs. They are supplied ready for installation, including heater bands and holes for pressure and temperature sensors. The melt blenders are usually installed downstream of the screen changer & gear pump, and upstream of the die. The very short installation length allows easy retrofitting in existing extrusion lines.
