Heating Tape

Mi-Plus belt heaters are suitable for temperatures up to 760 °C (1400 °F) and wattage densities of up to 23.25 W/cm2 (150 W/in2). Ceramic insulated belt heaters can meet the requirements for energy saving and operational efficiency. They are able to produce higher temperatures, which are essential for processing current resins. However, these standard variants and terminations of the Duraband heater do not represent the scope of our capabilities. Star Process and Controls’ technical staff, who have many years of experience in thermal processing and temperature control, can help you develop the right belt heater for your specific application. By far the most common culprit for the failure of belt heaters is environmental pollution.

If you have any questions or concerns about heaters, contact the team at Hi-Watt, Inc. for assistance. Plastics processing requires high operating temperatures and fast production rates. Omega has developed its ceramic belt heaters to meet these requirements. These heaters are in fact high-temperature electric furnaces that allow very efficient heat transfer through radiation, conduction and convection. The built-in insulation minimizes unwanted temperature changes throughout the run.

Belt heaters are designed to attach to an outer or inner cylindrical surface. Belt heaters often have higher wattage densities, which allows for rapid heating and high operating temperatures. They usually contain terminal kits that facilitate installation. Belt heaters are used for injection molding drums and nozzles, extrusion and molding presses, pipe heating, heat treatment and autoclaves, food industry and other applications. A thin layer of the thermally conductive “high” MI material is used to electrically insulate the element wire from the inner diameter of the heater cover. A thicker, “lower” thermally conductive layer supports the elemental wire by directing the heat inwards to the part to be heated.

The specially developed tightening clamp provides a complete and uniform closure for maximum heat transfer. A variety of terminal types and locations are possible to meet any installation Mica Band Heater Manufacturer need. Mica tape heaters consist of a resistive wire or an insulated tape between two mica plates. This assembly is protected by an aluminum sheet with high corrosion and heat resistance.

The belt heater, as shown in Figure 3, for the extruder has been specially manufactured. The specification of the belt heater used is 220 volts and 200 watts. The belt heaters have been adapted to the barrel with diameters of 35 mm and 40 mm. The heaters were connected to the solid state relay (Fig. 3), which is controlled by a PID controller (Fig. 3) for temperature control. The PID acts as an ON/OFF device that turns off the heating when the target heat is reached, and otherwise turns on the heating further. The heater is equipped with a clamping device that has a lid screw for easy and even adjustment of the heating in the barrel.

It also has exceptional dielectric strength, which contributes to its installation capabilities. They work well in areas where a lower maximum temperature is required. Our cast belt heaters are offered with cooling pipes for liquid cooling or with fins for air-cooled applications. Add the square footage of all the rooms you want to heat at the same time. Bayonet adapter connected to heater: Standard bayonet adapters are welded to a bracket and then attached to the heater over a hole with a diameter of 3/8 inches. Mica nozzle heaters have a small diameter and are used for low to medium temperatures up to 300°C.

Enthalpy is defined as the amount of heat required to change the temperature of the mass unit of the material from one temperature to another. Therefore, the amount of heat required to change the temperature of a material between the specified limits is the product of its mass and the change in enthalpy. Depending on the tool, the injection molding machine may not need to operate at full clamping pressure.

Tempco ceramic belt heaters have become extremely popular with OEMs as standard heaters for the drums of plastic injection molding machines, extruders and blow molding lines. If you are looking for industrial electric heaters, you need to make sure that you choose the right one. There are several options, including mica, ceramics, high wattage, and extruded aluminum heaters. Mica bands provide better thermal conductivity, with ceramic bands using radiant heat instead of conductive heat. High watt density strips offer newer plastic resins with higher watt temperatures, while aluminum strip heaters are durable and can withstand oil, plastic, and other materials. Ultimately, these are some of the most important factors to consider when trying to find industrial electric heaters.

Like many maintenance products used in the plastic injection molding industry, belt heaters are often not in the foreground until a problem occurs. Whether mold defects or machine downtime, only when a problem occurs, the belt heating becomes an important facet of machine production. A common case where this type of heating is useful is when an engineer needs to heat the surface of a pipe or pipe. Other applications could include the use of heating tapes for injection molding and heating tapes for extruders. The heater is mainly used in the plastic injection molding machine, the plastics processing industry, the head heating part of the hollow molding machine and the extrusion machine.
