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.
The accumulation of dirt is another factor that forces the contractions to come together unevenly. Ninety degrees compared to the gravity of the closing effect result in a slight sagging of the moving tool side after the bushings or linear bearings that hold them are worn out to a certain extent. DGM high-performance nozzle belt heaters are Mica Band Heater Manufacturer used in injection molding and extrusion machines, as well as for other equipment with superior polymer processing. Heaters with high watt densities offer a high operating temperature, resulting in high productivity. Even though this type of heating may not be able to handle higher temperatures, it is not as expensive as other options.
Most closing nozzles have the disadvantage that they restrict the material flow and cause unwanted stagnation points. For this reason, they should not be used with heat-sensitive materials such as PVC. There is very little shear heating in the transfer pipes and heaters are needed to keep the plastic melted. This thermograph shows excellent use of insulation in a transfer pipe to reduce energy consumption. Individual steel drums can be heated by heating the mains frequency by induction heating. The magnetic field generated by the induction heater creates eddy currents in the drum wall, causing the steel to heat the contents.
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.
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.
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.
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.
