Charging engine overheating seems to be a recurring problem with all-electric machines, and proper drying will reduce this problem. Depending on the tool, the injection molding machine may not need to operate at full clamping pressure. Operators must mark enough tonnage to avoid unnecessary battery charging. Radiant heating relies on electromagnetic waves to radiate heat onto an object without the need for direct contact. While all electromagnetic waves “heat up”, the infrared band of the spectrum contains the most useful heating energy. Important factors in radiant heating are the distance between the object and the heat source and how well the object absorbs radiant energy.
Starflex MPI belt heaters have minimal expansion and offer tight drum adjustment to ensure optimal heat transfer over the entire operating temperature range. Starflex MPI belt heaters can operate at temperatures up to 600°F. The second most common cause of premature failure is poor contact between the machine running and the heater. Because mica, high wattage, and extruded aluminum strips are conductive heaters, a tight fit is crucial.
Be careful not to remove or detach the BOTTOM nut from the feed screw terminals. 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. By rubbing the granules together against each other and against the cylinder and screw, the extruder generates the cutting heat required for melting.
Calculations such as these explain the light load surge that the world market has experienced in recent years and for which there is no end in sight. Our cast belt heaters are offered with cooling pipes for liquid cooling or with fins for air-cooled applications. Other inner diameters and widths, both between these and larger than those listed, are available. The construction of units with an inner diameter of more than 11 1/2″ should be manufactured according to the following table.
For the plastics, foundry and rubber industries, this device is the most widely used electric heater. Tempco ceramic insulated belt heaters are specifically designed and engineered to meet the ever-increasing demand for energy savings and improve operational efficiency. Ceramic belt heaters are able to produce the highest temperatures, which are essential for the processing of today’s high-temperature resins.
Some of the special options you can consider are the double-wire metal mesh, the two-piece construction, and the expandable one-piece construction. Mixed, ceramic and aluminium belt heaters are available in all standard sizes and finishing versions. Configurations for all equipment in the plastics industry, including injection molding, blow molding, and extrusion. Backer Marathon ceramic belt heaters are a powerful alternative to conventional mica belt heaters.

Are you looking for a reliable partner in the industry to deliver the belt heaters you need at prices you love and with a quick response? Metal band heaters are used to heat the contents of a drum or bucket such as a 55-gallon plastic drum heater or a 5-gallon bucket heater. These heaters contain electric heating elements in a metal jacket. Before using such a barrel heater, you need to know what kind of drum or bucket the contents are in and at what temperature you can tolerate the contents.
