Ceramic Band Heaters provide long life and use less wattage (because of insulation) in plastics extrusion and injection molding applications. These band heaters are constructed with a stainless steel shroud enclosing high quality ceramic knuckles through which run coiled high temperature nickel-chromium element wire.
Stainless Steel mica band heater was made of stainless steel sheet, mica sheet, resistance wire/ strip , stainless steel sheet standard thickness is 0.3mm to 0.5mm, and in the middle , resistance wire/ strip wrap around the mica sheet, and add 1-2 pieces mica sheet again each side for insulation. They can be made to be many different kinds of shape as your requirement.

They can be made to be many different kinds of shape as your requirement. It is the ideal solution for high watt densities and high operating temperature applications, especially for the plastics industry. Band heaters can be found in several types of dimensions, wattage, voltages and material. It is an inexpensive form of heating solution to external indirect heating.
Stainless steel tubular heater is cylindrical electrical heating elements with two head. Protected with a stainless steel sheath. Mostly double head heater is used for heating up solids such as injection presses heating plates or various tools, double head heater can also be used for heating up water of gases under certain conditions.The choice of technology will depend on technical specifications required and the application.When you don't know exactly which product you are looking for, we will recommend you the best solution for your needs.Tubular heaters are custom designed in a various shapes to as clientâ??s requirements for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases.
MAGMA cartridge heaters are suitable, appropriate devices for applying concentrated heat to solid metal components. Cartridge heater is somewhat similar to tubular heaters structurally but with higher watt densities, usually custom manufactured to size, sheath, leads, terminals, wattage and voltage as per application or requirement. Cartridge heaters are used in restricted working areas where localized heating is required for close thermal control. MAGMA manufactures wide range of cartridge heaters for different numerous applications like heating liquids (Water, Oil and Glues), Gases such as Air and Solids such as Metal Dies. MAGMA manufactures 2 types of Cartridge heaters: HIGH WATT DENSITY Swaged or High Watt Density Cartridge Heaters composed of resistance wire (NiCr) spirally wound on MgO core as per watt density decided. It is inserted in metallic tube selected as per requirement and space filled with high purity MgO powder. Then it is swaged to compact the loosely filled powder inside for achieving high dielectric strength up to the desired size, diameter and wattage is achieved. The heat generated by resistance wire is quickly dissipated or transferred to the outer sheath. It is machined to precise tolerances and straightness. Swaged or High Watt Density Cartridge Heaters are fitted into accurately reamed, parallel sided holes for useful life and fantastic performance. It can operate at higher temperature and vibration applications. STANDARD or LOW WATT DENSITY Low Watt Density Cartridge Heaters comprises of helical coil (NiCr resistance wire) passed from refractory core and inserted in metallic tube which is predecided by size, diameter and sheath. The remaining space in the tube is MgO powder filled but not compacted by machine. The end cap is then inserted on the bottom of the heater and insulated leads are installed.
Detailed description: Cartridge heater is cylindrical electrical heating elements. Protected with a stainless steel sheath, their watt density can reach 25 w/cm2 and their operating temperature can go up to 800¡ãc (1472¡ãf) Mostly cartridge heater is used for heating up solids such as injection presses heating plates or various tools, cartridge heater can also be used for heating up water of gases under certain conditions. Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc . Cartridge heaters are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries Various cartridge heater technologies are available. The choice of technology will depend on technical specifications required and the application. Unless you know exactly which product you are looking for, we will recommend you the best solution for your needs. 10*10*10cm3 per 10piece

Cartridge heater is one of the tubular heating elements. The heating part is a nickel-chromium heat-resistant alloy wire wound on a magnesium oxide core rod with excellent insulation and thermal conductivity. Between the heating wire and the outer sheath is high-purity magnesium oxide powder as an insulating material, and the air inside is compressed by the machine Into a cartridge heater. After the main body of the cartridge heater is completed, fixed accessories or threads can be installed according to customer needs. There are many types of fixed accessories or thread structures. Please contact our sales or technical personnel for the best solution. Advantages: Small diameter, can be 3-35mm; The length is not limited, it can be 20-2000mm; The power is high, which is 2-5 times the power of the normal electric heating tube, and it can achieve a surface area of 20 watts/square centimeter; even a surface area of 60 watts/square centimeter; It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life, no pollution, and low price. It also saves electricity, is safe to use, can be bent into various shapes, is light, and is easy to disassemble.
