Stainless steel mica electric heating ring
Electric heating rings are classified into: ceramic electric heating rings, mica electric heating rings, cast copper electric heating rings, cast aluminum electric heating rings
The injection molding machine industry uses them most widely.
Ceramic electric heating ring
1. One type is made by threading alloy wire through small ceramic blocks and encasing them in a stainless steel shell.
2. Ceramic heaters are not made by the usual mica winding method but by threading wire through ceramic strips. Therefore, the power of this product is 0.5 to 1.5 times higher than ordinary ones. The heating element is made of imported round wire ceramic wound into a spring shape and threaded into ceramic strips. The outer cover is made of stainless steel, and the middle uses high-temperature insulation cotton (aluminum silicate fiber board) to prevent heat leakage. The ceramic strips are high-frequency ceramics with fast heat transfer, hardness, resistance to breakage, and resistance to deformation and aging at high temperatures.
3. Ceramic heaters are made by passing spiral resistance wires through specially designed high-temperature ceramic tiles, precisely extended to form a bendable structure, with a beautiful metal shell and ceramic fiber insulation layer. This forms an effective high-temperature (1000°C), high-power density, strip heater with flexible design for easy installation. II. Technical features: According to user requirements for wiring methods, voltage from 36V, 110V, 180V, 220V, 380V, maximum power load of 6.5W per square centimeter. Compared with traditional electric heaters, energy consumption can be reduced by 30%.
Mica electric heating ring
1. Stainless steel mica electric heating ring uses 0.3~0.5mm stainless steel plate as the shell, high-insulation and high-temperature resistant mica plate as the core, evenly wound with various standard specifications of nickel-chromium alloy resistance wire as the heating element, and processed into various required shapes by a forming machine.
2. According to user requirements for wiring methods, voltage from 110V, 180V, 220V, 380V, maximum power load of 3.5W per square centimeter. Adding insulation devices on the outer heat dissipation surface and sintering infrared on the inner heat dissipation surface can save 35% electricity. Stainless steel mica heaters come in ring and plate shapes.
3. Product features: simple processing, reliable operation, convenient use, rapid heating, high thermal efficiency, low power consumption, long service life, and no restrictions on model or size.
4. Product applications: widely used in plastic machinery, packaging printing, petrochemical, electronic equipment and other industries. II. Ordering instructions:
1) Users should provide product drawings or samples. If no drawings or samples are available, the product specifications, model, voltage, power, etc. must be provided.
2) The maximum power load of stainless steel mica electric heaters is between 1.5 and 3.5 watts per square centimeter.
Cast aluminum electric heating ring
Cast aluminum heaters use tubular electric heating elements as the heating body, bent into shape, then placed in a mold and cast with the best metal alloy material as the shell using centrifugal casting to form various shapes, including round, flat, right-angle, air-cooled, water-cooled, and other special shapes.
After precision machining, it can closely fit the heated object. The surface load of cast aluminum heaters can reach 2.5-4.5 W/cm², with a maximum working temperature between 150-450°C.
Metal cast heaters are high-efficiency heaters with uniform heat distribution. The best thermal conductivity metal alloy ensures uniform surface temperature, eliminating hot and cold spots. They have advantages such as long life, good insulation performance, strong mechanical properties, corrosion resistance, and magnetic resistance. Adding insulation devices on the outer heat dissipation surface and sintering infrared on the inner heat dissipation surface can save 35% electricity.
Cast copper electric heating ring
Cast copper heaters use tubular electric heating elements as the heating body, bent into shape, then placed in a mold and cast with the best copper metal alloy material as the shell using centrifugal casting to form various shapes, including round, flat, right-angle, air-cooled, water-cooled, and other special shapes.
After precision machining, it can closely fit the heated object. The surface load of cast copper heaters can reach 2.5-4.5 W/cm², with a maximum working temperature between 150-600°C.
