The cast aluminum heater is made of metal tube as a foreigner and is filled with high-resistance electrothermal alloy wire for heating. It is filled and compacted around the heating wire. It has excellent insulation performance and uses high-purity magnesium oxide with high thermal conductivity as filler. The cast aluminum heating tube has the characteristics of large intrinsic power, high thermal efficiency and fast heat dissipation. Commonly used in plastic packaging, small mold heating, analytical instruments, cigarette industry, footwear industry, semiconductor eutectic welding, die-casting input channel heating and non-watering injection, refrigeration effects of various gas expansion and other heating. Although there are many advantages, there are also disadvantages.
The defect of the cast aluminum heater is dry burning, so the temperature will only rise and the constant temperature effect cannot be achieved, and the internal heating wire is simply burned. When you encounter metal or liquid, it will leak electricity, causing the incident to occur. For example, an electric kettle. Inside the hot water, there is a small cast aluminum heating pipe, which contacts the water, energizes the work, releases the heat energy, and gradually disperses the water. After waiting for the time, the water will gradually heat up and reach the temperature request we need. If there is no power-off operation at this time, the cast aluminum heating plate will continue to work continuously, and the water will gradually transpire. When the time is long, the water will be completely transpiration, and then it will self-dry, so it will be impossible to estimate. the result of.
However, these cast aluminum heater are usually equipped with a device for controlling the appearance. This can be more convenient, safe, and environmentally friendly. Many people always like to leave when they use electric heaters. No one is guarding them. It is extremely simple and causes many disasters. This kind of thing is not uncommon. If equipped with these intelligent control surfaces, it will be much more convenient and much safer. Originally, this principle is very simple, just like we set an extra temperature for the cast aluminum heating tube. The cast aluminum heater is converted into thermal energy through electric energy. When it reaches this temperature, the control surface will take the initiative to operate, and the cast aluminum heating tube is powered off. Or constant temperature to ensure safety
The cast aluminum heater is a tubular electric heating element which is a heating element. It is forged by an excellent aluminum alloy material. Its operating temperature is usually between normal temperature and 350 degrees. It can be widely used in plastic machinery, die and cable machinery. Chemical, rubber, petroleum and other equipment. The main processes of production are:
1. Accurate drawings. Before forging each item, we will determine the accurate drawings with our customers. We also have professional customer service and technical personnel to produce detailed drawings for our customers to ensure that the cast aluminum heating tubes can satisfy the customer's request.
2. Open the mold and make the tube. The mold is opened according to the professional drawings, and at the same time, the manufacturing tube is manufactured. The electric heating element is made of excellent alloy wire, high temperature resistant magnesium oxide powder and more than 50 ohms. A professional manufacturing team processes the metal-filled materials according to the drawings.
3. Casting. The cast heater is lubricated outside, no sand hole, no forging defects, the electric heating element is directly forged into one, the service life can reach 3-5 years, and the export high-precision new product can be spared a set of electric heating elements, and the service life can reach 7-8. year.
4. Enter the inspection. Through strict factory inspections, the quality of the products can be ensured.
