Electromagnetic induction heating technology can be widely applied in plastic machinery (such as blow molding machines, filament winding machines, injection molding machines, granulating machines, vulcanizing machines), food machinery, oil heating and conveying, chemical machinery, and other heating industries. Electromagnetic induction heating equipment, with its simple operation, ease of use, fast heating speed, high thermal efficiency, and significant energy-saving effects (reducing electricity consumption by 50%~80%), is gradually becoming the terminator of traditional heating equipment.
With your care and support, and our unwavering efforts, Runzhi can look forward to a future of prosperity together with you.
2. Rise in Workshop Environment Temperature: Due to significant heat loss, the surrounding environment temperature increases, especially during summer, which has a considerable impact on production. The on-site working temperature can exceed 45°C, forcing some companies to use air conditioning to lower the temperature, leading to secondary energy waste. 3. Short Lifespan and High Maintenance of Traditional Heating Coils: As they use resistive wire for heating, the heating temperature can reach several hundred degrees for extended periods, causing the resistive wire to easily burn out due to high-temperature aging. The lifespan of commonly used electric heating coils is not long, resulting in relatively high maintenance workloads. 4. Advantages and Characteristics of Electromagnetic Heating Systems: 1. Substantial Energy Savings: By adding an insulating layer between the high-frequency heating coil and the barrel, most of the barrel's internal heat is utilized, with only a small amount radiating into the air. The barrel's surface temperature is typically between 50-80°C, with rigorous testing showing energy savings of 30%-80%, particularly evident in high-power injection molding machines. 2.显著降低车间温度: As analyzed above, using a high-frequency heating system not only improves equipment energy efficiency but also the overall workshop temperature, creating a more comfortable working environment for employees. 3. Rapid Heating and Accurate Temperature Control: Traditional resistive wire heating is slow, with the plastic temperature at the barrel's center significantly differing from the surface temperature. In contrast, the high-frequency heating system heats the metal barrel itself, with heat generated by the entire barrel metal. Temperature control is real-time and accurate, ensuring consistent barrel internal and external temperatures, improving product quality and efficiency. 4. Long-Term Operation in Harsh Environments: Traditional resistive wire heating in plastic molding machines is susceptible to reduced lifespan in environments like oil contamination, poor metal heat conduction, and leaking plastic. Since the high-frequency heating system does not generate heat itself, it doesn't carbonize oil or plastic particles on its surface, preventing issues like leakage and short circuits. 5. High Heating Power: Traditional resistive wire heating can cause significant damage to the wire itself at high powers, with the metal wire volatilizing and aging rapidly at high temperatures, necessitating frequent replacements. In contrast, the high-frequency induction heating system only heats the metal barrel internally, has minimal electrical losses, and does not affect the system's lifespan even at high power. It can also adjust the power output as needed.
