2. Workshop Temperature Rise: Due to significant heat loss, the surrounding environment becomes warmer, especially during summer, which has a substantial impact on production. The working temperature on-site can exceed 45°C, leading some companies to use air conditioning to lower temperatures, which in turn causes secondary energy waste. 3. Short lifespan and high maintenance of traditional heating coils: As they use resistance wire for heating, the temperature can reach several hundred degrees for extended periods, causing the resistance wire to easily burn out due to high-temperature aging. The lifespan of commonly used electric heating coils is not long, resulting in relatively large maintenance workloads. 4. High workshop temperatures lead to increased machine oil temperatures, significantly shortening the lifespan of seals and oil pumps, and causing oil leakage and pressure instability. Advantages and Features of Electromagnetic Heating Systems: 1. Substantial Energy Savings: By adding an insulating layer between the high-frequency heating inductor and the barrel, most of the heat generated within the barrel is utilized, with only a minimal amount radiating into the air. The barrel surface temperature is typically between 50-80°C, and rigorous testing shows energy savings of 30%-80%, with even more significant savings for high-power injection molding machines. 2. Significant Temperature Reduction in the Workshop: Not only does the high-frequency heating system improve energy efficiency, but it also enhances the overall workshop temperature, allowing employees to work in a more comfortable environment. 3. Rapid Heating and Accurate Temperature Control: Traditional resistance wire heating involves the wire generating high temperatures first, with the heat then slowly conducted to the barrel center, resulting in slow heating and a significant temperature difference between the barrel center and surface. In contrast, the high-frequency heating system causes the barrel to heat itself, with the heat generated by the entire barrel metal, ensuring real-time accurate temperature control and consistent temperatures inside and outside the barrel, significantly improving product quality and production efficiency. 4. Long-term Operation in Harsh Environments: Traditional resistance wire heating in the barrel is prone to reduced lifespan in environments like oil stains on the heating position, poor metal heat conduction in the barrel, and leakage. Since the high-frequency heating system does not generate heat itself, it does not carbonize oil stains or plastic particles on its surface, thus avoiding electrical leakage and short-circuit faults. 5. High Heating Power: Traditional resistance wire heating in the barrel can cause significant damage to the wire at high powers, with the metal quickly evaporating and aging, necessitating frequent replacements. The high-frequency induction heating system, however, only heats the metal inside the barrel, resulting in minimal electrical losses and no impact on the system's lifespan when operating at high power. It also allows for power adjustment based on specific needs.
