Electromagnetic induction heating technology can be widely applied in plastic machinery (such as blowing film machines, drawing machines, injection molding machines, granulating machines, and vulcanizing machines), food machinery, oil heating and conveying, chemical equipment, 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 effect (reducing electricity consumption by 50% to 80%), is gradually becoming the terminator of traditional heating equipment.

With your care and support, and our relentless efforts, Runzi can look forward to a future of brilliance together with you.

2. Workshop Temperature Rise: Due to significant heat loss, the surrounding environment becomes warmer, especially during summer when it greatly affects production. On-site working temperatures can exceed 45°C, leading some companies to use air conditioning to lower temperatures, which in turn results in secondary energy waste. 3. Short Lifespan and High Maintenance of Traditional Heating Coils: Traditional heating coils, which use resistance wire for heating, can reach temperatures of several hundred degrees for extended periods, causing the resistance wire to easily burn out due to high-temperature aging. As a result, the lifespan of commonly used electric heating coils is not long, leading to a relatively large amount of maintenance work. 4. Advantages and Features of Electromagnetic Heating Systems: 1. Significant 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 generally between 50-80°C, and rigorous testing shows energy savings of 30%-80%, with more significant savings for high-power injection molding machines. 2. Notably Reduced Workshop Temperature: The use of a high-frequency heating system not only improves energy efficiency but also reduces the workshop temperature, creating a more comfortable working environment for employees. 3. Rapid Heating and Accurate Temperature Control: Traditional resistance wire heating involves the wire producing high temperatures first, then slowly transferring heat to the barrel center, which is slow and inaccurate. In contrast, the high-frequency heating system causes the metal barrel to heat itself, with the heat generated by the entire barrel metal. This provides real-time accurate temperature control, consistent barrel internal and external temperatures, and significantly improves product quality and production efficiency. 4. Long-term Operation in Harsh Conditions: Traditional resistance wire heating in plastic injection machine barrels can be compromised in environments such as oil contamination at the heating location, poor metal heat conduction in the barrel, and leakage phenomena. Since the high-frequency heating system does not generate heat itself, it does not carbonize oil or plastic particles on its surface, preventing electrical leakage and short-circuit faults. 5. High Heating Power: Traditional resistance wire heating in plastic injection machine barrels can cause significant damage to the wire at high powers, leading to rapid evaporation and aging of the metal, necessitating frequent replacements. In contrast, the high-frequency induction heating system only generates high temperatures in the induced barrel metal, resulting in minimal electrical losses. Therefore, even at high powers, it does not affect the lifespan of the high-frequency heating system and can adjust the power usage as needed.
