Electric heaters are widely used in the plastic processing industry. In processes such as injection molding, wire drawing, film blowing, extrusion, and pelletizing, energy costs account for a significant proportion of the overall expenses. Electromagnetic heating technology in electric heaters converts electrical energy into magnetic energy, causing the heated steel body to generate heat through induction. This fundamentally addresses the shortcomings of electric heating plates and coils. Additionally, it offers the following advantages:
1. Improved environment: The heating part dissipates minimal heat, and the surface can be touched by hand, improving the working environment.
2. High efficiency and energy saving: Thermal efficiency exceeds 95%. Under the same conditions, it saves 40-80% electricity compared to resistance heating, and preheating time is reduced by two-thirds.
3. Reduced costs: The heating part uses a cable structure; the heating cable itself does not generate heat and has a long service life. This eliminates the need for frequent maintenance and periodic replacement of heating coils required by resistance heating, resulting in virtually no maintenance costs later.
4. Reliable operation: A multi-loop intelligent control system and comprehensive protection system ensure long-term safe and reliable operation of the equipment.
Electric heaters can not only be used in their own products but also bring benefits to other industries, reducing costs and minimizing waste.
