Transitioning to electromagnetic heating to reduce energy consumption and enhance thermal efficiency is an inevitable trend in the plastic industry. Benefits of plastic machinery electromagnetic heaters: Currently, the heating method used in plastic processing machinery on the market is the traditional resistance heating coil, which heats up and then transfers the heat to the barrel. Since only the heat adjacent to the inner surface of the barrel is transferred to the barrel, while the heat from the outer circle is mostly dissipated into the air, this results in significant heat loss and an increase in environmental temperature. Electromagnetic heating technology, on the other hand, causes the metal barrel to heat itself, and the barrel is wrapped in insulation materials, greatly reducing heat transfer loss and heat dissipation into the air, thereby improving thermal efficiency and avoiding the rise in environmental temperature. Consequently, the energy-saving effect is very significant, ranging from 30% to 75%. Because the electromagnetic heating coil itself does not heat up and is made of insulating materials and high-temperature cables, there is no issue of the resistance wire in the original heating coil oxidizing at high temperatures and shortening its service life. This technology offers advantages such as long service life, fast heating rate, and minimal need for maintenance, which reduces maintenance time and lowers costs.
