Many customers have recently been asking why we haven't promoted machines with electromagnetically heated rollers. Regarding this, the following provides a detailed analysis of the current state of electromagnetically heated rollers compared to traditional heated rollers.
If you're looking for efficiency and energy savings, don't focus solely on electromagnetically heated rollers. Current electromagnetically heated roller transfer machines on the market have numerous drawbacks: poor stability. After prolonged use, the roller temperature often fluctuates by more than 20 degrees Celsius, leading to significant color shifts. They are also picky about fabrics and can't adapt to all fabrics at high speeds. They also have high manufacturing costs and prohibitive maintenance costs. Their principle is similar to that of a household induction cooker, with coils inside. Once a coil fails, it's extremely difficult to repair, costing over $3,000 per repair. Their durability is poor, and ongoing maintenance costs are prohibitively high. Consequently, many are adopting a wait-and-see approach.
In contrast, adopting a dual-roller structure and adding a power regulator to the roller transfer machine offer a more efficient and energy-efficient solution. It stabilizes voltage, preventing energy waste caused by overvoltage and undervoltage. It adjusts heating and motor power in real time based on material and speed, reducing energy loss associated with a "big horse pulling a small cart." It also reduces motor starting inrush current and harmonic interference, enabling on-demand energy supply. While this may increase costs, it's significantly lower than the cost of electromagnetic rollers, offering significant cost-effectiveness.
