When evaluating an automatic ironing machine, prioritize heating efficiency and roller diameter. For industrial laundry, a roller diameter of at least 500mm to 800mm is essential for high-speed processing. Ensure the machine features variable frequency speed control to adjust for different fabric types (cotton, linen, polyester). Additionally, check for steam, electric, or gas heating options based on your facility's utility costs, and verify that the ironing width (typically 2500mm to 3300mm) matches your largest linens, such as king-size bedsheets.
