1. Smart Sensor The smart sensor adjusts adhesive time via temperature control, accommodating any paper thickness from 1 to 500 sheets. It ensures fast binding, effortless operation, and prevents document damage. The ABS plate and allmetal handle are durable, heatresistant, nontoxic, and designed for longterm use. 2. Firm Binding Securely clamp the hot melt cover before binding to prevent the first and last sheets from loosening, ensuring full contact with each side for a tight bind. The open cooling groove design allows rapid adhesive cooling, resulting in a firmer binding. 3. Technical Data Power: 100W; Binding Size: 310 x 50mm (A3 short edge, A4, A5); Binding Thickness: 1–50mm; Preheating Time: 3 minutes; Maximum Capacity: 500 sheets of 70g paper. 4. PTC Heating Equipped with 100W PTC ceramic heating technology for even and efficient heating. The intuitive control panel and builtin CPU programs with infrared photoelectric detection simplify binding. Automatically switches to standby mode after 15 minutes of inactivity.
