- Efficient binding: The hot glue binding device supports ultra-thick bindings of 1-50 mm, processes 500 sheets at the same time, and offers three-stage temperature control (60 seconds / 120 seconds / 210 seconds) to adapt to different paper thicknesses. PTC ceramic heating preheats in 3 minutes, and binding speed reaches 100-200 copies/hour, significantly boosting office efficiency. - Intelligent protection: Automatically shuts off after 30 minutes without operation; includes 10-minute file storage and heat stop. The built-in microcomputer precisely controls the time to prevent glue overflow and overheating, providing a safer operating experience. - Fast heat dissipation: Ventilation slot and rear heat dissipation port ensure even and efficient heat dissipation, rapid cooling of the PTC ceramic heater, and support for continuous work without jams. Fully intelligent temperature control and CPU program control contribute to a long service life and stable performance. - Portable and simple: Lightweight 4.1 kg and compact 38 x 23 x 18 cm. The left rear switch is ergonomically designed with a one-button start function and three speed settings. Comes with an instruction manual and a table of binding parameters for quick setup, so beginners can start quickly. - Practical applications: - Office: bind large batches of thick reports and proposals up to 50 mm. - Education and training: assemble manuals, handouts, and student project binders. - Small business: create product catalogs and client-ready binders.
