The Sunfung SF-340PRO series redefines the benchmark for modern on-demand perfect binding. It delivers premium-quality book binding with fully automatic setup functions at a cost-effective price, setting a new industry standard for desktop binding equipment.

The SF-340PRO features full automatic self-adjustment. Both the pneumatic clamp and nipper operate with automatic calibration, and a built-in silent compressor comes as standard. Operators can switch between binding ultra-thin documents and thick books instantly, with zero manual adjustments required. The machine supports binding thickness ranging from just two sheets of paper up to 6cm.

Fitted with heavy-duty custom roughing blades, this binder effortlessly processes diverse paper materials, including offset paper, coated stock, and paper printed with oil-based or wax-based inks, delivering stable and reliable binding results.

Equipped with twin glue rollers plus an auxiliary metering roller, the equipment ensures uniform, smooth glue distribution across book spines. An independent side glue tank is specially designed for cover hinge bonding, enabling the production of neat, square-backed books and notepads.

This high-efficiency binding machine achieves a maximum output of 400 books per hour. It inherits all core functional advantages of professional binding devices, while integrating multiple upgraded configurations. Standard accessories include an automatic creasing cover feeder, paired with either a vertical book stacker or output delivery conveyor. It also comes with a vacuum waste removal system, which matches heavy-duty notching pins to optimise spine grooving and strengthen glue adhesion.

Adaptable for all batch sizes, from single custom jobs and small batches of 500 units to large-scale orders of 5000 units, the SF-340PRO delivers exceptional usability. It eliminates jams and manual setup work entirely, achieving true one-touch automatic perfect binding for diverse production needs.
