Import Double Facers — Buy in Bulk from Supplier in China

The SM3 Type Double Facer is a corrugated board production machine designed for high-speed lamination of linerboard and medium into triple-wall or double-wall board. It features a grinding-finished heater plate measuring 150mm in height and 600mm in width, available in configurations of 16, 18, or 20 plates. The system uses concentrated press rollers and hydraulic actuation to control vertical pressure, enabling precise adjustment by section based on board layers.

Heating is achieved through steam pipes arranged in grouped zones, allowing independent temperature control per section based on paperboard thickness and line speed. The upper cotton belt includes an automatic error correction system and dual pneumatic tension units, while the lower belt uses an S-shape manual tension mechanism. Optional features include air-cushion spray steam heating, gravity pressing rollers, and PLC-controlled press plate quantity adjustment.

This machine is targeted at medium to high-volume corrugated packaging manufacturers requiring consistent board quality at speeds up to 180m/min. Buyers typically specify the number of heating plates, type of pressing system, and automation level.
