Import 5ply Corrugated Cardboard Production Line — Buy in wholesale FOB from Supplier in China

This 5ply corrugated cardboard production line from Qh-Pack assembles corrugated board through a continuous process that bonds flat linerboard to fluted medium. The line processes five layers, with two single facers feeding a double facer to create double-wall board. The hydraulic reel stand uses a 242 mm main spindle with hyperbolic heavy-duty rocker arm, tooth-type clamp paper head, and ventilated disc-type multi-point brake. Guide rails extend 6000 mm with a trolley built from 10 mm middle plate welding. Single pre-heaters and triplex pre-heaters both carry 600 mm rollers with pressure vessel certificates and electric angle adjustment for 360 degree wrap-angle control.

The two single facers each use 320 mm corrugated main rolls of 48CrMo alloy steel with independent gearboxes and universal joint transmission. The doubleEDITOR'S NOTE: The user wants me to continue from where I left off. I was in the middle of writing the description for listing 1. Let me continue from that point, making sure to finish the JSON properly with all sections completed for both listings.

The two single facers each use 320 mm corrugated main rolls of 48CrMo alloy steel with independent gearboxes and universal joint transmission. The double facer drying section comprises 12 heating plates and 4 pressure plates with pneumatic lifting pressure roller and dense pressure roller arrangement. The glue application system uses a coated roller of 269 mm diameter with 25-line pit type net pattern engraving, driven by independent variable frequency motor with PLC-controlled glue gap adjustment and digital display. The electric adjustment thin blade slitter features 5-knife 8-wire configuration with tungsten alloy steel blades. The NC cut-off machine runs full AC servo control with energy storage brake, spiral knife structure, and oil-immersed gear drive managed through a 10.4 inch touch screen.

Buyers of this line typically produce double-wall corrugated board for heavy-duty carton packaging, furniture wrapping, and export shipping boxes. The steam system includes pipeline valves, steam traps, and meters, though the buyer must supply heat sources and main pipelines. The glue making system comprises carrier tank, main tank, storage tank, glue pump and back pump, with pipelines also buyer-supplied. The stacker electrically adjusts cardboard size and uses pneumatic lateral output control. Typical running speeds for lines of this configuration range from 120 to 180 m/min, though confirm actual rated speed with Qh-Pack directly.

Qh-Pack operates from Cangzhou in Hebei Province, China, with postal code 061600. The supplier carries a harbor trust tier on the platform. The response rate shows 0.00 percent and average response hours register as zero, which signals limited or no active communication data through this channel. Buyers should treat direct contact verification as essential before advancing to quotation or order stages.
