The core advantages of upgrading the grey hardboard production line are reflected in four dimensions: efficiency, cost, flexibility, and quality:

1、 Efficiency improvement

Doubling production capacity: The modern 2.8-meter wide production line has a vehicle speed of 300-350 meters per minute, which is 1.5-2 times that of traditional lines, and the annual production capacity of a single line exceeds 200 million square meters.

Automated operation: The grey board linkage line supports 1-2 people to complete the cutting and adjustment of the machine, and quickly switches production tasks after parameter settings.

2、 Cost optimization

Raw material utilization rate increased by 5% -10%: ultra wide format reduces cutting edges and corners, especially suitable for multi size mixed arrangement.

Energy consumption reduction: Equipped with a heat recovery system, the steam consumption per ton of paper is reduced to 160-180kg/t.

3、 Enhanced flexibility of the automatic 4 ply grey board production line

Small order adaptation: Supports small batch production of 100-1000 pieces, shortening the sampling to mass production cycle to 2-3 days.

Quick changeover: The NC longitudinal cutting and pressing machine is combined with a double-layer cross cutting machine to achieve multi size switching at a high speed of 350m/min.

4、 cardboard production line Quality stability

Strength improvement: The edge compression strength (ECT) is increased by 5% -10%, the rib shape is full, and the stacking load-bearing capacity is significantly enhanced.

Precise control: Constant temperature hot plate+tension closed-loop system ensures uniform corrugated forming and reduces local deformation.
