Facing increasingly fierce
market competition, corrugated cardboard box companies need to improve the
corrugated cardboard production line The degree of automation, improve the
production management level of corrugated cardboard production line, to achieve the purpose of improving quality, improving efficiency, saving energy,
savingman power, reducing consumables, and reducing waste products. Among them, cadree quipment is the key to achieve this purpose. The cadre equipment should
befully upgraded and transformed, and the new production line should be
equipped with fully automatic cadre equipment with a production management
system.
