how to solve corrugated board warping when die cutter

compared with the single machine, corrugated board production line has the advantage of high efficiency, high speed, good quality, but the disadvantage is prone to warping, which has brought many difficulties to the next procedure production, such as printing, slotting and die cutting, corrugated board with serious warping can not be produced in the next procedure, resulting in products scrap, production cost increase, affecting the quality of the products, at present, corrugated board produced by corrugated board production line has generally four types of warping as follows:

  1. upward corrugated board warping
  2. arched upward corrugated board warping
  3. downward corrugated board warping
  4. arched downward corrugated board warping.
