To prevent material cracking during the Die Cut process, the first critical step involves optimizing Creasing parameters and utilizing matrices that precisely match the board thickness. Cracking typically occurs when the board fibers are overstretched or when the Grain Direction is ignored during the structural design of the package. To resolve this, consultants suggest using advanced make-ready systems and rounder-edged scoring blades to distribute pressure more evenly across the fibers. This ensures the material bends without fracturing the outer liner of the substrate.

Additionally, controlling the moisture content of the material before die-cutting is vital; overly dry paperboard loses its elasticity and becomes highly susceptible to edge fractures. In professional production environments, implementing the correct Ejection Rubber hardness around the blades assists in a uniform release of the sheet from the die, preventing stress concentration in sensitive areas. By maintaining these technical settings and monitoring press pressure, manufacturers can minimize production waste and guarantee the final structural integrity of the packaging for the end consumer.
