Accu-shape Precision in Die-Cutting: A Guide to Quality and Efficiency

In a comprehensive exploration outlined in the article “What to Know About Die-Cutting” by Paperboard Packaging, unveils the intricacies of achieving impeccable results in the die-cutting process. Beyond the act of cutting itself, the steps preceding and following cutting play a pivotal role in determining the quality of cartons and the overall efficiency of production.

Layout, often underestimated, emerges as a crucial consideration. Accurate blank layout on the sheet is imperative, as an incorrect arrangement can adversely affect multiple downstream processes like cutting, blanking, stamping, and finishing. Accurately laid out cartons empower operators to optimize run speeds, establishing the foundation for a successful production run.

The significance of pre-makeready and makeready cannot be overstated in maintaining operational continuity. An efficiently executed makeready process keeps die-cutting presses in constant motion, minimizing downtime. The pre-makeready team’s meticulous preparation of tooling, die boards, blankers, and strippers ensures seamless transitions between jobs. This allows press operators to swiftly switch tooling, minimizing setup times and maximizing production throughput.

Blanking, the ultimate phase of the cutting process, assumes paramount importance. It involves stripping waste, arranging blanks for folding and gluing, and bypassing manual stripping. While essential, blanking presents challenges for most converters. Struggles may arise from factors like slippery coatings and subtle variations in the distribution of cutting rules or embellishments, leading to uneven stacking of cartons. Overcoming these hurdles demands expertise. Cartons with slick coatings may slide uncontrollably, posing stacking difficulties, while those with selective embellishments may exhibit irregular stacking patterns. In such instances, reverting to traditional air hammer stripping may prove more effective.
