The demands on packaging manufacturers are increasing: high productivity, low machine downtimes and high-quality packaging are all required – regardless of the run length. An essential factor for the necessary productivity is the cutting-rule make-ready.
Find out how you can significantly reduce cutting-die make-ready times to a minimum and so increase your productivity and die service life. For maximum performance when die-cutting your packaging.
The cutting-die is a flat tool: in theory, all cutting rules hit the cutting plate at the same time during the die-cutting process. In practice, however, there are various tolerances which can cause the rules to cut through the die-cutting material in some places but not in others. This is where a height compensation becomes necessary: so-called patching.
But make-ready takes time. And time is money. With ever-increasing demands on packaging manufacturers, ever-smaller runs and thus an increasing number of tools that have to be made-ready, the importance of time savings in the make-ready process is growing enormously.
What is make-ready? - The patching process.
During make-ready, height differences are compensated with the aid of make-ready paper/ tape. This is done on the one hand by levelling out areal tolerances, and on the other hand by placing make-ready tape behind the cutting rules at points where the material has not yet been punched through. A distinction is made between area make-ready which compensates for machine unevenness and a local patching of the cutting rules. Certain make-ready rules must be observed for this. Depending on the job and complexity, the make-ready process can take several hours.
What is make-ready for? – The influencing factors.
There are various tolerance factors that influence the scope of a knife make-ready. These include: the die-cutting machine, cutting-die and counter plate, the paperboard material and the quality of the make-ready materials. But the machine operator and the operation in its turn also have an influence on the make-ready time. Each of these factors in and of itself produces different tolerance ranges.
At the end of the make-ready process, the result is a clean cutting edge for high-quality packaging. Height compensation ensures that the die-cutting machine and tool are protected in the best possible way. This means a longer service life. Clean make-ready also ensures stable machine operation and thus an efficient die-cutting process. Technologies and services from the diemaker can help, but in addition regular training of the machine operators also supports them in efficient make-ready.
In our free whitepaper on "The main success factors for minimimum make-ready time during die-cutting", you will not only learn how make-ready works and what the most important make-ready rules are, but also how you can optimize make-ready time – while ensuring high-quality make-ready. The practical checklist will help you to do this.
