In the carton die-cutting process, we often encounter many problems, if these problems are not handled well, it will affect the carton printing, causing incalculable losses. Problems in the carton die-cutting process are as follows.

1. poor printing and cutting accuracy

With the continuous improvement in the quality requirements of printed cartons, carton packaging design is becoming more and more complex. Complex carton template correspondingly increases the printing and die-cutting accuracy requirements, in order to maintain the error range of ± 0.15mm, qualified die-cutting machine is essential, while paying attention to the adjustment.

2. the replacement template time is too long

Before replacing the carton template needs to do a good job of preparation. With the centerline of the equipment as a reference, you can easily set up accurate die-cutting tools, including carton full-size template, pre-press die-cutting plate. Also, the pre-assembly process of die-cutting tools and fine-tuning the machine reduces the time for repeated adjustments. Usually changing templates for the same carton including automatic stripping can be done in less than 30 minutes with a good management system.

3. Too many connection points

Carton end-users always ask for smaller connection points, and manufacturers always make faster machines, which makes operation more difficult. To reduce the difficulty, the connection point should be a stress point, use a grinder with a hard strip or cork on the knife to prevent the connection point from breaking, and the connection point can be smaller and smaller.

4. High rejection rate

Many printers usually have a very high rejection rate. There is some waste in the die-cutting adjustment process, which can be reduced by using the right tools and the right steps. Waste caused by stopping the paper jam during the run, proper alignment and accurate tool preparation can reduce scrap rates. In addition, manual waste removal will increase waste and reduce profitability.

5. poor die-cutting quality, furry

Poor quality cardboard, such as recycled cardboard that makes the die-cutting step more difficult. To obtain better cutting quality, the operator must develop the correct preparation method to keep the cutting knives sharp by gradually increasing pressure and partial pressurization. For cartons with many cutters, it is important to balance the template, which significantly reduces the time for pressure compensation. In addition, choose strips of different hardnesses according to the requirements of different products, such as step and repeat and cardboard quality.

6. Irregular indentation lines

Considering the need of folding and gluing, the cartons must have good indentation lines. More importantly, these boxes must have a stable and consistent opening force when running on the automatic packaging machine. In this way, choosing the right type of creasing line is an essential element when die-cutting. By choosing the height and width of the creasing line according to the thickness of the paper and fitting the right line on the cutting board, higher quality can be achieved and the boxes can be easily folded.

7. Low production speed

Many carton printers die-cutting machine die-cutting speed is relatively slow, such as 2000 to 3000 sheets / hour, some printers die-cutting machine cutting speed can reach 7000 to 7500 sheets / hour. With modern automatic cutting machines, operators can easily reach maximum production speeds. The production speed is optimized with the tools recommended by the equipment manufacturer. In addition, it is possible to achieve a high quality product.
