The issues in the carton box die cutting process

In the carton box die cutting process, we offen encountered lots of issues, if these issues can not being handled, it will affect the carton box printing and may cause immeasurable loss. The issues in the carton box die cutting process listed bellow:

1. Take too long time to change die plate

The preparation work need to be done before changing the carton box die plate. Use the center line of the device as a reference, you can easily set precise die-cutting tools, including carton box full-size die plate, pre-load die-cutting plate. Mean while, the die-cutting tools pre-installed process, fine-tuning the machine also reduce the repeated adjustment time. Usually changing the die plate for the same carton box including auto-stripping, can be completed in 30 minutes under good management system.

2. Poor accuracy of printing and cutting

With the increasing requirements of high quality on the printed carton box, the carton box packaging design is becoming increasingly complex. Complex carton box template correspondingly increased the precision requirements on printing and die cutting, in order to maintain the error range of ± 0.15mm, qualified die-cutting machine is essential, at the same time pay attention to adjust it.

3. Poor quality of die cutting and hairy

Low-quality cardboard, such as recycled cardboard which makes the die-cutting step more difficult. To achieve better cutting quality, operator must be worked out correct preparation methods, by the method of gradually increase pressure and regional add pressure to maintain the sharp cutting knife. For the carton box use many of knives, balance die plate is very important, and it can significantly reduce the time of the pressure compensation. In addition, in accordance with the requirements of different products, such as step and repeat, cardboard quality, select different hardness strips.

4. Too many connection points

The carton box end user is always require the fewer the smaller connection points the better, while the manufacturer always makes faster machine speeds, thus increasing the difficulty of the operator's. To alleviate the difficulty, the connection point should be the stress points, use the mill-ray machine with hard strip or cork on the knife to prevent the connection point breaks, the connection points can be smaller and fewer.

5. Irregular creasing line

Taking into account the needs of the folding and gluing, the carton box must have good creasing line. More importantly, when these boxes run on the automatic packaging machine, the open force must be stable and consistent. In this way, select the appropriate type of creasing line is the basic elements during die cutting. Depending on the thickness of the paper, choose the height and width of the creasing line, the appropriate lines bonded on the cutting plate, it is able to reach a higher quality and the box is easy to fold.

6. Low production speed

The die-cutting speed of the die cutting machine in many carton printing factories are relatively slow, such as 2000 to 3000 pieces / hour, some printing factories the die cutting machine cutting speed could up to 7000 to 7500 pieces / hour. The use of modern automatic cutting machine, the operator can easily reach the highest production speeds. To optimize the speed of production through the recommended tools by the equipment manufacturer. In addition, it can reach a high quality product.

7. High rejection rate

The rejection rate is usually very high on many printing factories. There will be some waste during die cutting adjustment, which can be reduced through the use of the right tools and the right steps. During the operation the waste caused by shutdown and blocking paper, correct alignment and accurate tool preparation can reduce the rejection rate.In addition, the artificial cleaning waste will increase waste and reduce the profit rate.
