The die plate design of the carton box

The die plate design is the key part of the folding carton packaging production, it has a direct impact on product quality and cost. It need to consider lots of factors that affect the quality and cost of the carton box, such as step and repeat, bridging, die-cutting process. Factors, such as the box blank arrangement, bypass, die-cutting process etc..

1. Step and Repeat

In order to reduce costs, we must consider to maximize the utilization of raw materials cardboard use rate. Finding ways to use the same area of ​​the cardboard production as much as possible qualified carton boxes, the problem is not step and repeat as much as possible carton boxes on the die plate, because the cardboard pattern limited the boxes step and repeat directions. we can only consider step and repeat more carton boxes in the same direction on the cardboard. The step and repeat process is subject to carton size, the shape the carton box as well as other factors.

2. Bridging

In order to ensure the carton boxes do not come off from the cardboard during the period from die cutting to remove waste, the carton boxes in the cardboard need bridge to connect them together. While remove the waste cardboard, the waste should be easy to apart from the carton boxes, so the bridges can not be too big and too much, else the meaning of bridging will be lost. In a sense, the bridging directly determine the die cutting process can be proceed smoothly.

Obviously the number of bridges also determines the length of the cutting knife.The fewer the number of bridges, the greater the average length of each section of the knife, the knife bending more easily damaged in the process of production, it determines the die-cutting process can proceed smoothly cause the die-cutting production process may cause more frequent downtime during knife replacement.With these considerations, we can appropriately increase the bridges to solve these problems.Increase the number of bridges, can shorten the length of the cutting knife, cutting knife strength increase which is not easy bending. And to shorten the length of each section of the cutting knife, the extent of thermal expansion and contraction are reduced accordingly, the impact of cutting precision is also reduced.

3. The die cutting process affects the die plate design

After decided the carton box step and repeat method, it also need to be considered whether leave spaces between the carton boxes, that is two adjacent edges are stitched together or separately. In the die cutting process, stitch them together or sperate them means whether share the knife or not. Share the knife can be only used when the two boxes blank adjacent edges are straight lines. If there are spaces between carton boxes, the width of the gap should be considered during step and repeat.We can simply divide the width of the gap into two, add them to the side of the boxes respectively.
