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.

Solving the die-cutting dilemma for large packaging needs

When producing packaging materials, a common process used by the industry is die cutting. Die cutting is a process where low strength materials (such as paper, corrugated fiberboard, cardboard, fiber, foil, plastic, etc.) are cut through a die. What makes the die an integral part of the process is its ability to cut pieces with a specified shape. The consistency and accuracy of the die and die cutting process itself allows industries and their respective businesses to maximize aesthetically pleasing and unique packaging products. They can even obtain products with different shapes and profiles and multiple layers of complex cuts. In addition, they can get the packaging materials they need in a very short period of time, as the die-cutting process can produce large quantities of these materials at once. With these benefits, companies that perform die-cutting processes can certainly help companies get the packaging materials they need. If you are looking to source a large amou...
