Flexible printing solution for folding cartons

Die cutting and processing

Online rotary die cutting machine

Color reproduction is a costly process in the printing process. However, in the processing of folding cartons, the market share of rotary die cutting continues to grow. Because more and more processors are aware of the advantages of rotary cutting machines and the importance of product quality. At the same time, the continuous improvement of rotary die-cutting machines has enabled die-cutting machine manufacturers to see the cost savings associated with high productivity. And they pass on this cost savings to their customers. Today's rotary die-cutting machines are of good quality and low price, and they are faster than any previous product. Compared with the same steel knife die-cutting platform cutter, rotary die cutters are expensive. The savvy processor knows that its cost is still low, while ensuring high productivity and low resource waste.

Cutting method and die cutting type

There are many kinds of die-cutting methods for rotary die-cutting machines. At present, there is a very effective way to understand the difference between the two for ease of understanding. There are two major die cutting methods in existence. The first one is the most common one. The well-known method is rolling die cutting and the operation is simple. Using a sharp cutting knife and a smooth, sturdy platform, the knife cuts through the cardboard and finishes cutting. This is the most common way for a flatbed die cutter. The second method is supported by a die-cutting mechanism. By applying a rotary pressure to the paperboard, a broken portion is formed and the cardboard fibers are cut. This approach has many product names, but it is usually classified as pressure die-cut.

In order to quickly and accurately sum up the difference in performance and cost between the two die-cutting methods, the cost of the latter die-cutting is roughly twice that of the former. Before the die-cutting media wears out, the pressure die-cutting die-cutting The cartons are more than 10 times more than roll moulding. The most prominent of the existing die cutting methods are rigid die cutting and flexible die cutting. As the name suggests, rigid die cutting is the engraving of an image on a solid steel roller. Flexible die cutting is made from sheet material and adhered to a magnetic roller. Processors usually use rigid die cutting because of their high yield. Flexible die cutting is generally used for low output die cutting or simple die cutting.

Waste disposal and carton transportation issues

The inspection work plays an important role in the production of carton flexo printing. The reason is simple: if the waste cannot be processed quickly, the entire printing production line will slow down. Similarly, the transport of cartons is also the same. High-speed operation can be achieved by installing a device for transporting the carton on the printing press. Many printer manufacturers are trying hard to maintain the low price of the press, but they ignore the two most important aspects, which makes their customers very dissatisfied.

Typically, the press uses a stripping version or a technique called pinstriping to handle the waste generated by the trimming. On the surface, waste disposal is simple, but it can actually lead to more paper waste and longer downtime. Pinstriping does not have a definitive way of avoiding downtime, which can reduce downtime for normal operations and save valuable cardboard in the efficient typesetting utilization of the carton. Usually pinstriping equipment is installed on the printing machine, which can save 2% to 4% of paperboard material.

Most printers save the stockpiles at a predetermined height by collecting blanks and complete product shipments. The operator usually manually puts the packaged product into the box or conveys the finished product to the folding machine/bonding machine to complete the processing of the blank material. Good machine control is the most important. A complete transportation system has a longer life than the printing press, and smart operators know this clearly and increase investment and expand production.

Flexographic printing market advantages

productivity

No one can fully prove that folding cartons are not a commodity. Although our industry wants to see our products more artistic. The folding carton market has formed a commercial industry. If the product is not tested in the commercial market, sales testing will not be successful.
In order to maintain the competitive position of products, processors have to seize any opportunity to reduce costs and increase productivity. Increased productivity means that funds and labor will be fully utilized to minimize costs. Reduce the number of printing steps as much as possible, and reduce the cost of sheet-fed printing equipment. The online web flexographic printing press provides the best opportunities for processors and accelerates the development of folding cartons.

Reduce waste

Cardboard as a carton production line, the largest cost, usually accounts for 60% to 70%. For this reason, any processor hopes to get better-selling products so that they can better resist falling prices. Online web printing press equipment can provide many opportunities for waste savings. Among these opportunities, waste picking devices can save 5% to 8% of paper stock. Other better supporting equipment can save one or two percentage points of waste, reduce the possibility of equipment damage, and save 2% to 5% of the cost, which can add up to 8% to 15% of the cost.

The total amount saved year after year makes the investment in new printing equipment in a good state of funding. When processors see that the waste generated by flexographic printing is reduced and their productivity increased, even if the prices of all old sheet-fed presses have been reduced, they are very skeptical.

Flexo printing press advantages

Online flexographic printing presses come in a variety of different types, sizes, and prices. Evaluating similar products will confuse our experience. Especially in the face of new products, no matter what professional market you have, you should broaden your horizons and look for any new type of press.

Uneven design: Durability includes frame structure and operational design, which is extremely important for the production of folding cartons. Although the "beefed-up" label printer has an attractive price, it is not easy to die-cut.

Printing equipment has the advantage of entering the fast-growing market: The longer the press is produced, the more obvious its advantages. But this is also one of the most basic facts that manufacturers who are trying to sell low-priced devices tend to overlook. To our surprise, the cost of the low-cost equipment used in the long-term operation and uncontrolled use accumulated to its useful life is staggering.

Exquisite processing mechanisms: Presses that do not have the ability to die-cut, strip waste, and transfer cartons have been significantly reduced in price. In the market demand for reduced printer prices, many printer manufacturers and processors have neglected another area.

Training and technical support: There isn't a good car driver, and even the best car won't win the first one. In Indianapolis, USA, manufacturers provide updated technical support. In the initial training, printer buyers should ask some specific questions. The cost of training is paid by the trainee.

From a historical point of view, high-quality printing quality, combined with economic efficiency and productivity, make online web flexographic printing an inevitable choice for carton processors. With the high demands of today's market, many cartons have adopted the "hunker-down" intelligent technology in recent years. Despite the difficult economic environment, they have made bold attempts to invest in more easily-manufactured production technologies. . (Duan Xiaoyu/Translation)
