Chapco's new hope

(Chapco turns a corner) Chapco Carton recently purchased a seven-color Mitsubishi sheet-fed press, turning the company's operations into a turning point. Chapco Carton Company is a company that prints and produces folding carton boxes. It mainly prints boxes for all kinds of products. This forces them to upgrade the machines that can only produce single-shape box shapes so that they can produce more types of packaging products. . So they spent a considerable amount of time changing the old presses. According to this idea, Chapco needed to find a press that could automate prepress preparation to increase production. At this time, Mitsubishi offset press manufacturers introduced a press that can produce seven wide-width folding carton packs with automatic prepress preparation. Chapco then purchased a 56-inch wide Mitsubishi 6FC-7 press. Chapco not only got the required press but also got the technology. This machine runs at a speed of 12,000 sheets per hour and is particularly suitable for folding cartons. 80% of the substrates are recycled cardboard, 20% of the original cardboard, and occasionally printed on metallized polyester plates. The ink is a plant-based ink from Gibbon Ink Company. The entire company's production is very environmentally friendly. As a standard device, the printer's touch screen COMRAC (operator prepress preparation and control center) displays various printing parameters, prepress setup settings, and security operations. In addition to the API III automatic preset system and microprocessor control system, the central console also includes a remote operation positioner for positioning in the longitudinal, circumferential, and oblique directions. A Multi-Sync NEC LCD15T touch screen controls every function on the press. When maintenance is required, a flashing red light will appear on the parts that need to be processed until the red light is extinguished. Up to 500 kinds of job parameters can be stored in the memory. When necessary, the production can be repeated as long as the necessary parameters are recalled. The new machine includes a clamping system with positioning pins, a circulation cooling system for printing units and a roller coated with plasma, in addition to a chrome platen cylinder, a skeleton platen roller, remote control of the cylinder and clamping of crepe paper. Teeth and other standard features. Chapco also added semi-automatic loading/unloading features for the printing plate installation. The plate was mounted on the press and locked firmly on the printer, reducing the time by half. The press also includes an MMT quick-change device and a Delta Graphics wetting roll to effectively avoid some of the defects on the plate. In addition, the Baldwin Quantum 95 wetting system cleans the entire press. The Mitsubishi press also features AWS's single-roller cooling device, which is placed in the tandem roller to help keep the temperature constant. The Graphix North America dryer is a combination of infrared and hot air squeegee. According to the different jobs, the color registration positioning requires only 30-50 sheets of pattern paper, but it usually takes 200-400 sheets to obtain it. Satisfactory results. There are also two Komori presses at Chapco to balance the work load, one of which is a 40-in six-color printer with a coater and the other is a 50-in five-color printer with a coater. The presses are equipped with Komori's standard systems, such as automatic devices, engine drives and page turning operating systems, on each press. With these three printing presses, any business can be followed. It is inappropriate to say that “short-run production is performed with a 40-in press, and the long-term use of Mitsubishi printing press” is mainly dependent on the size of the paper box, and a series of factors such as typesetting and die-cutting are also considered. Chapco also has four die-cutting systems, one is Iberica's die-cutter/embossing machine, and the other three are Bobst Group companies, two of which are also imprinters, all of which can be cut. Stripping and on-line imprinting. There are four gluing machines in the binding shop and two Kohlman windows for the carton are very fast. The other two are four-fold and six-fold folding gluing machines. Recently, Chapco designed and built an electronic computer drive system to remove products from five running gluing machines. The system works well and they also plan to make some improvements to it in order to increase work efficiency. Other innovations include the ability to output film through a computer. In the first half of this year, Chapco will turn to CTP (Computer to Plate), which will keep the company far ahead. For future work, Chapco plans to continue to develop the folding carton market and may enter the small-scale market. Company operators believe that the new equipment and its good performance will enable Chapco to achieve a new level of profit in 3 years, and the overall design of the equipment. , layout, assembly, and technology are necessary conditions for making a dream come true. Other Classical Applications In December 2000, Riverwood International, one of the world's largest beverage packaging plants, installed a K-Patina sheeter with a 56-inch format for seven-color sheets. There is also a twin tower coater on this press. Replaced the two old 56-inch sheet-fed presses with this machine, and the production speed was increased from 4000-6000 rpm to 14,000 rpm, and it was fully automatic, including the replacement of printing plates. Make prepress work preparation time greatly shortened. At the same time, its compatibility makes it ready for companies to introduce CTP at the right time. The coater is a box that can produce soft drinks such as beer and software. This box requires two different types of coatings. This coating is applied to the top and bottom of the carton to facilitate shipping, and for four weeks Packaging should be easy to compress. Over 100 experts in the printing and paper processing industry had a first-hand understanding of the technology and its processes and trends in the packaging field at a special seminar on Inforum. Held at the Heidelberg Printing and Manufacturing Plant headquarters in the United States in November last year. In order to gain benefits in packaging in today's society, we must stand at the forefront of reform, not only in technology, but also in the market, management and process control.
