The carton production department refers to each production section that produces cardboard into cartons. The loss of the carton production department usually refers to the loss rate of cardboard; the unit square usage of ink; the consumption of printing plates and fonts; the consumption of various knives, things and auxiliary materials. Energy consumption is also regulated.
There are many factors that affect wear and tear. Different order structures, different product quality requirements, different equipment accuracy, different personnel's technical capabilities and personnel's sense of responsibility, different management methods, different production plans and scheduling, different product processing complexity and processing procedures How much will affect the consumption of carton production department. The following is only the control points of the problem that affects the large consumption of the carton production department, and talk about the author's views.
Reasonably arrange production scheduling and control the amount of cardboard and ink
The printing machine (or printing slotting machine) process is usually the most important process of cardboard loss in each carton factory. The ink is also a process that the carton production accounts for a relatively large production cost. For carton factories with multiple printers, this process is the key process for loss control. When arranging production or production scheduling, we must fully consider the accuracy of the equipment, the production capacity of the equipment, the technical level of the personnel, the status of the cardboard, the color number and color sequence of the printing, and the quality requirements of the printing, so as to arrange the production reasonably.
For production scheduling, it is generally necessary to make arrangements for the production sequence of each machine, which can reduce the number of washing machines, reduce the waste of ink, and improve production efficiency. According to the order structure, the corresponding test board and consumption indicators are given. At the same time, the corresponding test methods are established to achieve the purpose of improving the utilization rate of cardboard, reducing the amount of ink, and controlling the consumption. For example, if an enterprise adopts the above-mentioned principle, only one item of ink is used, and in an environment where the order structure is not much related, the original ink used per square meter drops from 2.25g to 1.97g. If a carton of 10 million square meters is produced per year, only one ink per year can save 2800kg. An average of 15 yuan / kg per kilogram of ink can save about 42,000 yuan.
In the control of the utilization rate of paperboard, the adoption of setting indicators, changing the machine hanging version, sticking version, and establishing incentive mechanisms have also achieved obvious results.
Control of consumption of production accessories
In the carton factory, packing tape, offset plates (flat yarns are not included in the analysis for the time being), double-sided adhesive tapes for pasting offset plates, etc. are all auxiliary materials used for production. The following only talks about my views on the control of these main auxiliary materials.
Each supplier of packing belts has different specifications and prices. Generally, carton manufacturers generally use recycled or low-tension packing belts with lower prices and larger thickness and width. In the selection of specifications, uniform specifications are also adopted in order to save trouble.
This will result in greater waste in actual use. In actual use, packing belts with different widths or different prices can be delineated according to the specifications of the packaged products, the quantity and weight of each package. This item is indeed a loss control item that cannot be ignored.
The double-sided tape used in carton factory to paste the offset plates should be different under different conditions of use, and there are not many people who really know how to use double-sided tape. These problems are not easy to attract the attention of typesetting personnel. Most manufacturers use whatever they have, and they never consider the impact of double-sided tape on printing quality. In this way, when the high-density double-sided tape is used, the low-density is used, and the hard double-sided tape is used and other double-sided tape is used, which causes increased wear. Therefore, the carton factory should choose the double-sided adhesive tape suitable for production needs, and formulate the corresponding use method and scope.
Generally, the second-class carton factory has rubber engraving personnel or laser engraving machine. Manual engraving or laser engraving is not a difficult problem for the rational use of plate materials, and general engraving staff will do it. The loss of engraving should not seem to be a critical issue, but in the actual operation process, sometimes although the engraved layout meets the printing requirements, it will be shifted when the actual imposition or typesetting directly on the machine , Thereby wasting time, wasting paperboard, wasting ink.
Therefore, if the standardization of typesetting is completed well, the reduction of product cost is also an important aspect that cannot be ignored.
