Analysis Of Process Control In Paper Packaging And Printing Enterprises

        The difficulty of quality management in paper packaging and printing enterprises is process control.      This is determined by the characteristics of paper packaging and printing: there are a wide variety of products, covering almost all commodity categories; Orders vary greatly in length, ranging from hundreds of thousands to hundreds of thousands; Analysis Of Process Control In Paper Packaging And Printing Enterprises

        The process routes of products are different. Some have only two or three processes, while others have more than a dozen; The production process is mostly single machine operation, which is difficult to realize the on-line assembly line production from beginning to end.Analysis Of Process Control In Paper Packaging And Printing Enterprises

       After one process is completed, it is transferred to the next process, repeated paper feeding, repeated paper receiving and school bus for many times; Analysis Of Process Control In Paper Packaging And Printing Enterprises

       The control conditions are relatively easy to change, and there are many human factors. Based on the above characteristics, compared with other industries, paper packaging printing can be described as a “semi-automatic” industry, and the constant control of its process is more difficult.Analysis Of Process Control In Paper Packaging And Printing Enterprises

       From the perspective of data, the basic situation of quality control of domestic paper packaging and printing enterprises can be described as follows:

 

Prepress: basically realize data control.Analysis Of Process Control In Paper Packaging And Printing Enterprises

 

Printing: some enterprises realize data control.

 

Post press: only a few enterprises realize data control.Analysis Of Process Control In Paper Packaging And Printing Enterprises

 

From the perspective of implementing ISO9001 quality system, the basic situation can be described as follows:Analysis Of Process Control In Paper Packaging And Printing Enterprises

 

Formally, a considerable number of paper packaging and printing enterprises have implemented the management of ISO9001 quality system, but in essence, only some enterprises can deeply understand the connotation of ISO9001:2000 system and effectively implement it.

 

       In comparison, European and American enterprises pay more attention to system management and hope to use the system to guide and restrict operators to control the production process, Analysis Of Process Control In Paper Packaging And Printing Enterprises

      while Japanese enterprises emphasize the sense of responsibility and professionalism of employees in their posts, so as to control the production process through higher personal work quality. 

       At present, most of China’s printing enterprises follow the management mode of European and American system, while they have relatively little understanding of the management mode of Japanese enterprises. Here, we only describe the quality management of Japanese enterprises for reference only.Analysis Of Process Control In Paper Packaging And Printing Enterprises

 

       At first glance, the quality management of Japanese paper packaging and printing enterprises has a feeling of “self-employed”, lack of a very sound quality management system, and even lack of the quality management department of “having a certain number of personnel” emphasized by European and American enterprises. Analysis Of Process Control In Paper Packaging And Printing Enterprises

         Mori paper, a representative Japanese paper packaging and printing enterprise, has nearly 150 people in the company with an annual output value of about 400 million yuan, but there is no special quality management department. There are only three people in the company responsible for quality management, of which two are full-time responsible for incoming inspection.Analysis Of Process Control In Paper Packaging And Printing Enterprises

       The company’s printed products are mainly packaged with daily necessities, with a wide variety, including cardboard boxes and corrugated boxes.Analysis Of Process Control In Paper Packaging And Printing Enterprises

        Its production processes include: prepress, printing, bronzing, calendering, window pasting, corrugated mounting, die-cutting and box pasting. From the perspective of technology and equipment, its advanced nature is not the top class, it can only be regarded as a “second rate” standard, but its quality control level is world-class.Analysis Of Process Control In Paper Packaging And Printing Enterprises

 

        Through in-depth communication with the production director of the company and the actual situation in the workshop, we have the impression that Japanese enterprises attach great importance to the responsibility control of this process. This responsibility control is not only limited to quality, but also reflected in production efficiency and environmental 5S. Analysis Of Process Control In Paper Packaging And Printing Enterprises

      This sense of responsibility control is not mandatory, but has formed a habitual specific corporate culture.Analysis Of Process Control In Paper Packaging And Printing Enterprises

 

        In the printing workshop, there are usually five people for two printing machines. When quality problems are found in the printing process, the captain first identifies the problematic prints by inserting strips, and temporarily puts the prints on the pallet aside. When they can be turned over, the machine personnel take time (the machine is still in normal production) to sort them out separately and pick out the defective products, Analysis Of Process Control In Paper Packaging And Printing Enterprises

       Mark well and transfer to the next process with the formal products. There is no so-called “picking large sheets” print sorting group after printing. The same is true for each subsequent process. All problems in all processes are the responsibility of this process.Analysis Of Process Control In Paper Packaging And Printing Enterprises

 

         It is worth mentioning that in the box pasting process, we see that a box pasting machine is equipped with three people, including one Captain (responsible for operating the machine, spot checking the box pasting quality and auxiliary packing), one feeding person and one receiving person. When the speed of box pasting locomotive is 60000 / h (200 face towel cartons), they are also responsible for packing, sealing, labeling and stacking pallets.

          If you don’t see it with your own eyes, you don’t believe it. In addition, there is no need to reload the paper between the processes. When the material is received in the previous process, the paper has been piled up. In the next process, the whole pallet can be directly pushed onto the machine to start operation, which is also the result of the implementation of responsibility control in this process. In the whole production process, there is no inspector to “help” the operator to close one more pass. Analysis Of Process Control In Paper Packaging And Printing Enterprises

      The company does not even have a final inspection before leaving the factory. The Japanese are unique in the world in being picky about the quality of packaging. Even so, the company has only a record of 3-4 returns in the whole year. Such returns are usually optional, rather than fatal annihilation. Therefore, this quality control has been called a world-class level.V
