Production Quality Management of Corrugated Box Enterprises (I)

Corrugated board lean production

In the increasingly fierce towel market competition, corrugated box manufacturers should vigorously promote lean production, improve the level of product refinement, and enhance the competitiveness of their products.

Lean production divides the production process into value-added processes and non-value-added processes. It regards “finding perfection endlessly” as a business standard, pursues continuous improvement in product quality, cost, and service, and observes and analyzes it from the perspective of lean production. The production process, to find the production site of the ineffective labor and waste and to eliminate radical. At present, there is no value-added process in the corrugated box production process in many corrugated box enterprises. Everyone is blind to these wastes and even considers it inevitable.

Corrugated cartons companies must adopt lean productivity to start from the analysis of waste, find the potential for improvement, innovate and improve, use the enthusiasm and creativity of all employees, and constantly improve the corrugated box processes, equipment, operations, management, etc., and formulate effective measures. Gradually eliminate all kinds of waves of praise, eliminating the process of non-value-added production, so that enterprises infinitely close to the perfect realm.

In general, corrugated box companies have developed for themselves at the beginning of the year: multi-coin production indicators such as reject rate, product pass rate, paper utilization rate, etc. Improvements to these indicators are also made through predetermined percentages. Employees have clear goals for improvement and will work hard to achieve these metrics, but few people will exceed these metrics because the better done this afternoon means that the harder it is to improve next year, so employees are only satisfied with completing each metric. , thus hindering the operation of the potential. Lean production requires that the corrugated box manufacturer's production index has no definite quantification, and often takes the best status as the target, such as "zero defect", "zero complaint", "zero fault" and so on. It can be said that it is impossible to achieve these idealized Japanese standards, but it will enable the staff to create a kind of impetus to "limit", establish an unsatisfied and enterprising spirit, and maximize the potential intelligence of employees.

The accuracy and punctuality of logistics and information flow are the requirements of the lean production process. The corrugated box enterprises adopt kanban production and timely delivery so that the raw and auxiliary materials and parts needed for production can arrive on time and meet the requirements. The quality requirements and quantity required. When corrugated cartons companies implement lean production, they can first select key production processes, such as printing processes to carry out the lean production promotion team. Then, with the point and the surface, the production process, printing, binding, and other production processes are fully promoted, and all employees participate in the lean production work.

Corrugated box production quality control

Corrugated box production processes are mainly divided into three major processes: production line, printing and door installation. Here, the three main processes are mainly used to explain the production control process in the production process, the main points of quality control for cattle production, and prone to quality problems, so as to achieve prevention.

Production line process production quality control

The production line process operation control chart (taking a five-layer corrugated cardboard production line as an example) is shown in Figure 1.

Each process of the production line is first self-checked by the process operator, and a process operator at the mountain performs the gate re-test. After the first inspection of the production line leader, the quality inspector seals the sample and confirms it before mass production.

Production line production quality control points:

Production process: c car (or A car)

Production quality control requirements: ensure that the corrugated paperboard and c-watt or A-carton paper are accurate; the corrugated form is not tiled; the bond is firm; the splice part informs the stacking process to pick up the mountain.

Production process: D car

Production quality control requirements: Ensure that corrugated cardboard core paper and D-watt paper are accurate; corrugated molding is not inverted tile;

Production process: compounding and drying board

Production quality control requirements: to ensure that the corrugated cardboard face paper is accurate; corrugated molding is not inverted tile; firm adhesion, no foaming.

Production process: vertical and horizontal

Production quality control requirements: Ensure that the size of the corrugated board and the size of the flap pressure line are accurate; there is no obvious burr on the cardboard edge, the knife edge is smooth; the depth of the indentation is moderate.
