Continuous improvement of corrugated box production quality management (1)

The continuous improvement of quality management is a systematic project. It regards the improvement of products and processes as a dynamic quality management process, and the quality is gradually improved and perfected in the continuous improvement process. The so-called continuous improvement refers to the continuous improvement and improvement of equipment, raw materials, production processes, and personnel according to requirements. The continuous improvement of quality can continuously improve the product quality of packaging companies, reduce the production costs of packaging companies, and increase the competitiveness of packaging companies.

Continuous improvement of quality must rely on quality improvement tools including: process analysis, checklists, histograms, control charts, Pareto charts, scatter plots, causality diagrams, and more.

Process analysis

As a basic flow chart, it shows the process of a production process from input, production, and output, and clearly lists each step in the production process. It can help staff find problems in those places and solve problems with them. For example, the process of the packaging manufacturer's factory A is as follows:

checklist

The checklist is a simple quality management tool that provides workers with a check format that facilitates the collection, recording, collation, and analysis of data. There are many types of checklists, and two commonly used ones are: one is a defect location checklist, and the other is a defect type checklist. For example, the defect type checklist for a carton manufacturer of a packaging manufacturer (see table):

By analyzing the table to find the type of defect and the time of occurrence, analyze the cause of the defect and correct it.

Histogram

The histogram is a map showing the probability of the problem occurring within the distribution range. From the chart, you can know the level of those problems and decide whether to take corrective measures to improve. The above table uses a histogram to represent the following:

Through the histogram, it can be known that the problem of corrugated cardboard and cardboard in the factory of the carton manufacturer is relatively prominent.
