According to the purpose of inspection, it can be divided into control inspection, receiving inspection and quality organization inspection and identification.
On the premise of ensuring the quality of carton products, carton companies can set up quality inspection institutions and equip quality inspection personnel according to local conditions. Process inspection generally has the following forms: first article inspection, first article inspection is a preventive inspection in the manufacturing process of carton products, which is suitable for a large number of types. The first article inspection shall be personally inspected by the operator and approved by a full-time inspector.
Patrol inspection is a mobile inspection of product quality in related processes by inspectors at the production site within a certain time interval. The completion inspection is to inspect a batch of processed products, mainly referring to the products between each process. Finished product inspection is the last inspection before corrugated box products reach the user.
Product physical quality audit:
The content of the physical quality audit of carton products is as follows:
Classify the quality defects of cartons into heavy defects and light defects, and write detailed inspection items. After the actual audit, the quality defect items and audit results should be recorded. The quality defects should be analyzed in time, and the carton quality audit report should be filled in as much detail as possible, and the audit results should be reported to the supervisor and relevant departments, and delivered and filed in time as quality information and materials.
Production site quality control:
Create a good production order and environment. Keeping the production site clean and hygienic is also an indispensable condition to ensure the quality of cartons. Factors such as work area, utensils, product stacking and general transportation, worker operating environment, and site cleanliness have an important impact on the production and production of corrugated boxes. should be specified. Therefore, the corrugated box production site can be effectively controlled through point-to-point. Its measures are: formulate corrugated box production site management standards, regular inspection and evaluation, site, machines, equipment, raw materials, construction in progress, workstations and equipment positioning. Take effective measures to reduce the damage caused by bumps, scratches, pollution and rough loading and unloading during the handling of cartons. Semi-finished products and work-in-progress should be listed and marked: especially products coming out of the cardboard line without printing. If they are not listed and have similar breeds and specifications, it is easy to cause confusion and mistakes.
Control and corrective measures for non-conforming products:
Control and labeling of unqualified products: unqualified corrugated cardboard and cartons should be marked, and should not be mixed with qualified cardboard and cartons. It should be isolated and placed in a designated area, and cannot be used, transferred or mixed with qualified cartons without approval. There are four ways to deal with substandard products: rework, scrapping, making accessories and selling at a reduced price.
Corrective actions for non-conforming products. For batches of unqualified products, a quality accident report form should be filled in to find out the root cause of the quality accident, and take corresponding measures to effectively control it to avoid similar accidents from happening again. At the same time, assign special personnel to be responsible for the implementation of each measure, supervise and inspect the implementation of these measures, and see whether the goals are achieved. And archive the implementation results of measures and technical modifications.
To grasp the quality of corrugated boxes, we must start with the quality control of the corrugated box production site, focus on quality prevention, supplemented by quality control, combine prevention and inspection, eliminate factors that affect quality in the production process, and continuously improve the quality of carton products , reduce the loss of each link, and ultimately improve the economic and social benefits of the enterprise.
