Common problems with paper buckets

fibre drum The impact of the quality of the molding process operation on the bottom of the barrel

fibre drum The connection between the barrel body and the barrel bottom during the production process is mainly completed through the bottom sealing and forming process, so the quality of the forming and sealing process affects the overall quality of the paper barrel. After determining the equipment type, it is necessary to regularly check the changes in the dimensions of various parts of the sealing paper mold, because when the mold closes the bottom of the sealing paper barrel, the locking ring mold deviates vertically, causing uneven tightness of the bottom of the paper barrel and affecting the fit between the barrel bottom and the barrel body.

Establish various technical quality management systems and effectively control them

Specifically, it is necessary to establish a management system for the entire production process, including raw material procurement system, key process control system, incoming inspection system, first article inspection system, operator self inspection system, process mutual inspection system, quality inspector inspection system, finished product inspection system, etc. A control procedure for the management system should be established, which includes the methods and procedures for approving, publishing, marking, cataloging, using, changing, retrieving, archiving, storing, and handling the existing system. In the same location where it is necessary to timely issue and revoke obsolete management systems, it should be ensured that each place uses the effective version of the corresponding system.

Process control should be implemented throughout the entire production process

Firstly, the process operation procedures and inspection standards for each process in the production process should be formulated, key processes that affect product quality should be established, and continuous supervision should be carried out to ensure that each process in the production process is under control. The control status of the production process should be effectively reviewed and corrective measures should be taken in a timely manner to solve abnormal situations and problems, and assessment records should be kept.

Establish a system and methods for inspecting raw materials and finished products

Develop a raw material inspection system and record the inspection results. The accuracy and precision of the testing equipment should meet the inspection requirements and be checked regularly. The process inspection includes initial inspection, self inspection, mutual inspection, and patrol inspection, with clear records.

The methods of product inspection are mainly divided into two parts: appearance inspection and performance inspection, and the internal control indicators of the inspection should be higher than the national standard indicators. The following describes the inspection methods, requirements, and guidelines for paper drums.
