Step 1: Develop key control points for production quality
1.Quality loss caused by marketing process
Sometimes when making plastic flexible packaging , the customer's requirements are not understood during the production process, which leads to quality loss. These problems can be listed for external source control. This requires marketers to fully understand the customer's product characteristics and ingredients, packaging quality requirements, packaging process, etc. and make written records during the process of communicating with the customer. When the production task is issued, the customer's requirements are attached, so that the technology department can By reviewing the materials and structure, the personnel of the production department can truly understand the customer's requirements, and when performing quality management, can they focus on the quality tracking according to customer requirements, so as to effectively prevent quality problems.
2.Quality loss caused by the production process
The production process of most companies that make plastic flexible packaging is "printing-compositing-cutting-bag making". In the previous production quality management, understand what causes the largest quality loss in each process, find out the key control points according to the reasons, and formulate the operation and inspection standards for the key control points. During production, aim at the target; The three-layer quality control system consisting of inspection, workshop director supervision and quality inspection, can effectively control the occurrence of solvent residues and other quality problems.
The second step: the first article confirmation and each volume signing system
According to the production process, the first item is confirmed according to the process, and the quality of the semi-finished product or bag-making product is rolled each time. We formulate the first confirmation item form for printing, compounding, slitting, and bag making in the management production process, and proceed item by item. Each time you roll down, you need to sample to find the problem and improve it. For example, printing, proofing with waste materials, first review the color, if the color is accurate, change the material to print 5OOm, change the roll and sample for the first confirmation, check the color, text, pattern, size, overall printing effect, solvent residue, etc Quality issues. Improving in time if there are problems, and mass production without problems. In this process, each roll of material needs to be sampled to review the quality when the next roll is rolled. It also needs to implement a three-layer quality consisting of the captain's self-inspection, workshop director supervision and quality inspection Check the system so that quality problems can be effectively controlled. Even if there is a quality problem, the amount of loss will not be large, and it will not be scrapped in half or in batches.
Step 3: Material balance and traceability in the production process
Keep the materials in the production process in a controlled state, and the input materials are equal to the finished product or semi-product. Plastic flexible packaging must be managed according to the order, picking according to the order, and arranging production to the machine and person according to the order. During the production of each production link, the volume number, weight and length, time, and operator need to be recorded each time the next roll is rolled. The material balance of the process, if there is imbalance, you can find and analyze the cause, and also achieve traceability of the product.
Step 4: Training based on problem points
Train according to the problems in the above three steps. Improve the performance of production operators, so that a stable and continuous production process is formed.
