Precautions for the use of raw materials

for the sake of cost control or the development of new businesses, it is inevitable that printing enterprises often encounter problems in the testing and use of raw materials. There are many aspects that need attention here, which are briefly described below


for new businesses, we need to choose new raw materials. At this time, the choice of raw materials is very particular. First, the products delivered to customers need to meet the use requirements, and in addition, we need to calculate the cost to ensure the profit margin. We should mainly do: ① select raw materials according to the data of product performance required by customers and analyze the relevant data of various raw materials. This selection standard is practicality and applicability; ② After selecting raw materials according to the new products developed, appropriate production processes should be formulated and the utilization rates of raw materials such as paper utilization rate and layout utilization rate should be designed, and then put into practice in actual production

2 detection

when raw materials are used, it is imperative to detect raw materials. This detection should follow the standards and methods jointly agreed by the supplier and the demander based on national and industrial standards. In addition, it needs to be clear that the raw material testing should focus on the manufacturer, that is, move the testing to the production link, focus on the process inspection, supplemented by the final inspection, so as to ensure that the raw materials produced meet the customer's use requirements, because when the demander tests and verifies that the raw materials are unqualified, it will cause great losses to both parties at the same time. Now the supply and demand sides should follow the mutually beneficial and win-win relationship, Therefore, when the test is moved to the production link of the manufacturer, the quality of raw materials and products can be guaranteed to be stable and qualified to the greatest extent. Although the testing is mainly conducted by the supplier, it does not mean that the demander does not test. At this time, the demander's testing is mainly to test and verify the relevant performance of the raw materials provided by the supplier's customers in addition to the specific product requirements of Nangang. In addition, the demander should find out the relevant raw material data according to the actual use and feed back to the supplier, so that the raw materials can be continuously improved, In order to better serve the production and final product use

3 speed up the evaluation of the lack of competitive capacity exit suppliers

when selecting new raw materials, we should also follow a principle, that is, to evaluate the relevant suppliers. This evaluation should not only check the business license and business status of the enterprise, but also include the supply status and use of the raw materials in the industry, and then use these materials as an important basis for the selection of raw materials. The situation of large enterprises is relatively easy to judge, while those smaller enterprises have certain difficulties in judging. At this time, we should add soft and hard strength indicators such as enterprise reputation, supply cycle and long-term development status to the evaluation criteria

4 initial trial

when the supplier and raw materials have confirmed the selection, the selected raw materials should be tried. In order to avoid losses between the supplier and the demander, the trial should also start from a small batch trial. This initial test of raw materials should have a certain purpose, mainly including observing and inspecting whether the properties of raw materials are consistent with those embodied in the actual production, and confirming the product ink color, specification, etc. in the actual production. In addition, a series of relevant tests should be carried out for the produced products in order to have a certain perceptual understanding of the requirements of the end product users, so as to provide customers with qualified final products

it is popular to meet two standards at the same time

5 pilot test

when raw materials pass the preliminary test, it does not mean that raw materials can be put into formal production and use, because there is another barrier after the preliminary test and before batch use, that is, the pilot test of raw materials. In addition to continuing to verify the relevant test items of the preliminary test, the pilot test should also send the produced final products to users for trial, Then, according to the feedback from users, and with reference to the performance of raw materials, production processes, etc., put forward corresponding improvement suggestions for raw materials, and continue to carry out corresponding tests in the future. In addition, there is another work, that is, cost analysis for the pilot test, in order to judge the comprehensive cost value of the application of such raw materials

6 feedback on the use of batch raw materials

when the raw materials have passed the pilot test, they can be used in batch. However, because the raw materials that have passed the pilot test will inevitably have one or another problems in mass production, use and use of the final products at the client, it is also necessary to track the raw materials that are supplied in batch. It mainly includes the comparative testing with reference to the raw material testing data during the pilot test, the use status of the production process, the comprehensive cost comparative analysis with reference to the use of mature raw materials used in the past, the use of the final product at the client and the user's requirements for the product, and other data and information, and then put forward corresponding improvement suggestions to the raw material suppliers and continue to track in the future use, Until the raw material supplier becomes a qualified supplier, it should be noted that after becoming a qualified supplier, it only changes the tracking inspection of each batch into random inspection, not canceling the inspection of raw materials

7 tracking the market for continuous improvement

it is not complete that raw materials are made into final products and recognized by customers, because packaging and printing enterprises belong to the service category in the whole product manufacturing process, and shoulder the requirements of ensuring that the packaging appearance is exquisite and meets the relevant strength requirements. In order to achieve the recognition of customers, end consumers and other relevant audiences, packaging and printing enterprises should also track the reflection of final products in the market, so as to determine the status of packaging products, and then put forward corresponding improvement suggestions for raw materials based on the feedback information of packaging product users, and continue to track in the subsequent production and use, so as to achieve the purpose of continuous improvement until the final audience is satisfied

8 evaluate the quality status of raw material suppliers with long-term supply

establish evaluation criteria for qualified raw material suppliers with long-term supply. The evaluation criteria should include: whether the relevant data of raw materials fluctuate within a certain period of time, the use efficiency in actual production, the qualified product rate, quality status and other data completion status, whether the supply cycle is in place, and whether the after-sales service is timely, Whether the improvement measures meet the standards and whether the price (mainly based on the comprehensive cost in actual production) is reasonable. After that, we will conduct a comprehensive evaluation of these projects, and then score and grade raw material suppliers, which will be referred to in the future continuous procurement, so as to introduce a competitive mechanism into raw material suppliers, so that raw material suppliers have a sense of urgency, so as to restrict raw material suppliers to provide more suitable raw materials in all aspects to a certain extent

the selection and use of raw materials occupy a very important position in the development of an enterprise, and the selection of the best raw materials (the best comprehensive performance in terms of cost performance and credibility) plays a decisive role in all aspects of the development of the enterprise. Therefore, enterprises should put the selection and use of raw materials on a strategic level, and this selection standard should be derived from practice, used in practice, and follow the principle of not choosing the best Choose only the most appropriate principle
