The raw materials of casters are particularly important to the production of caster company's products, and it is the basis to ensure the quality of caster company's products. As everyone knows, with the increasingly fierce caster market demand, there will always be some manufacturers or illegal merchants who are only profitable and will bring counterfeit and inferior caster products to the market. Even some reliable manufacturers, because of their own management method system loopholes or other reasons, may also be possible. Make some fake and shoddy goods flow to the sales market. In the whole process of manufacturing and application of such fake and inferior products, they constitute a major quality or safety risk, and become the culprit of product manufacturing safety accidents or safety production accidents. In addition, if the adjustment of the purchased raw materials is unreasonable, it will also affect the quality of commodity production and processing. How to prevent fake, inferior or moldy raw materials from being injected into the production line is a subject that every company must analyze. Authoritative experts believe that caster companies must adjust the quality of the company’s raw materials to ensure the quality and safety of equipment production and processing. They must review and select from raw material suppliers, improve the engineering acceptance before raw materials enter the warehouse, and improve the quality of logistics and warehousing management. Field to achieve manipulation. How to ensure the quality of caster materials?
One. Classification of raw materials and comments and selection of suppliers
1. The production of raw materials should be managed in groups, highlighting themes
The caster company must have various types of raw materials, but different raw materials have different hazards to the quality of the products produced and processed. In order to facilitate the implementation of key manipulations of purchase quality, the raw materials should be managed in groups according to the degree of harm the raw materials have to the quality of commodity production and processing products. Generally divided into three categories:
A-type raw materials: refers to the raw materials that are likely to cause immediate and serious harm to the quality of the production and processing of the product (such as the important role of the product, the characteristics are likely to cause immediate harm) in the entire process of manufacturing and application.
Class B raw materials: refers to raw materials that are likely to cause indirect or critical hazards to product quality during the entire manufacturing and application process.
C-type raw materials: refer to raw materials that are generally auxiliary parts that are generally or mildly harmful to product quality.
2. Comments on raw material suppliers
Practical activities show that whether the quality of the purchased raw materials is stable depends to a large extent on the supplier’s product quality management capabilities. Therefore, the quality assurance level of various raw material suppliers should be evaluated before purchase.
(1) Comments on suppliers of Class A raw materials
Judging the suppliers of Class A raw materials is the key. Generally speaking, it is necessary to visit and review the quality management system operation status, past supply status, the ability to handle and rectify the abnormal supply quality, as well as the delivery on time and the total number of deliveries. Ability, the cost-effectiveness of its products, and its after-sales maintenance service capabilities (including after-sales maintenance service mentality, timeliness, and actual effects), etc. At the same time, it should also be based on: check the materials given by the supplier, conduct side-by-side investigation and mastery from other consumers of the supplier, carry out testing and use of the raw material samples supplied, and complete the results of the timely analysis of the quality of the raw materials. Reviews.
(2) Comments on B and C raw material suppliers.
generally do not visit and inspect, the key is to check the materials given by the supplier, test and use the raw material samples supplied, analyze the results of the raw material quality on time, etc., to achieve the goal of commenting on the supplier. Among them: For comments on B-type raw material suppliers, the procurement unit clearly proposes the "B-type raw material supplier review roster" and relevant materials for B-type suppliers, or the quality and service items such as past B-type raw material testing and application status Material and information content such as price, price, etc., submitted to relevant departments such as technology, manufacturing, quality, accounting, etc. for countersigning (review), and reporting to high-level residential management for permission; comments on the working ability of the C-type raw material suppliers shall be clearly proposed by the procurement unit The "C-type supplier review roster" will be implemented after being countersigned by the quality, accounting, etc., and signed by the head of the purchasing department.
3. Selection and clarification of raw material suppliers
Qualified raw material suppliers should be clarified based on selection. Obtaining a qualified raw material supplier is based on the above conclusions of the evaluation of each supplier's quality assurance ability and its production and application status, price, reputation and other factors. Therefore, in the end, the supplier is clarified, and as many suppliers as possible with the same raw materials are selected for comparison, especially when the manufacturing application status and the quality assurance ability of each supplier are basically abnormal.
Two. Strict raw materials entering the factory control
Purchasing raw materials from qualified suppliers is not everything going well. A qualified supplier only means that the supplier has the main standard for giving relatively stable quality raw materials. Whether the total number of raw materials delivered by the supplier is in short supply and whether the quality can meet the manufacturing regulations is not beyond doubt. Therefore, before the raw materials enter the factory, the incoming quality control should be strictly controlled in accordance with the following regulations.
Engineering acceptance of raw materials that do not need to be tested. The project acceptance shall be based on the raw material supply contract, the "Qualification Certificate", "Material Book" and other quality certification documents of the same industry; for some low-value and easy-to-consume, the corresponding "Qualification Certificate" and "Material Book" cannot be presented. , Be sure to supply the test product early. For raw materials without "Certificate of Conformity" and "Material Book", engineering acceptance and storage shall be rejected.
