Raw materials for metal hose metal hose production enterprises is essential is to ensure product quality metal hose basis. However, with the metal hose increasingly fierce market competition, there are always some unscrupulous mercenary manufacturers or vendors, will be inferior metal hose products to the market, even if some of the regular factory, due to loopholes in their management or other reasons, may also make Some low-quality products into the market. The use of inferior products in the production process, constitute a major quality or safety problems, as the product quality accidents or safety incidents culprit. In addition, the procurement of raw materials back if not properly controlled, but also directly affect the quality of products. How to prevent shoddy or deterioration of the raw materials into the production line is every business needs study. Experts believe that the metal hose to control the business enterprise procurement of quality raw materials to ensure product quality and safety needs from raw material supplier evaluation, selection, storage of raw materials prior to acceptance to strengthen and improve the quality of other aspects of warehouse management to control .
First, the raw material classification and evaluation and selection of suppliers
1. Production of raw materials should be of category management, focused
Metal hose companies need a wide variety of raw materials, but different material impact on the quality of different products. In order to facilitate the procurement of quality key control, should be the quality of raw material production impact of different classification of raw materials management. Generally fall into three categories:
A class of materials: means to use in the production process, product quality may be a direct, significant impact (for example, the product key features, performance may have a direct impact) of the raw materials.
Class B material: refers to the use in the production process, may be brought to the product quality or indirectly affect the more important raw materials.
C Class materials: refers to the general as auxiliary parts, the general impact on product quality or minor raw materials.
Practice shows that the quality is stable procurement of raw materials, largely depends on the level of supplier quality management. Therefore, purchasing the former should provide all kinds of raw material suppliers to evaluate the quality assurance capabilities.
2. On the choice of suppliers of raw materials and to determine
Qualified suppliers of raw materials should be determined by choice. To obtain a qualified raw material suppliers, it depends on the ability of the supplier quality assurance results of the evaluation and production use, price, reputation, and other factors. Finally, therefore, identify suppliers, should be more appropriate choice of several suppliers of raw materials, the same comparison, especially in the production and use of quality assurance of the ability of suppliers almost the case.
Second, strict control of raw materials into the plant
From the evaluation of qualified suppliers of raw materials, not to all is well. Suppliers qualified, only that the vendor capable of providing relatively stable quality of the basic conditions for raw materials, the actual number of the arrival of the existence of a shortage of raw materials, quality, whether it can meet production requirements, but not sure. Therefore, the raw materials before entering the factory, should be strictly in accordance with the following requirements well into the plant quality.
1. No need to test the acceptance of raw materials. Contract should be based on purchase of raw materials, accompanied with the goods "certification", "book material" such as the quality of evidence and acceptance; consumables and difficult issue of the appropriate individual "certificate", "book material" and must be available in advance samples. Of no "certification", "material book" of raw materials, should be refused acceptance, storage.
2. On the need to test the raw materials have passed the test before storage. Storage of raw materials to be tested before purchasing department should fill out the "inspection records" to pay professional inspection department, issued by a qualified professional inspection department inspection report, the report by a qualified storage. If the test failed, you should do a good job "unqualified record" one of the fill, and fill in the quality of information feedback in time one-way feedback on the quality of the competent authorities to require the purchasing department for return procedures.
3. The timely establishment of the acceptance inspection acceptance records storage. Custodians should establish a "raw material storage inspection records", records include: Name of raw materials, specifications, models, manufacturers, the arrival time, arrival quantity, the number of qualified, acceptance of time and the corresponding quality certificate; according to material type, name , specifications were registered account the cards, to prepare for future inquiries, confirmed.
4. Urgently or quality of evidence and acceptance of raw materials is not the whole deal. Urgently or quality of evidence is not all raw materials, the need for timely feedback on the quality of fill in the information department in charge of one-way feedback on the quality, the quality department to the purchasing department bombarded with evidence not yet reached the quality and storage of this material inspection procedure by temporarily storage area failed to verify the process only after passing inspection procedures.
5. Materials, surface quality inspection to check the availability of raw materials, packaging material damage, defect, to see whether the packaging of corrosion, leakage, check out of the box name, grade, specifications, etc., with the product certificate, packing list and inspection .
6. On stage only in order to install and use the intrinsic quality of exposed, raw materials, the quality of tracking card custodian to establish and maintain communication with the production and use of units, first hand, do identify problems and timely feedback, and notify the supply department according to regulations.
Third, strict quality control of raw materials storage
Storage of raw materials to prevent deterioration, the control of raw materials to continue the procurement process, the key to do well as management.
1. On the storage of raw materials management. Of class A stock of raw materials, especially raw materials, should always be checked, so that "ten no", that is, no wave, no rot, stainless steel, not mold, not bad, the same, not bad, ice-free, no loss, no borers.
2. Treasury management of the environment. Warehouse shelves, items should be placed in reasonable unobstructed aisle, no broken windows and doors, so that the "three net" (floor, windows, shelves), no debris, garbage, dust.
3. Stacking and covered storage of raw materials. Stacking and also ensure that libraries have covered an important aspect of quality of raw materials. Inventory of raw materials must be based on its performance, storage, stacking and covering a reasonable request. A class of special consideration to the performance of raw materials, packaging, quality, and storage conditions on the ground, the stacking method appropriate to achieve flood control, moisture-proof purposes.
4. Raw materials inspection. Raw materials into the warehouse, in the acceptance, stacking the same time, according to the classification of raw materials and maintenance requirements for maintenance of control, that should be regular or frequent inspection and remove, deal with hidden dangers.
5. The raw material out of library management. Shall comply with "first in first out" principle, in particular, deal with storage of long goods heap big concern is difficult to check the raw materials, raw materials to a library of such a timely manner. At the same time, regulate the storage process behavior, the quality of raw materials during transport to avoid damage.
Fourth, regular analysis of the quality of raw material procurement
Regular analysis of the quality of raw material procurement is easy to overlook the many metal hose companies, but very important aspects. On the regular analysis of the quality of raw material procurement, we can find quality suppliers of raw materials supply is a regular in the stability, but also for the next step after the production process quality control and selection of suppliers, adjust, and provide important information and even basis.
Regular analysis of the quality of raw material procurement, A class of materials generally should be a month; B class of materials once every six months; C class should be a year of raw materials. Analysis of the contents are: raw materials, test, testing, inspection results of the statistical analysis; suppliers and delivery when the number of scheduled delivery; supplier quality and the exception handling and rectification of such.
In short, the metal hose enterprises not only pay attention to the production process, attention to effective, should be concerned about the quality of raw material procurement. Procurement of raw materials to do quality management, and strengthen quality control of the procurement process, metal hose companies have a solid foundation of product quality and reliability assurance.
