Application of ISO9001:2008 in the production process of steel drum
Guan Yuqin
The specific application of ISO9001:2008 in the production process of steel drums is mainly reflected in the following aspects:
1. Customer requirements for products
It is the customer-related process in the standard. First of all, the sales department and the technical department should promptly understand the customer's requirements for the product. In terms of performance, such as the compatibility of the materials and sealant, the compatibility with the sealing ring of the barrel, and the degree of cleanliness in the barrel, The spray coating is a common chemical coating or a food grade or acid and alkali resistant coating. Whether galvanizing and steel barrel strength are required, etc., and then a processing plan is formulated. If there are special requirements, a contract review should be conducted.
2, procurement
For steel drum manufacturers, the raw and auxiliary materials purchased mainly include steel plates, barrels, sealants and coatings. The supplier must first confirm the purchase. For enterprises that have been producing steel drums for many years, the purchase of raw and auxiliary materials is passed. The use of existing basic fixed suppliers, the main aspects of confirmation are supply capacity, product quality, price, transportation capacity, after-sales service, etc., should be assessed once a year, shop around, in principle, the same product can not be only one Supply by the supplier, first, the price and quality can not be compared, and second, there is only a single supplier. If the supplier cannot supply the goods in time for some reasons, it will affect the normal production of the steel drum production enterprises. The assessment of the supplier can also be carried out on-site for on-site assessment. The supplier's production process, equipment operation, management status, and use of raw materials can be seen to judge the supplier's supply guarantee capability. After the qualified supplier determines the purchase, The incoming product should be inspected:
(1) Inspection of steel plate: Firstly, the supplier shall provide the qualified status mark and material list of the steel plate, then the quantity and the inspection of the outer packaging, and the items such as the appearance quality, sheet thickness, unevenness and sickle bend of the steel plate shall be unrolled. Inspection, and each item must be inspected before use. For the various trace elements and annealing conditions provided in the material list, because the steel drum manufacturer does not have the inspection capability, it generally does not carry out the inspection items of the purchase. Only in the spot welding and seam welding, if the sheet material is too hard and the steel plate is too elastic When the edge of the edge is cracked and the bottom cover is cracked during the stretching process, the material of the plate is inspected, but at this time, the non-conforming product has been produced. This inspection has yet to be resolved in the management of the enterprise.
(2) Inspection of the barrel mouth piece, the first is the size, followed by the interchangeability, the quality of the galvanized layer, the meshing condition of the thread, whether there is a crack after the lock, and whether the welding quality can withstand the strength of the wrench. It is a random inspection and is inspected according to the provisions of GB2828. Then there is whether the sealing ring is rubber or plastic, depending on the needs of the customer and whether the contents contained are compatible.
(3) Sealant and paint: The viscosity should be checked. It can be measured with 4 cups, then the appearance quality such as color, precipitation, suspension, production date, qualified mark and matching thinner.
3, the realization of the product
Steel drum production equipment is generally special equipment. The operation documents guiding the on-site production are important information describing the characteristics of the product. During the production process, seam welding and coating are the key processes, and separate work documents and inspection records are required. Competence and qualifications are subject to accreditation.
4. Inspection during production process
(1) Inspection of the size of the blank
Mainly the size of the barrel, especially the size of the diagonal can not exceed the error.
(2) Inspection of welds
At present, the welding machine of steel drum production enterprise is very advanced, and the barrel, spot welding and seam welding are integrated. The welding quality is high, and the welding quality can be guaranteed. In the past, the airtight inspection after straight seam welding has been basically cancelled.
(3) Inspection of the edge, the rib and the pressure ripple
Mainly the dimension of the edge, whether it is the extrusion edge, the spinning edge should monitor the size of the edge and the uniformity of the circumference and the angle of the edge, which directly affect the quality of the seal.
(4) bottom cover stretching
There are items such as stretching depth, edge burrs, wrinkles, and cracking.
(5) Locking and pressing of the mouthpiece
The height after the lock and the pressure test on the mouthpiece.
(6) Inspection of sealing process
The sealing process is an important process. For the height, width, shoulder depth, total length of the barrel, and the quality of the roll, the appearance of the steel drum should be inspected. This process is a key process.
(7) Airtight test
The airtight test is a mandatory inspection process for one of the production processes, and only the inspection is performed.
In short, ISO9001:2008 is very suitable for steel drum manufacturers, the quality of management has improved, and the quality of products has increased accordingly.
