| Manufacture Industry: Analysis for Hardware Stamping Industry |
| Time：2016-11-21 Hits：6414 |
| The hardware stamping refers to the processing method for gaining the required shape and dimension work pieces by exerting external force on materials, such as plate and belt with punch and stamping dies and then making plastic deformation or separation. In consideration of technology, it can be divided into separation and forming process. The separation process, also called blanking, is aimed to separate hardware stamping parts from plates along certain contour line under the premise of meeting the requirements for quality of separation section. The forming process is aimed at plastic deformation on the basis of not destroying plate so as to form required shape and dimension. The blanking, bending, cutting, drawing, expansion, spinning and correction are main hardware stamping technologies. In actual production, several processes are often used for the same work piece integrally. Since the hardware stamping industry is an important branch in metal forming & processing industry and also the basic industry of mechanical manufacture industry, its development can reflect the manufacture process and technology competitiveness of a country. The products, such as automobile body, chassis, fuel tank, radiator fin, boiler steam drum, vessel shell, motor, iron-core silicon steel sheet of electric appliance, instrument, household appliance, bicycle, office machinery and daily use utensils are produced and manufactured with numerous hardware stamping parts, which are also applicable to aerospace industry, automobile manufacture, electronic & electrical, instrument and equipment manufacture industry widely. In recent years, China has become a world’s manufacturing industry center and a consumer power, which enables China to attract the world’s attention; in particular, the quick development of automobile, communication electronics and household appliances has stimulated the demand of such parts as metal stamping spare parts. While transferring the complete machine manufacture to China, many transnational enterprises also transfer the matching factories to China and purchase more and more accessories from China year by year, which drives the fast development of relevant domestic industries. Under the background, China’s hardware stamping industry, one of the basic sub-industries of manufacturing industry, develops quickly. China's hardware stamping industry has gained a fast growing marketing volume, featured by numerous enterprises involved, small scale, low industrial concentration, low informatization and technical level, quite low product quality grade, multitudinous market participants and sufficient market competition. |
