Machinery manufacturing, metal stamping market development
Metal stamping on punching and stamping die exert force on materials such as sheet, strip, to produce plastic deformation or separation, to obtain the required shape and size of workpiece forming method.
According to the classification, can be divided into separation process and forming process two kinds big.
Separation process is also called the blanking, and its purpose is to make from the sheet metal stamping parts along the contour line must be separated, and at the same time guarantee the quality requirements of the separation section.
Forming process is designed to make sheet metal under the condition of not to break the billet occurred plastic deformation, made into the required shape and size of the workpiece.
Cutting, bending, shear, deep drawing, bulging, spinning, correction is several main metal stamping process.
In the actual production, is often a variety of process integrated applied to an artifact.
Metal stamping industry is an important divisions in metal forming industry, is the basis of the mechanical manufacturing industry, its development degree reflect the manufacturing technology of a country's competitiveness.
Car body, chassis, fuel tank, radiator fin, the boiler steam drum, container shell, motor, electric iron core silicon steel sheet, apparatus and meters, household appliances, bicycles, office machinery, household utensils, and other products of manufacturing both need a great deal of metal stamping parts, involved in aerospace industry, automobile manufacturing, electronic appliances, instruments and meters industry, equipment manufacturing industry, and many other aspects, use range is very wide.
Especially in recent years, China automotive, communications, electronics and the rapid development of household electrical appliances and other industries, making metal stamping, the rapid growing demand and other components.
Many multinational companies in the manufacture of the machine transfer to China at the same time, will also be supporting factories moved to China, demand and accessories purchase quantity increase year by year, led to the rapid development of domestic related industries.
In this context, as a foundation for manufacturing industry, one of China's metal stamping industry has gained rapid development.
Rapid growth of market capacity, the current domestic metal stamping industry enterprise quantity, small scale, industry concentration degree is low, the informationization level and low level of technology, product quality level is low, many market participants and market competition fully, so the selection of metal stamping factory is crucial one annulus.
Precision metal stamping parts custom technology has 30 years, are good at stamping production precision automotive connector terminals, relay terminal, terminal, shrapnel, etc.
