Mould is an important process equipment for forming various industrial products, and a means of forming blanks or parts in mechanical manufacturing industry. It plays an important role in modern industrial production, mainly in the following aspects.
(1) Technology of moulding products is widely used. For example: die forgings, stamping parts, extrusion and drawing parts are all plastic deformation and forming of metal materials in mould; die castings and powder metallurgy parts are also filled and pressed in mould; plastic, ceramics and other non-metallic materials products are mostly processed and formed by mould.
(2) Mould forming parts can be processed with less and no cutting. Less and no cutting is a direction of development of mechanical manufacturing. Mould forming is the way to achieve less and no cutting technology, and improvement of level of mould manufacturing is key to achieve less and no cutting. Improvement of die manufacturing level can improve precision of moulded products and reduce roughness value, so it is possible to directly process finished products without further finishing, thus avoiding cutting.
(3) Mold forming has characteristics of high quality, high yield, low consumption and low cost, so it has a wide range of applications. According to relevant statistics, various parts and components manufactured by moulds account for 60%-70% in fields of airplanes, automobiles, electrical appliances and meters, more than 80% in household appliances, and 85% in light industrial products such as watches and bicycles.
Development of modern industrial products and improvement of technological level largely depend on development level of mould industry, so mould industry will play an increasingly important role in the development of national economy and society. Weakness of mould industry will seriously affect change of industrial product shape and development of new products. Level of mould manufacturing and quality of die play a decisive role in accuracy, margin, productivity, cost and utilization of advanced equipment.
