Precision stamping parts technology is a forming process technology that relies on stamping equipment and dies to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain the required shape and size of the workpiece. The precision in precision metal stamping mainly refers to the high precision of the mold, the high precision of the stamping machine, the high precision of the testing equipment, and the high precision of the final product. The output of precision stamping products is gradually increasing.
In recent years, the output of precision stamping parts has been increasing year by year, and the development is very rapid. Precision stamping parts technology has huge advantages in automotive engines and other fields, and has become an indispensable metal die casting technology in these fields. These advantages have been applied to the IT industry. Precision stamping parts technology has the characteristics of multiple varieties, material diversity, thin plate coils, large automated production batches, high precision, complex shapes, high technical content and high added value. In today's highly developed market economy, it has a very important position.
Precision stamping parts technology can not only manufacture small instrument parts, but also large parts such as automobile beams and pressure vessel heads; it can manufacture parts of general size grades and shapes, but also parts of precise and complex shapes. The outstanding features of stamping products, especially precision stamping products are:
1. The consistency of product quality is required, that is, the quality of all products of the same model is highly consistent, and all products of the same model are completely interchangeable;
2. Assembly suitability, that is, all parts must achieve a perfect fit with other various parts in assembly, especially the precision parts of high-precision electromechanical equipment, the required dimensional error is very strict;
3. Production efficiency, that is, compared with other metal forming processes such as casting and forging, precision stamping parts technology has obvious advantages in production efficiency.
China has now become the world's manufacturing center. In the past ten years, rapid development has been achieved in industries such as automobiles, communication electronics, and household appliances, which has led to rapid growth in the demand for metal stamping parts. Many multinational companies have transferred the manufacturing of complete machines to China, and at the same time they have also transferred supporting factories to China. The purchase of domestic accessories has also increased rapidly year by year, which has driven the rapid development of domestic related industries. In this context, the metal stamping industry, one of the basic manufacturing industries, has also achieved rapid development.
China’s precision stamping parts technology enterprises are mainly divided into two categories. The first category is a closed single supporting enterprise, which is mainly a stamping enterprise or factory that provides professional support for large-scale machine manufacturers, and mainly foreign-invested enterprises. Machine products supporting the production of parts and components, such enterprises generally do not participate in the market share competition outside the target machine plant, and their production capacity cannot be fully utilized. The second category is independent metal stamping companies, including specialized metal stamping parts manufacturers and small-scale stamping companies.
The development of precision stamping parts technology has a great effect on improving the production quality of related products and improving the technical level of the industry. Precision stamping parts technology will continue to develop towards a higher level, higher requirements, and higher standards.
