Precision metal stamping die

An Overview of Stamping Mold Industry

Mold is the basic technology equipment that uses large, influence widely in manufacturing industry, be known as "mother of industry", "crown industry", is high-tech intensive industry.

Stamping die-In cold stamping process, a special process equipment for processing materials(metal or non-metal) into parts(or semi-finished products), called cold stamping die(commonly known as cold stamping die). Stamping-is a pressure processing method at room temperature that uses a mold mounted on a pressure machine to exert pressure on the material to separate or plastic deformation to obtain the required parts.

Stamping die is an indispensable process equipment for stamping production and is a technology-intensive product. The quality, production efficiency and production cost of the stamping parts are directly related to the mold design and manufacturing. The level of die design and manufacturing technology is one of the important indicators to measure the level of product manufacturing in a country. It determines the quality, efficiency and development ability of new products to a large extent. At present, it is possible to produce multi-position step input modules with a step accuracy and a forming accuracy of about 2 μm.

An Overview of Small Precision Hardware High Speed Continuous Stamping Mold

Small precision hardware continuous dies belong to the high-end die industry, which has the characteristics of complex structure, high machining accuracy, fast stamping speed and long service life. Small hardware high-speed continuous stamping die is widely used in the electronics industry, and it is also the most important tool for the development and production of new product structures such as mobile phones and other mobile communication terminals. In the "Eleventh Five-Year Plan" of the mold industry, precision stamping dies, especially small precision hardware high-speed continuous stamping dies that are closely related to the electronic information industry, have been listed as priorities for development. To produce high precision and high stability stamping parts, the technical level of stamping die must be improved. With the development of Microelectronics technology, the integration of consumer terminals such as mobile phones and digital products has become more and more high, while its size and weight have declined in the masters, requiring its internal components to become smaller and smaller. For example, Connectors supporting mobile phones and digital products have also developed into ultra-miniaturization and thinness. The lead spacing of connectors has been reduced to 0.5 mm, 0.4 mm, and 0.3 mm, which also promotes the development of precision mold technology.

Market Status of High Speed Stamping Mold for Small Precision Hardware

The multi-position step die and precision die represent the development direction, accuracy and life requirements of the small precision hardware high-speed continuous stamping die, mainly for the electronic information industry. These two kinds of molds, domestic already have quite foundation, and have introduced foreign technology and equipment, individual enterprise production product already reached the world level, but most enterprises still have big gap, the total quantity also exceeds demand. At present, it is possible to produce multi-position step input modules with a step accuracy and a forming accuracy of about 2 μm. Foxconn, Taike, Changying Precision and other companies rank among the top three in the world in terms of the development of small precision metal molds. Among them, Changying Precision is an excellent representative of local companies and has made rapid progress in mold development. In 2009, the development of small precision hardware high-speed continuous stamping molds reached 1800 units.

Development Direction of High Speed Continuous Stamping Mold for Small Precision Hardware

The key points of mould technology and mould industry development are: improving precision, scale development, innovative structure design, and refined management. Meeting this requirement requires urgent development as follows:

(1) vigorously training the talents of mould design and processing;

(2) vigorously improve the level of domestic mold processing equipment;

(3) vigorously improve the quality of domestic mold materials;

(4) Support enterprises with a good domestic mold base, and gradually produce a number of leading die enterprises that are close to the international level.

Application of Small Precision Hardware High Speed Continuous Stamping Mould in Precision Electronic Components

As an important part of the electronic information industry, precision electronic components are widely used in mobile communication terminals and digital electronic products. Mobile communication terminals and digital products have the characteristics of fast upgrading, multiple product types, and small product sizes. Precision component products also require new products in many types, various forms, short development and delivery cycles, and high accuracy. Precision hardware components are generally assembled from multiple hardware parts. To produce high-precision hardware parts in large quantities and rapidly, they must be completed using a small precision hardware high-speed continuous stamping die. Because the small precision hardware high-speed continuous mold has the following advantages: 1. The speed of stamping, the high production efficiency, the number of stamping times per minute can reach more than 300 times, which is more suitable for the production of large quantities and urgent delivery products. 2. The degree of automation is high, and a set of molds can be combined with a variety of impulse pressing processes, such as the following materials, stretching, sprouting, etc., which are more suitable for products with complex production structures. 3. The precision of the punch product is high, because the precision of the high-speed continuous mold processing of small precision hardware can reach 2um, and the precision of the punch hardware parts can reach ± 0.02 mm. Therefore, the development level and open modulus of a small precision hardware high-speed continuous stamping die of an enterprise determine the manufacturing level of the enterprise's precision electronic components. The domestic domestic company Changying Precision has a high level of development of its small precision hardware high-speed continuous stamping die. In 2004, he took the lead in developing mobile communication terminals and digital product precision connectors; In 2007, microRF connectors for mobile communication terminals and digital products were developed and pioneered the serialization of connectors for mobile communication terminals and digital products.
