With the development of the hardware product industry, hardware stamping equipment and technology are constantly improving. Hardware stamping parts are becoming more and more precise, with more and more types, and the market size is constantly expanding. Precision hardware stamping parts can be divided into various types based on industry, usage, and process characteristics. Below is a brief introduction to the types of precision hardware stamping parts:

1. Automotive parts: mainly including automotive structural parts, automotive functional parts, automotive lathe parts, automotive relays, etc.

2. Electronic parts category: mainly including connecting devices, connectors, brush parts, electrical terminals, elastic parts, etc.

3. Household appliance parts: mainly including household appliance parts, such as color tube electronic gun parts, as well as small household appliance parts, various structural and functional parts, etc.

4. IC integrated circuit lead frame: mainly including discrete device lead frames and integrated circuit lead frames.

5. Motor core: mainly includes single-phase series excitation motor core, single-phase household motor core, single-phase shaded pole motor core, permanent magnet DC motor core, industrial motor core, plastic sealed stator core, etc.

6. Electrical core: mainly including E-shaped transformer core, EI shaped transformer core, I-shaped transformer core, and other transformer iron chips.

7. Heat exchanger fins: mainly including industrial heat exchanger fins, household heat exchanger fins, automotive heat exchanger fins, etc.

8. Other types of parts: mainly including instrument and meter parts, IT parts, acoustic and camera parts, modern office parts, and daily hardware parts.

The above content is about the classification of precision metal stamping parts. Precision metal stamping parts have the characteristics of rich variety, material diversity, large automated production batches, high accuracy, complex shapes, high technical content and added value. However, the production of precision stamping parts usually requires the use of specialized stamping and stretching oil to meet process requirements.
