The processing methods for small hardware include cold pier processing, stamping processing, continuous die precision forging processing, CNC machining, powder metallurgy processing, etc. Cold pier processing speed is fast, precision is not high, stamping processing accuracy is high, speed is fast, and only flat bending can be processed. Continuous die precision forging processing speed is fast, precision is high, and three-dimensional structural parts can be processed with high energy. CNC machining accuracy is high, speed is slow, and powder metallurgy processing accuracy is not high, speed is fast, and strength is not high.

Surface processing of hardware parts:

1. Spray painting processing: Hardware factories use spray painting processing when producing large hardware products, to prevent rusting of hardware components, such as daily necessities, electrical enclosures, handicrafts, etc

2. Electroplating: Electroplating is also the most common processing process in hardware processing. Modern process technology is used to electroplate the surface of hardware components to ensure that products do not undergo mold or embroidery after long-term use. Common electroplating processes include screws, stamping parts, battery cells, car parts, small accessories, etc,

3. Surface polishing processing: Surface polishing processing is generally used for a long time in daily necessities. For example, if we produce a comb, which is a hardware component made by stamping, the edges and corners of the comb are very sharp. We need to polish the sharp parts of the edges and corners to create a smooth face, so as not to cause harm to the human body during use.

Turning the outer circular surface is the basic method of machining the outer circular surface in hardware processing, and the equipment used is a lathe. In general machinery factories, lathes account for about 40% of the total number of machine tools. Turning is the main method for rough and semi precision machining of various materials' cylindrical surfaces, and it is also the final finishing method for various materials that are not suitable for grinding.
