In order to have better flatness requirements, shear and other tests can usually be performed when selecting self-piercing rivets.

Generally choose in the selection, from the form, usually choose rivet with better riveting performance and beautiful appearance.

Choose a relatively large surface, usually can withstand relatively large pressure, but also pay attention to its recognition degree.

When selecting, attention should also be paid to whether it has good fastening performance during use, especially when using plastic or metal plates.

Rivets are widely used in doors and Windows, automotive industry, transportation and other industries. When choosing, in order to ensure quality, a regular manufacturer should be selected.

Fasteners are the most common parts of mechanical equipment, and their functions are also very important, but corrosion is the most common type of damage during the use of fasteners to prevent corrosion during the use of fasteners

Many manufacturers will perform surface treatment after fastener production, which surface treatment can improve the corrosion resistance of fasteners? There are four surface treatment methods to prevent corrosion of fasteners, and we can choose the most appropriate method according to specific needs:

Electroplating

A standard part is plated by placing it in a metal solution and then applying an electric current to the surface of the standard part through a layer of metal. There are many effects on this layer of metal. For example, we can use some different functions. Choose a few different plating metals, if you want to prevent the standard parts from rusting, you can electroplate Dacromet on the surface of the standard parts.

Mechanical plating

Machining standard parts is to cold weld metal particles to standard parts to ensure certain functions of the surface of standard parts. Mechanical plating and electroplating are basically similar, except that the methods we use are different, and the results can be said to be the same.

Heat treatment

In order to heat treat the surface of a standard part, there are some standard parts. For example, a drill screw requires a relatively hard surface layer, so the drill screw can be heat treated to ensure that the drill screw has sufficient hardness. This is the reason for the heat treatment.

Surface passivation

For standard surface passivation, passivation has two main functions, one is to enhance the hardness of standard parts, and the other is to greatly reduce the oxidation of standard parts. When performing the fastener surface treatment process, we can choose the most appropriate method according to the specific needs. In this way, the fasteners will play a better role in the use process.
