What is The Process of Making A Rivet?
The manufacturing process of blind rivets is generally divided into 7 steps. From the manufacture of the rivet body to the manufacture of the rivet head and finally the assembly together. Below I will describe in detail the manufacturing steps of this Blind Rivet.
1.Raw Material Selection
In the production process of blind rivets, the choice of raw materials is very important. This is because different materials have an impact on the performance, durability and range of use of the product.
Before all the business begins, the first thing you need to confirm is the right material for your project. This is because chemical reactions may occur between different materials, leading to unnecessary damage.
Some of the commonly used raw metal materials are steel, stainless steel, aluminium, monel alloy and copper. If your project requires high strength, then you should choose blind rivets made of steel. If your business requires corrosion resistance, prefer rivets made of stainless steel.
2.Cold Forming
Once you have determined what materials you need for your blind rivets and presented them to your rivet manufacturer, the blind rivet manufacturer will begin making the blind rivets.
Cold heading is an important step in the production of blind rivets, as it processes the raw material into the initial shape of the blind rivet. It is done by cold extruding the raw material into the shape of a rivet with a hollow core.
As the raw material is subjected to greater pressure and deformation during the cold heading process, this deformation can increase the strength and density of the material through plastic deformation, so that the blind rivets have sufficient strength and stiffness.
There are many benefits of using cold heading in the manufacture of blind rivets, including:
- Increase the strength and density of the material
- Elimination of surface defects and irregularities in raw materials
- The ability to mass produce blind rivets in a shorter period of time saves time and costs and improves production efficiency.
3.Thread Rolling
Once your blind rivets have been cold headed, you move on to the next step: thread rolling.
Thread rolling is also an important process step in the production of blind rivets. It plays a role in the production of blind rivets by increasing the connecting force, improving resistance to loosening, facilitating installation and disassembly, and improving adaptability and application range. These properties enable blind rivets to provide more reliable, stable connections and solutions.
The following are common benefits of thread rolling in the production of blind rivets:
- Increase the connection force: thread rolling can form a threaded structure on the external surface of the blind rivet, thereby increasing the friction between the material to be connected.
- Improved resistance to loosening: As a result of the threaded structure formed by the thread rolling, the blind rivet can better resist loosening during the joining process. The threaded structure increases the close contact with the connected material, improving the stability and reliability of the connection.
- Improved adaptability and range of applications: Thread rolling allows the blind rivet to be adapted to different materials and connection requirements. By choosing the appropriate thread size and type, it can be matched with a variety of connected materials and connectors, expanding the scope of application of blind rivets.
4.Head Treatment
Once your blind rivets have completed the cold heading and thread rolling process, the next step is to produce the rivet heads. As you know, a blind rivet is made up of a rivet nail and a rivet head.
The rivet head treatment can be modified and reinforced by pressurisation, stamping or other processes. A high-quality rivet head can bring good benefits, including increasing the strength of the connection and ensuring the reliability of the connection. After all, the connection of a blind rivet depends on the deformation and expansion of the rivet head.
5.Laser Selecting
Rivmate, as one of the top Blind Rivet manufacturers and suppliers in China, chooses to use laser picking to screen the rivets produced.
We use laser picking for quality control of blind rivets.Rivamte’s laser equipment can detect cosmetic defects, surface imperfections and other undesirable characteristics of rivets. By detecting and screening for these problems, we can ensure that the rivets meet international standards and reduce the number of defective products.
Laser picking is highly accurate and consistent. The ability to detect and sort at very high resolution ensures that each rivet is selected correctly. This ensures that the quality of your rivets is consistent and reliable.
6.Assembly
Assembly is the final step in completing the production of blind rivets. After the production of the head and body of the blind rivet, they are assembled together to form a complete blind rivet product.
The steps of assembly are as follows:
1. Insert the rivet head into the rivet body, making sure that the head is tightly connected to the body.
2. Make sure the connection is solid. Rivets are designed with raised or grooved structures, which can increase the tightness and stability of the connection.
3. After the installation is completed, the assembled blind rivets need to be checked and adjusted.
7.Packaging
When the step of packaging is carried out, it means that your blind rivets have been manufactured and only need to be completed and packaged before they are ready to be shipped to you!
Packaging is also an important part of the process, in the process of sea and air transport, the product will be subjected to pressure of the pressure of the squeeze, drop and so on. Packaging can provide a good protection against damage or deformation of the Blind Rivet during transport, storage and handling.
And the packaging can be attached with product identification and information, such as product model, specifications, quantity. Production date and so on. It can reduce the occurrence of confusion and error.
How Are Rivets Assembled?
Blind Rivets are made up of two parts – the rivet head and the rivet body. To get a reliable blind rivet, these two parts need to be produced separately and then assembled together. So how is a blind rivet assembled and How Are Rivets Manufactured?

Why Are Rivets Heated?
Heat treatment is a special treatment for blind rivets. Please note that not all blind rivets require heat treatment. You will need to judge the need for heat treatment based on your actual application.
There are many benefits to heat treating blind rivets:
- Improve the wear resistance and deformation resistance of blind rivets.
- Improved strength and tensile strength of blind rivets
- Improving the toughness of blind rivets
- Adjustment of material properties
Whether or not you want to heat treat your blind rivets, you can make a judgement in several ways.
If the application scenario of your business requires high strength of the Blind Rivet, which needs to withstand large tensile or shear loads. Then heat treatment is recommended.
In some application environments, the blind rivets will be subject to high friction or abrasion, at this time you need to heat treat them to improve their abrasion resistance and deformation resistance, so as to extend their service life.
If the blind rivets need to work in high temperature environments or extreme temperature conditions, heat treatment can make them have better heat resistance and high temperature resistance.
Of course, heat treatment can reduce the stress and improve the resistance to stress corrosion cracking of the blind rivets.
Why Import Blind Rivets from China?
Global customers choose to import blind rivets from China, usually for the following reasons.
