A closed end rivet, also known as a sealed end rivet or sealed blind rivet, is a type of fastener used to join two or more materials together. It is called a "closed-end" rivet because has a mandrelthe central rod inside the rivet) that does not protrude from the rivet body when the rivet is set. Closed end rivets are commonly used when it is difficult or impossible to access the joint from both sides. They are particularly useful for applications where one side of the joint is not accessible or where a watertight seal is required. The closed end of the rivet prevents the passage of liquids, gases, or contaminants through the rivet hole.

What Is Advantage Of Closed End Rivet? 

1. Increased structural integrity.

2. Enhanced corrosion resistance.

3. Improved aesthetics.

4. Enhanced vibration resistance.

5. Increased load-bearing capacity.

6. Greater sealing capabilities.

7. Reduced assembly time and cost.

How Does Sealed Blind Rivet Work? 

1. Align the materials to be joined.

2. Insert the rivet into the pre-drilled hole.

3. Place the rivet gun on the mandrel.

4. Squeeze the rivet gun trigger to set the rivet.

5. Apply pressure until the rivet breaks off.

6. Repeat the process for the remaining rivets.

7. Inspect the rivet installation for proper flushness and tightness.

Production Process

Step 1

Blind rivet machine---making the rivet body

Step 2

Nail making machine---making the mandrel

Step 3

Assembly machine--finish the assembly of rivet body and the mandrel
