Application
Tri-Fold type blind rivet also known as Lantern rivet. After the rivets are riveted, the nail hat will become like a lantern, so it is called lantern rivets. Tri-fold tite rivets have a wide range of riveting range. The same specifications of rivets can riven various thickness materials to reduce the sizes and types of rivets, and are convenient to use. Lantern blind rivets or Tri fold blind rivets are generally made of aluminum alloy (such as 5050, 5052, 5154, 5056).Lantern rivets or Tri fold rivets also have a variety of head types to choose from. Including dome head, flat head, large flange head and countersunk head.
The surface of the Tri fold rivets is large and has the following characteristics:
1. Large limit support
Tri fold blind rivets can form three large angles, distributed in a large area, and the load of dispersing riveting surfaces. This feature allows the trifold blind rivets to be applied to fragile or soft materials, or rivet holes and irregular shapes.
2. The characteristics of replacing the bottom pads of the rivet, the characteristics of the large hat rivet can replace the front and rear pads. Increase the riveting area and disperse the riveting load.
3. Multi -riveting range
The multi -riveting performance of the lantern pop rivet enables a specified rivet to riven various thickness materials and reduce the type of rivet specifications.
4. corrosion resistance
The whole aluminum structure determines the corrosion resistance of the tri-fold blind rivets
5. The nail core is firm
The tri-fold rivet core is locked, and it is not easy to fall off when used.
Application of tri fold rivets: It is mainly used for cars, such as plastic instrument panels, interiors, accessories, etc.
