Application
Structural Bulb Tite Rivet is a special rivet, also known as Tri Fold Rivet and Lantern rivet.
1. Bulb Rivet Working Principle:
During the installation process, rivet deformation is lanterns, forming three large folding feet, increasing the riveting area, and dispersing the load of the riveting surface. This makes the Bulb Rivet suitable for irregular holes or crispy or soft materials.
2. Structural Bulb Blind Rivet Can waterproof and anticorrosive:
The structural bulb rivet increases the waterproof design, and the rubber cushion ring is added during use to prevent water from invading from the rivet hat, which has played a good waterproof effect. The whole aluminum material structure determines the corrosion resistance of the Bulb pop rivets.
3. High intensity:
Another advantage of the structural Bulb rivet is that the mandrel is locked. The residual mandrel increases the intensity of the rivet. The bulb type rivets are not easy to break under shear.
4. Riveting materials:
In some materials, other fasteners can’t riveting, but bulb type rivets can play a role and are widely used. During the use, the Bulbex rivet forms three folding feet, and the clamping force of decentralized rivets on the rivet surface. This feature makes buly type blind rivets widely used in wood products, glass, plastic products, rubber, automobile dashboards, automobile exhaust systems, light boxes and other fragile and soft materials without damaging riveting materials.
5. Riveting range:
Bulb 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.
6. Appearance selection:
Bulb rivets, 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.
7. Material selection:
