There are many types of rivets, depending on the application: hollow, solid, semi-hollow, core, core, etc., etc., geographical restrictions also produce names in many places, but in terms of specifications It should be specified in detail: head shape diameter * head thickness * diameter * length (excluding head thickness) * aperture * hole depth, usually, the aperture and depth have been stipulated, if you do not Drawings or pictures should include these elements, and then inform the materials, they can basically be directly produced. Hollow rivets are usually used in apparel, footwear and other industries. They need to be riveted again. They are used for heavy workpiece joints. They are often non-removable structures. Semi-tubular rivets are the most widely used. The bundles (small diameter tails) are hard wire. It can be manufactured without the need for pre-holes to penetrate the steel plate with a thickness of 0.5mm. The rivet can not be bent and deformed. It is widely used in password boxes, suitcases and military bags. The hollow nails (semi-tubular rivets) are made of soft wire, which is generally required to be riveted. After cracking, there are many types. At present, the shafts on some toys have begun to be replaced by semi-hollow nails or sub-nails in a large area, which can greatly reduce the production cost. The core pulling and core rivets are mostly used for riveting of relatively thin soft materials. Generally, the requirements are not strict, and the manufacturing materials are usually produced by using a plastic material.
