Die heads - Import export

Self-clinch studs are fasteners that have a serration under the head. At inserting into the metal sheet it presses the displaced material into the rivet ring to secure the fastener. Sheet metal fasteners with internal and external threads are especially suitable for working with thin metal sheets starting with 0.5 mm thickness. This reduces the thickness of the elements in general in favour of lower weight and less material. Aft er processing they are permanently connected to the base material. The screwed connecti ons can be removed aft erwards without risking displacement of the fastener. Through this the production processes are rationalized and secured.

During the setting process, edges on the mandrel head cut the rivet shaft into four segments. These four segments then unfold on the component surface thus forming the large locking head. Once the mandrel reaches its predetermined breakload, the mandrel head falls out of the rivet body. The large locking head allows connecting soft or britt le components and helps transfer high tensile forces.ARCO body-bound blind rivets are preferably used for plastic or wood element assembly, caravan manufacturing and fastening of cladings.

According to the ARCO body-bound rivet the folding rivet forms a large upset head too. Thisguarantees an equal distribution of forces, so that especially plastics and other soft or vulnerable materials resist against cracking or pullthrough. Typically this rivet is used in all areas of industrial light weight constructions. As a result of the locked mandrel in the connection, the spread rivet is splash water resistant. VVG offers two different types – the standard split rivet and a high strength version with neoprene washer.

SFM-PL folding blind rivet nuts are constructed for those applications where a high pull-out strength is requested. The slottedshaft makes the rivet nut split into four straps with a wide contact surface that guarantee an equal distribution of forces especially on plastics and other vulnerable materials. Furthermore this type offers a very big grip range! SFM-PL folding blind rivet nuts are for example used in all fields of vehicle manufacturing.
