Sheet Metal Joining Without Fasteners

Other than this nano metals and adhesives can also be used to join metal pieces together without welding.

Sheet metal joining without fasteners.

The result is an interlocking friction joint between two or more layers of material formed by a punch into a special die. By means of clinching joining technology steel and stainless steel materials as well as aluminium and other non ferrous materials are joined together without welding or fasteners. Painted or coated metal sheets can also be joined by this method without damaging the surface. It is possible to join metal pieces by methods like riveting soldering bolting or brazing.

Welding is not an easy process and not everyone knows the proper way to do it. A simple symmetrical clinchrivet is used as the joining element to produce a clinch connection without cutting the material. Advantages of clinching joints additional fasteners are not required. Both need holes through the sheet metal but bolts use a nut on the backside to tighten the joint.

The clinching process is a method of assembling sheet metal without welding or fasteners. It creates an interlocking of two or more metal layers. Screws on the other hand hold a joint together by griping a thread cut into the metal. Sheet metal clinching joint creates a button type positive connection between two or three layers of sheet metal.

Clinching uses cold forming to assemble two or more layers of metal sheets. Nuts can be welded to the sheet metal which eliminates the need to reach both sides and self tapping screws cut their own thread. The clinching process is a method of joining sheet metal or extrusions by localized cold forming the materials. Installation procedures devices and systems for joining sheets and profiles without fasteners.

With this joining technique metal parts are deformed locally without the use of any consumables. Folding and adding bending tabs is one of the easiest and most economical way of making moderately strong joints in sheet metal parts that will permanently or semi permanently attach to one. Pressing rivet the pressing rivet process presses the crimp nut or screw against the sheet metal and can be mated with the corresponding outer nut or screw.
