Sheet Metal Joining Without Fasteners

The clinching process is a method of joining sheet metal or extrusions by localized cold forming the materials.

Sheet metal joining without fasteners.

Screws on the other hand hold a joint together by griping a thread cut into the metal. A simple symmetrical clinchrivet is used as the joining element to produce a clinch connection without cutting the material. Nuts can be welded to the sheet metal which eliminates the need to reach both sides and self tapping screws cut their own thread. It is possible to join metal pieces by methods like riveting soldering bolting or brazing.

Self tapping is the use of self tapping screws to directly tap the thread on a piece of sheet metal so the fit is very good and can be disassembled. Applications in the crash zone of passenger cars are best examples for the capabilities of this versatile joining method. It creates an interlocking of two or more metal layers. 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. 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. The result is an interlocking friction joint between two or more layers of material formed by a punch into a special die.

Other than this nano metals and adhesives can also be used to join metal pieces together without welding. Painted or coated metal sheets can also be joined by this method without damaging the surface. Sheet metal clinching joint creates a button type positive connection between two or three layers of sheet metal. Advantages of clinching joints additional fasteners are not required.

The clinching process is a method of assembling sheet metal without welding or fasteners. Join metal parts in a cost effective and sustainable way with rivclinch. Both need holes through the sheet metal but bolts use a nut on the backside to tighten the joint.
