Bonding sheet metal

Bonding sheet metal to sheet metal

Bonding involves joining individual layers of sheet metal together. Bonded parts can be used very flexibly, as the individual layers can be removed gradually until the necessary thickness for tolerance adjustment is achieved. Bonding is used especially for the production of peelable shim washers. We distinguish between two types of bonding: flat bonding and edge bonding.

Flat bonding

For the production of laminate or laminated sheet, metal sheets or plastic films are bonded together over the entire surface. The result is foil packages made of extremely thin individual layers with a foil thickness starting at 0.01 mm.


Advantages of bonded laminated sheet:

  • Extremely thin individual foils
  • Compact nature of the foil packages

Dexterity and accuracy

One disadvantage of flat bonding is the difficulty in removing the individual sheets. Peeling requires a great deal of dexterity and accuracy. In addition, when peeling laminated sheet, there is a high level of material scrap. The removed films cannot be reused. In addition, the use of flat-bonded laminated sheet involves a high risk of injury, as the sharp-edged individual sheets have to be detached with the aid of a knife.

The disadvantages can be minimized by using machining production methods when processing laminated sheet parts. In contrast to the punching process, in which the individual sheets are pressed together and are therefore more difficult to remove, the parts are formed by means of drilling, milling, or turning without pressing. This results in better removability.

Edge bonding

In edge bonding or edge binding, individual foils are bonded together only at the edges, as in the case of a paper pad. The minimum thickness of the individual layers for edge-bonded shims is 0.05 mm for edge-bonded parts.


Advantages of edge-bonded sheets:

  • Very easy to remove
  • Minimized material scrap and reduced risk of injury
  • Reusability of removed parts

Edge bonding vs. flat bonding

The disadvantage of edge bonding compared to flat bonding is on the one hand the thicker minimum thickness of the individual films, and on the other hand the less strong bond between the layers, which can be a hindrance in some applications.

While laminated sheet parts are manufactured from already bonded laminated sheets, edge bonding takes place only after the individual sheet parts have already been formed. Punching therefore does not have a negative effect on removability here.
