Louver and Bead Making



The Vibro-Sheer is an electric power hammer tool. It hammers desired shapes into sheet metal by using a set of dies. The bottom die is firmly mounted to the lower half of the machine while the top die travels up and down in a hammer like action at high speed. The Vibro-Sheer also has an adjustable guide that allows the metal to be accurately passed through the dies at right angles. The ability to quickly change the dies and the distance between the hammered shapes makes the Vibro-sheer extremely useful in the panel making process. We have used the Vibro-Sheer to hammer beads into floor pans, beads into the edges of guards, louvers in bonnet sides & tops and domed sections in spare wheel wells.

Once the correct size die is selected the machine is setup. The beads are marked out on the metal and the guide is set to allow the panel to pass through the dies. The machine is then started and the hammer action starts. We then lower the top die onto the sheet metal and the beading process begins.

For edges around guards the process is the same however instead of the adjustable guide allowing the metal pass through at right angles to the dies. The guard panel is setup on a bed with a rolling clamp system. The outer edge of the guard is clamped and this allows the edge to pass next to the dies. So the bead follows the outer edge of the panel. This gives the raised appearance on the guard edges. Usually the underside is then turned over to form the wire edge.  

Louvers can be made any length due to the way the Vibro-Sheer dies cut and hammer the shape into the panel at the same time. The minimum spacing between the louvers is about 20mm. By spacing the louvers further apart we can create different looks and styles to suit your needs. By lengthening and shortening the louvers they can follow the contour of a guard, avoid important items in the engine bay or give your custom job an art deco look. There are two types of louvers French and English. French louvers are punched down into the bonnet side. This makes the bonnet side appear to be flat on the outside with the opening facing forward to allow the engine heat escape. English louvers are punched upwards on the bonnet sides. This gives the louver a raised appears on the outside. The opening faces towards the rear to allow the engine heat to escape. Louvers are also used in inner guard panels, air-condition outlets, de-mister outlets units, and under trays.

We have a standard sized louver die that we use for most louver jobs. We can modify the louver size however this is very expensive in comparison to using the standard sized louver die. This is usually reserved for accurate reproductions of original panels.
