About the assignment
Westal needed a seamless cover to reduce rust attacks since the lamp cover was intended for outdoor use and needed to withstand rain and moisture. A simplified manufacturing process, with fewer steps for a cheaper product was also on the wish list.
The execution
With the help of deep drawing, we at Ingelsten were able to manufacture a cover completely without seams and in fewer production steps as we only use a sheet metal that is bent to the right shape. By using treated sheet metal, no extra surface treatment was required.
The result was a more efficient and cheaper production and a final product with fewer seams, better quality, and a higher surface finish.
About Westal
The lighting company Westal had a recessed ceiling light for outdoor use made from three plates that needed to be cut and then bent. After that, the plates were welded together, resulting in many seams. Finally, the entire cover was treated to prevent rusting.
