Part bent sections – first stage of bending
Brass is such a nice sheet metal material to work with in a modern sheet metal working factory. We can CNC punch it in just the same way as we would punch out mild steel, aluminium or stainless steel. No special tooling or processing is needed to produce the flat blanks straight from standard sheets of metal. We are also really lucky in having a Trumpf 3030 fibre laser which enables us to laser cut both copper and brass sheet up to 6mm thick where CO2 lasers would not be able to process these materials we can laser cut them in just the same way that we would cut stainless steel, mild steel or aluminium. It’s just the same with bending brass sheet metal components. The same tooling that is used on all our CNC press brakes can be used with brass. These surround parts for a box housing have had the first 2 bends already folded up on the Safan e-Brake at this stage with basic V bend tooling.
Sheet metal bending in progress
In this photo you can clearly see the back stops on the Safan e-Brake CNC press brake setting the depth of the bend to be formed. You can also see the top and bottom V tooling and a gap set between them so the final bend of the box surround can form between the tooling. There is also some thin plastic V block protection material clamped to the tooling to help prevent the outer surface of the brass being marked when the bend is being formed. The brass sheet also have a thin protective peelable film of plastic on it which helps to keep it scratch free and the customer can peel this off when they are ready without any residue being left on the component.
Finished sheet metal work housings
The final box surround components have been folded up and just need to have a couple of tack welds to hold them together into a rectangular shape. An engraved face plate completes the assembly and creates a housing for door entry equipment for flats. Although brass is not a common sheet metal to work with today it still has a part to play and we make a series of components from items like these boxes to brass menu display boards, decorative light fittings, decorative strip shopping fittings and electrical contact clips. Perhaps you have a brass sheet metal component? We would happy to take a look and produce some prices for you.
