Formed aluminium covers
Curved forms can be achieved in sheet metal by rolling, forming with the correct sized curved form tool in a press or using a multi bend technique to simulate the curve circumference with straight sections at a tangent to the curve. These small aluminium covers were formed up by rolling as they were only a small batch. We have the ability to move from one type of forming to another depending on the volumes involved in each project and even over time if volumes improve often adapting tools we have to suit with custom made sleeves.
Folded aluminium brackets
Here are some small aluminium support brackets for tiny LED light fittings made in a batch of approximately 100 off. The parts were 3D modelled in Radan sheet metal CAD/CAM software, CNC programmed for one of our Trumpf CNC punch presses, punched out, de-burred and bent up in 3 working days. They still have on the protective white plastic film at this stage to keep the outer faces free from being scratched as they will eventually be silver anodised for a decorative finish.
Punched brass washers
We don’t manufacture that much in brass so these small brass washers immediately caught my eye on our goods out inspection bench. They have simply been CNC punched out and then barrel de-burred to remove any sharp edges. We make a range of these washers in several gauges and diameters. If we don’t have the exact tooling as standard on our CNC punch presses and there are only small batch sizes we can always laser cut them with our Trumpf 3030 fibre laser which can happily cut brass and copper sheet up to 6mm thick.
