Powder coated angle brackets
These heavy angle brackets have been laser cut from 4mm thick mild steel, bent up at 70 degrees internal angle and then powder coated bright orange and packed into individual plastic bags to protect them. These angle brackets were originally manufactured by CNC punching on our Trumpf 200 punch press with a lot of de-burring after. Now we have a laser cutting machine we have managed to reduce most of the de-burring and produce a much cleaner smooth component. We have lots of components powder coated every day using several local powder coating companies enables us to provide a flexible service.
Galvanised mild steel brackets
Walking past one of our Trumpf 7036 CNC press brakes I spotted a batch of small galvanised mild steel brackets being bent up. The brackets had been CNC punched earlier and de-burred and were being bent into an angle and stacked into a box ready for collection by the customer. Although we manufacture very complex sheet metal work we also often make simple single parts like these angle brackets.
Small aluminium plates
Large sheet metal components whether they are CNC punched or laser cut may be left with cutting burrs if these are not important for the customer. Some parts that are powder coated often don’t need any form of de-burring as the powder coat covers the edges and softens the feel of the component. There is another solution to this problem which is to barrel de-burr smaller components. The small aluminium plates shown here have been CNC punched and then rumbled in a barrel with water and ceramic stones. The action of tumbling together for 30 minutes or so removes not only the outside edge burrs but any sharp edges around the CNC punched holes. They are drying here on cardboard before being shipped out.
