Laser cutting sheet metal light fittings

Laser cutting sheet metal light fitting gear trays

I always like it when a laser cutting or CNC punching nest completely fills a sheet of metal. This laser cutting nest of 0.7mm zintec lighting gear trays was just such a job. Being able to get the most from a sheet of metal helps to keep the costs down for our customers and speeds up production with less handling time. The middle image above shows this really well and the other two detail some of the features that were so easily laser cut. After several small batches of samples and development work this was the first production batch of 100 parts. If the volumes increase to many hundreds per batch then I may well look to move this job to one of our Trumpf CNC punch presses to increase the speed that the holes are processed but at the moment the Trumpf fibre laser is perfect for this job. Being able to move jobs between different production methods is a useful way of saving our customers money and time when a particular machine is busy.

If you have a sheet metal project that needs to be laser cut or CNC punched please give us a call on 01489 577786 or send us an e-mail with your drawings to sales@vandf.co.uk


Welding mild steel plates and bars

Welded fabrications

Welded fabrications

Here’s an unusual project for us here at V and F Sheet Metal, a welded plate and bar fabricated assembly. The bars have been machined from mild steel and free issued to us. We laser cut the circular plates and then welded them in plate as you can see in the image here. Finally we had the welded assembly zinc plated and colour passivated. The final welded fabrication was used to support light fittings in the ground.

Although we predominately produce our work from sheet metal in ferrous and non-ferrous alloys we do also make up fabrication like this when needed for our customers. When you are a sub-contract engineering company you have to be able to turn your hand to any project that comes along from your customers.

Perhaps you are looking to have a welded fabrication project manufactured in the near future, please give us a call and we will be happy to help you.


Sheet metal components in April 2016

Sheet metal components

Sheet metal components

Here we are at the end of April and here’s another couple of sheet metal components that we have made this month. They are typical of the sheet metal components we make on a daily basis for our UK and European customers and they were each made in batches of several hundred. The components have been CNC punched and bent up from zintec coated mild steel sheet metal. If you click on the image you can see 3 holes in the middle of the component that have a plunged form and are used with self tapping screws. We have the tooling for M3, M4 and M5 as standard in our Trumpf CNC punch presses. Once we had finished them they were used to hold control gear for industrial light fittings and were just left self colour zintec as this was good enough for the warm dry environment into which they were going.

These brackets were laser cut and then CNC folded on one of our CNC press brakes. They were also made from zintec sheet metal and are used by a pump control company to hold a pumping system in place where beer is pumped from the kegs to the bar in public house cellars.

For more information on sheet metal components and how we go about making them take a look at our web page “What is sheet metal and how is it made”


Folded sheet metal work

Folded stainless steel brackets

Stainless steel folded brackets

Here are two recent folded sheet metal work projects I have chosen at random to demonstrate the versatility of sheet metal. These stainless steel brackets have been laser cut with the fibre plastic protective film in place and then folded again on our Trumpf 7036 CNC press brakes. These brackets were made in a batch of 30 parts and are made perhaps twice a year. Both CNC bend programs along with the CNC punching and laser cutting programs are stored on our company server and are available to the machine setters as all the CNC machines are on our company network. This leads to quick retrieval of past programs and storage of updates for any person who needs to access them.

Folded aluminium brackets

These 1.2mm thick aluminium brackets have been CNC punched and folded up on one of our Trumpf 7036 CNC press brakes. The batch size was 250 parts and they were a repeat order which we make several times a year. We can manufacture virtually any type of sheet metal brackets in mild steel, galvanised steel, zintec, aluminium, stainless steel, aluminium alloys, copper, brass or pre-painted materials. For more examples of sheet metal brackets please take a look at our gallery.

Please give us a try and we will be happy to quote for your folded sheet metal work needs.


Laser cutting copper sheet metal work

Laser cutting copper sheet metal

Laser cutting copper sheet metal

Having a fibre laser cutter has been a great advantage to us when it’s come to cutting out blank shapes from copper sheet. These simple triangle shapes could have been CNC punched but we would have wasted more material, we would have had to edge de-burr all the shaped to remove the CNC punch marks and the process would have been a lot slower. The Trumpf 3030 fibre laser cutter cut the parts straight out without any edge de-burring and used all the sheet here possible to get the best fit of components.

The pattern of copper triangles was arranged by using our Radan CAD/CAM software with it’s schedule module. It enabled us to mix several different shapes and sizes of copper parts together all laser cut from the same thickness sheet to save material and money across the whole project. Whenever we are working with expensive materials like copper sheet we try all possible solutions to get the best material yield when quoting for the work and then actually laser cutting it.

If you have a sheet metal project in copper or brass and you have been told it can’t be laser cut, look again, up to 6mm thick and we can laser cut it for you.
