In a reflector mood at V and F Sheet Metal!

V & F Sheet Metal Co. Ltd News and PR from V & F Sheet Metal Co. Ltd - Published 26 June 2018 Producing reflectors by joining individual sections using tabs and slots
Yes today I’m talking about the latest batch of reflectors we recently made in our factory! So if you’re interested in the process of reflector assembly then please read on.

3D modelling was employed to accurately calculate the reflector shapes and sizes that would fit together to produce the final reflector assembly. Each part was made using the same material, Alanod 33PG 0.4mm thick reflector aluminium. The 4 individual pieces of metal were joined together to produce a circular reflector.

The red sections have tabs on their outer edges, these fit in to corresponding slots on the sides of the green sections. This is a cheap method of assembly as the tabs and slots do away with the need for other components such as bushes and studs. This is always attractive as cost is kept to a minimum. In addition, the method of assembly is relatively easy. The reflectors could be assembled by V and F Sheet Metal or alternatively the customer may prefer to do this, again offering a potentially attractive cost saving choice for the customer. It goes without saying that this method of assembly is obviously only useful when the metal being used is thin and soft enough to be deformed by hand.

After the modelling using Radan software we needed to develop the flat blank and nest the components together to produce the best yield from the material. In this case both parts were mixed together in the same nest. Parts were punched out on our Trumpf 200 CNC punch press from sheet aluminium 2m long x 1.25m wide.

With this particular job the material chosen by the customer had a convex hammer pattern, but it is also available in a concave design. The convex arrangement produces a soft lighting effect which would be useful in certain situations where a soft/background lighting is required.

If you have a product that you think may benefit from using tabs and slots then please give us a call on 01489 577786 or email if you prefer at [email protected] Our sheet metal engineering team are always happy to help and love a challenge. With over 50 years experience between them there’s not much they haven’t come across in the world of lighting.

Please take a look at our blog for more information and images of reflector production.
