Lighting reflector made from anodised aluminium – held together by ‘toy tags’

Monday, February 7th, 2011

toy tag assembly

Sometimes sheet metal parts can be tricky little things to join together if they cannot be made from one piece of metal.  This reflector assembly has a group of sheet metal fins that need to be held in place inside an outer frame.  Being pre-anodised aluminium with a highly polished surface they cannot be spot welded or TiG welded and anyway they are far too thin for that being made from 0.4mm thick material.  The design needed to be clean too, so no nut and screws were allowed as they would have blocked the light output through the reflector.  Where no great strength is needed in the finished part and the parent sheet metal can be easily bent with your fingers toy tags becomes a useful design solution.


Corner joint

Toy tag assembly can also be a useful method of assembly in production too if you want to receive your parts as a flat kit and clip all the parts together yourself.  This can also be helpful when you have several designs with common parts that can be stocked and used as each order for a variant is received.

For further advice on designing for CNC punching please see http://www.vandf.co.uk/cnc-information.html
