They said it was impossible. AXIAM did it.
400mm by 400mm by 90mm cast aluminium heatsink
LED’s are the way of the future for lighting, and when LED experts FLC Microdesign/Coolon were looking for manufacturers to make a housing unit which acted as a cooling heatsink for their innovative high powered LED waterproof flood light system they struck a number of fundamental stumbling blocks.
The first and biggest stumbling block faced was the sheer size of the unit. Heatsinks are notorious to cast due to their extensive surface area and the resulting fluctuations in temperature. At 400mm high by 400mm wide by 90mm deep most die-casters which were approached took one look at the 532 protruding heat-sink pins on the back of the product and said ‘it can’t be done’. Not AXIAM diecasting however.
What followed next was a redesign of the entire casting process to make what would otherwise be impossible possible. Within a few days of receiving the inquiry, AXIAM diecasting were able to show FLC Microdesign/Coolon a workable solution where no one else could.
In addition to the casting challenges, this product and the environment in which it must operate also threw in some added curve balls. AXIAM have been able to grasp hold of these and run with them through innovative post processing solutions, from high tolerance CNC machining through to the customer specific coating process and product specific, grouped packaging.
No higher praise can be received than the look on the faces of those diecasters who said it couldn’t be done when they see that it in fact it can – With the right attitude!
