Wire Erosion – Heat Sink Prototype

Project Name: Wire Erosion – Heat Sink Prototype

Industry Sector: Electronics

Type of Work: Wire Erosion

Client Requirements:
Cheshire Wire Erosion are renowned for precision engineering and it is because of this that we are constantly acquiring new clients. We often find that a company approaches us as a result of a referral from an existing client, for example we were recently approached by a subcontractor who had been told about us.

As a matter of urgency, the subcontractor required an aluminium 6082 Heat Sink prototype. They needed it to be engineered within 2-3 days. The client was also working within a tight budget, so the job had to be completed at the right price. As with both our new and established clients we always endeavour to produce pieces that are cost effective and delivered on a short lead time when needed. Whatever the client requires we will try to accommodate them.

In this instance the subcontractor had approached several other companies before they heard about Cheshire Wire Erosion, and was having difficulty identifying anyone who could supply the heat sink prototype within such a tight deadline. They were running out of options. With our in-house skills, expertise and experience as well as the technology we have invested in, setting us a tight deadline is very rarely a problem that we can’t overcome. We thrive on being set a challenge! However, we can create precision pieces in a short space of time.

Work Carried Out:
Aluminium is lightweight and is a brilliant conductor of heat, making it the most preferred material used in the production of heat sinks. When a heat sink is made of Aluminium it provides good thermal and electrical conductivity combined with low weight and high strength. It is also resistant to corrosion.

The electronic prototype that was required by the subcontractor had dimensions that were 300 x50 x 200mm. To complete this task, we used our Sodick AQ900L to wire erode the aluminium heat sink prototype. This is the perfect piece of equipment to use because it is highly rigid making it ideal for machining large sized dies.

When we use this type of machinery, we can precision machine, delivering greater accuracy and a fine surface finish.

You can see the finished product from the photographs included.

Outcome:
Custom designed heatsinks are an indispensable component in the production needs of numerous industrial electronics manufacturers today. With many pressures on this industry most companies require the work that we do to be done to a tight deadline. They don’t have the time and resources to wait weeks for a customized heat sink. We understand this and we know how essential it is for heat sinks to be produced quickly and effectively, that’s where we can help at Cheshire Wire Erosion.

At Cheshire Wire Erosion we have also machined precision parts for companies in a wide range of industries not just the electronics industry. We recognise how important it is to work closely with our clients to ensure that every heat sink is created to their specifications. We understand that being thermally efficient and cost effective are equally important, so we always aim to provide a superior service and a fast turnaround time.
