Example

Elson Designs were selected to improve the design and productivity for an existing product with annual sales in excess of 2000 units.
The company had previously been advised to use the Investment Casting process for design criteria.
When considering their requirements Elson Designs suggested an Extrusion was the most cost effective solution.
As costing example below shows, extrusion alone produced an Annual Saving of
? £486,000

Investment CastingExtrusion
  • Tooling - £5,000
  • Batch Size - 200
  • Cast price including machining - £265 each
  • Annual cost for 2000 = £530,000

Access to secure backplane was very difficult. PCB’s assy were guided onto backplane. PCB’s assy were screwed to casting. RH side connector alignment was very difficult. LH side connector build-up was very difficult. Interconnecting cables were prone to damage. Cover secured.

  • Tooling - £7,000
  • Minimum Batch Size - 450
  • Extruded price including machining - £22 each
  • Annual cost for 2000 = £44,000
  • Annual Saving = £486,000

Assembly was aided by sub-assemblies Backplane assy was secured to extrusion. PCB’s assy were guided onto backplane. Connector plate assembly was secured to extrusion which also secured PCB’s.

Assembly time was reduced by over an hour Product reliability improved.
