Vapouriser A multi hollow extrusion developed by Penlon Limited.
Background
One of the UK's leading manufacturers of medical equipment has used aluminium extrusions for their new Sigma Delta Vaporiser, the latest addition to their product range.
Developed by Penlon Ltd, the vaporiser has been designed for use with continuous flow anaesthesia machines and delivers accurate concentrations under varying conditions of flow rate and temperature.
Using the inherent flexibility of the extrusion process a multi-hollow section was designed which replaced a stainless steel blank, a cover and piping. This also negated the problem of porosity which is inherent in castings. As a result the vaporiser now exhibits a weight saving in excess of 60% when compared to the original stainless steel product.
Benefits
Despite a significant amount of complex machining, the use of an extruded aluminium section has provided significant savings to Penlon. As well as the overall reduction in the number of parts used, extrusion tooling cost savings of approximately £7000 and ongoing reductions of £20 per item have been achieved. Reduced tooling times for the aluminium compared to the original steel supply were achieved - when combined with the very quick turnaround from initial design to the supply of samples and finished product, Penlon have benefited from bringing this product to the market very quickly.
The vaporiser has an attractive silver anodised finish which is suitable for the anaesthetic gasses used and also provides a distinctive contemporary look ideal for the medical environment in which it is used.
