Abstract [en]

This degree project, conducted at Prevas AB, investigates if there is potential reduced production costs due to a change of material of the casing of a Digital Breathalyzer, with retained product characteristics. Considering the using of the product, 5 materials are presented and compared with respect to mechanical and thermal properties. A material analysis containing a merit value table is made and a new casing made of ABS/PC biocompatible plastic is chosen and redesigned with lowered production costs as a result. Return on Investment (ROI) in years and number of produced pieces is calculated with respect to necessary investments and potential reduced costs. With a production rate of 1000 and 4000 pieces per year the ROI is 11,2 and 2,76 years respectively, and ROI regarding production volume is 11 204 and 11 049 pieces respectively. 

Abstract [sv]

Detta examensarbete, utfört på Prevas AB, undersöker om det går att minska produktionskostnaden genom att byta material av höljet på en digital alkoholmätare, med bibehållna produktegenskaper. Med produktens användande i åtanke presenteras och jämförs 5 alternativa material med avseende på mekaniska och termiska egenskaper. En materialanalys innehållande en meritvärdesanalys genomförs och ett nytt hölje av materialet ABS/PC biokompatibel väljs och designas om med en lägre produktionskostnad som resultat. Avkastningen mätt i år och antal producerade produkter kalkyleras med avseende på nödvändiga investeringar för projektet och potentiella minskade kostnader. Med en produktionsvolym på 1000 och 4000 per år blir avkastningen 11,2 och 2,76 år.Avkastningen i antal producerade produkter är 11 204 och 11 049.
