Abstract [sv]

I det här arbetet har tätningsmetoder för aluminiumhus undersökts. Arbetet avgränsades mot fordonsindustrin och statiska packningar. Examensarbetet tar upp flänskonstruktionens inver-kan på tätheten och packningen, packningstyper, ytjämnhetens inverkan på packningsmateri-al, porositet, relativ materialkostnad och fästelement.Arbetet grundar sig på en litteraturstudie och intervjuer med berörda personer på företaget. Även praktiska prover genomfördes på ett urval av material från leverantörer där material exponerades för olika kemikalier och därefter dragprovades.Materialet som insamlats genom intervjuer och litteraturstudien vittnar om att många paramet-rar påverkar vilka tätningsmetoder som är möjliga att använda. Det är inte bara materialval som det behövs tas hänsyn till. Faktorer som flänskonstruktioner, materialkostnader, ytdefek-ter, fästelement samt porositet har en stor påverkan. De praktiska proverna vittnar om att olika kemikalier har olika stor inverkan på materialens mekaniska egenskaper och svullnad.Slutligen föreslås ett par packningsmaterial som är lämpliga för företaget att använda i deras produkter.

Abstract [en]

In this work sealing methods for aluminum housing have been investigated. The work was delimited to the automotive industry and static gaskets. The thesis brings up how the flange impacts on the sealing capability and the gasket, sealing types, the surface impact on gasket materials, porosity, relative material cost and fasteners.The work is based on a literature study and interviews with concerned people at the company. Practical samples were carried out on a number of materials from suppliers and the materials where exposed to different chemicals and then tensile tested.The materials that were collected through interviews and the literature study testify that many parameters influence the possible sealing methods. It’s not just the material itself that needs to be taken into account. Factors like flange design, material cost, surface defects, fasteners and porosity have a great impact. The practical sample testifies that different chemicals have dif-ferent impact on the mechanical properties and swelling of the material.Finally, a couple of sealing materials are suggested that are suitable for the company to use in their products.
