Title:
EXPANSION VESSEL
Document Type and Number:
WIPO Patent Application WO/2013/151441
Kind Code:
A3
Abstract:
The present invention relates to amethod of manufacturing an expansion vessel comprising a housing and a membrane which divides the housing in two volumes, the method comprising: -providing the housing, -providing a membrane comprising a thermoplastic material, -providing a mould having a non-flat form, -providing a vacuum/blowing device which is constructed to deform the membrane according to the shape of the mould by providing an over pressure or under pressure on one side of the membrane, -providing a heating device which is configured for providing heat to the membrane during the vacuum/blow moulding process, the method comprising the further steps of: -deforming the membrane with the vacuum/blowing device according to the shape of the mould, while providing heat to the membrane with the heating device, thereby allowing the thermoplastic material to deform plastically, -cooling the deformed membrane to below the temperature wherein the thermoplastic material deforms, thereby forming the thermoplastic material in a non-flat form according to the shape of the mould, and -connecting the membrane directly or indirectly to the housing of the expansion vessel.
