A method for the manufacture of a container for liquids, the container being comprised of a plurality of plastic components, and the method comprising forming a series of welded joints between adjacent components such that the components become fixedly inter-attached in a joint region, the formation of the welded joints being effected by arranging at least two plastic components in the required relative alignment adjacent each other, exposing the joint region to incident radiation having a wavelength outside the visible range so as to cause melting of the surface of one or both components at the joint region and allowing the melted material to cool, thereby welding the components together, wherein a radiation absorbing material having an absorption band matched to the wavelength of the incident radiation, so as to absorb the incident radiation and generate heat for the melting process, is provided at the joint region in one of the components or between the components. The method is particularly applicable to the manufacture of tanks for use in processors, most particularly, the manufacture of tanks for lithographic printing plate processors. |
