Abstract:
1. A production method for incorporating an object into a multi-part casing that is at least in part transparent, comprising: providing a first plastic casing part with a first joint surface and positioning form; providing a second plastic casing part with a second joint surface; diamond polishing at least one of the first and second joint surfaces to form a planar, transparent, and mirror-finish surface; inserting the first casing part, the second casing part, and the object into a hot vacuum press so that the first and second joint surfaces face one another and so that the object is aligned within the positioning form; bringing the first and second joint surfaces together within the press while the object remains aligned within the positioning form and between the first and second joint surfaces; fusing the first and second joint surfaces within the press by subjecting the joint surfaces to a pressure force and to an elevated temperature so that the first casing part on the first joint surface makes a transition to the second casing part on the second joint surface devoid of a visible seam; and providing a vacuum before or during fusing to prevent air inclusions from arising between the first and second casing parts, wherein one of the first and second casing parts comprises a rim that is circumferential at least in some sections, wherein the other of the first and second casing parts comprises an elevation, and wherein the first and second casing parts are brought together so that the rim engages the elevation with a positive fit.
