Method for producing a transparent body that incorporates an object

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.
