ABSTRACT OF THE DISCLOSURE A process for the manufacture of articles from a thermo- plastic of polyester or polyamide type, preferably of polyethyl- ene terephthalate, the articles being manufactured from elements which consist of an edge part which surrounds a body in an arrangement in which the latter is sunk relative to the edge part. The element is formed from a blank of mainly amorphous material or from a material having a crystallinity of less than 10%. The blank consists, for example, of a flat plate, a blank shell or the like. The body or parts thereof are shaped by stretching the blank until that material flows which is located within the material sections of the blank, which form the edge part in the element, the material stretched up to flowing in the body assuming a crystallinity of between 10 and 25%, whilst the crystallinity in the material in the edge part and in the unstretched parts retains its original value of less than 10%. The edge part is severed from the body which is elongated in the axial direction by a number of stretching steps, whilst the stretching at right angles to the direction of drawing is re- duced at the same time.
