A pressure tool for applying a pressure force during the welding of plastics components has at least one metallic first component contact section, wherein the pressure tool has at least one elastically deformable second component contact section and is thermally controllable. A Pressure apparatus has at least one such pressure tool for pressing together plastics components during welding. A method for welding plastics components is carried out by such a pressure apparatus and plastics module having at least two welded-together plastics components, wherein the at least two plastics components are welded using such a method.

A method of manufacturing an artificial eye for fitting as a whole or partial replacement of a patient's original eye. This is done by providing an image of an iris on a substrate (100, 300) comprising at least a frontal region of an artificial eye, providing a support (108, 308) for the substrate, positioning the substrate and support in a mould (122, 322), and encapsulating the substrate within a mould material (136, 336).

Provided is a resin molded product having excellent scratch resistance. The resin molded product of the present invention is a resin molded product including a methacrylic-based resin composition, in which the methacrylic-based resin composition contains a (meth)acrylic-based polymer (A) and a fatty acid compound (B), and an absorbance ratio P1/P2 of a peak absorbance P1 in a wave number range of 1630 to 1650 cm.sup.1 to a peak absorbance P2 in a wave number range of 1710 to 1730 cm.sup.1 on a surface of the resin molded product, measured by a single reflection ATR surface reflection method with an infrared spectrophotometer, is 0.0040 or more.
