| 摘要 | The invention relates to a method for working a plate-shaped material into a final product, comprising the steps of: i) feeding a rectangular baseplate to a deforming tool; ii) working the rectangular baseplate in said deforming tool; iii) removing the worked baseplate. The object of the invention is to provide a method for manufacturing a baseplate having a greater stiffness and a reduced depth or height dimension. In accordance with the method according to the invention, step ii) to that end comprises the sub-step ii-1) of upsetting the baseplate by exerting an upsetting force on at least one circumferential edge (11) of the baseplate. This makes it possible to realise a baseplate having a significantly improved stiffness and strength whilst retaining limited constructional dimensions. As a result, such a baseplate can be used as a backplate for a portable device, which backplate will be capable of accommodating a display screen with a sufficient degree of stiffness or strength, also in the case or large dimensions, whilst in addition this will not lead to unnecessarily large dimensions of the device in question. |
