<p>The invention relates to a frame production method that can be used to produce frames having a reduced number of pieces which are moulded entirely from plastic. Each of said pieces can have variable configurations and dimensions since each piece is obtained from a single mould. Said mould consists of one fixed part, which is used to produce the largest part of the piece, and a second interchangeable part having a variable configuration. In this way, the different pieces of the frame are removed from the mould with the dimensions and appearance required for each type of frame.</p> |
