| 摘要 |
This invention concerns a method of making foamed plastic products, such as panels or tubes, comprising injection of a liquid thermosetting plastic under high pressure into a slightly inclined mould (4) having ventilation valves (5) or openings in its highest part for evacuating air and/or gas. The invention is characterized in that the injection is performed through at least two injectors (3) oriented in such a way that the jets (6) of thermosetting plastic or the components thereof, streaming out of the injectors (3) intersect, whereby the thermosetting plastic, when the jets (6) strike against one another, disintegrates and is evenly spread inside the mould (4). |
