Abstract: The present invention relates to the technical field of forming, and discloses a forming system and a forming method using the same, to solve a problem that a forming process in the prior art is intermittent and therefore has relatively low production efficiency. The forming system of the present invention includes: a main machine and a forming machine that are located at a same production line and are sequentially connected. The main machine includes an extrusion mechanism, and the forming machine includes a forming mechanism. The main machine can heat and stir a solid raw material into a liquid material by using the extrusion mechanism. The forming machine can directly process the viscous material into a formed product by the forming mechanism. The present invention is mainly applied to production and manufacturing of plastic products.
