| 英文摘要: |
| Aiming at the conventional extrusion defects of low utilization rate, high energy consumption and poor uniformity, approaches such as improvement of mold structure and change of action mode were adopted to realize the processing and forming of products with special shapes and performances. Thus, a large number of non-conventional extrusion process sprung up, which enriched the existing extrusion means and application fields. In this paper, the process principle, the technology characteristics and the application status of the special extrusion process were introduced in details, which had practical significance for improvement of additional values of extrusion process and development of expanding applications. |
