| 英文摘要: |
| Rapid heat cycle molding (RHCM) is an emerging environmental friendly injection molding technology. Compared with the conventional injection molding technology, RHCM can improve the surface quality of the plastic parts, and the plastic products obtianed by RHCM have high gloss surface without weldline. RHCM can avoid the subsequent spraying in the process of conventional injection molding, thus reducing the production cost , simplifying the production process, shorten the production cycle, and the plastic parts produced by RHCM can be directly used for assembly. In this paper, the technology and the researches of RHCM are introduced in detail. In the aspect of technology, this paper introduces the process principle of RHCM technology, the methods of mold rapid heating/cooling and the design and manufacture of conformal heating/cooling channels. In the aspect of research, this paper summarizes the research of the numerical simulation of RHCM and introduces the influence mechanism of RHCM on improving products quality. In the end, this paper analyses the problems and development trends of RHCM. |
