三种不同类型注塑模具的特点与发展现状

Characteristics and Development Status of Three Different Types of Injection Molds

分析了大型注塑、精密注塑、薄壁注塑的特点,发现由于其注塑工艺不同,对模具的要求也不相同。介绍了大型注塑模具、精密注塑模具、薄壁注塑模具的特点和国内研究现状,指出我国在注塑模具的设计理念、制造工艺等方面与国外还存在很大的差距,需要进一步创新。

The characteristics of large-scale injection molding, precision injection molding and thin-wall injection molding were analyzed. It was found that due to their different plastic injection molding process, the requests to the mold were also different. While the characteristics and domestic research status of large-scale injection molding, precision injection molding and thin-wall injection molding were introduced^Pointing out that China has big gap with foreign in the injection mold design, manufacturing processes and other aspects.Therefore further innovation is needed.
