模具的構造基礎
塑膠的射出成形模具要能被鎖定於指定的機台，接受加溫溶化的塑膠，讓它很容易被擠壓入模內而成形。既要飽模，又不發生毛邊。等待冷卻定形之後，開模，使成品能退出模具。而能長期的重覆使用，是塑膠射出成形模具的構造基礎。

Alessandro Volta fue un físico e inventor italiano que vivió entre 1745 y 1827. Es conocido por inventar la primera celda voltaica o pila eléctrica, que producía una corriente eléctrica continua a través de una reacción electroquímica entre dos metales diferentes y un electrolito líquido. Su invención de la pila voltaica marcó el comienzo de la era de la electricidad y sentó las bases para el desarrollo de la batería moderna.Rich Media

The document discusses how Cohn & Wolfe, a public relations firm, is not effectively leveraging digital and social media strategies to build their brand online, despite claiming it as a core competency. It analyzes their search engine rankings and web presence when searched for terms like "public relations", "brand marketing", and "digital marketing" and finds they do not rank within the top 50 results. It suggests Cohn & Wolfe could improve their online presence and rankings by developing more robust use of rich media strategies like microsites, email campaigns, in-page interactive content, emerging media, social networks, and live streaming video to better promote their capabilities to potential clients.
