Modeling and analysis of multi-shot injection molding of Blu-ray objective lens
摘要： The Blu-ray objective lens is one of the electronic parts that has an important role in data storage in such a way that its production requires a high level of accuracy. One way to produce the Blu-ray objective lens is by means of a micro-injection molding technique. We investigated the effect of insert part in a multi-shot injection molding on the shrinkage after the process of injection. An aspherical shape is made for the insert part of the Blu-ray objective lens, then compared with single-shot injection molding. Zemax software was used to design the Blu-ray objective lens, while Moldex3D software was applied to analyze the flow of material into the mold during the injection process. The Taguchi method was used to determine the best parameters to obtain the minimum shrinkage values of the injection processes of both multi-shot injection and single-shot injection molding techniques. Based on the observations, it is clearly evident that the multi-shot injection molding process has a lower displacement value compared to the single-shot injection molding, namely, 0.0161 mm compared to 0.0550 mm and also the multi-shot injection can save the cooling time 5 seconds faster than single-shot injection molding. So, this can favorably improve the production of the injection process for the material in the form of the micro part.

A solid (state) success
摘要： James McKenzie reflects on the impact of the solid-state laser, a device in its infancy when it became the subject of one of the first articles in Physics World. The article discusses the evolution of solid-state lasers from their early days to their widespread use in various applications such as compact discs, DVDs, Blu-ray discs, and optical communications. It also speculates on the future of solid-state lasers and their continued relevance in emerging technologies.

21.1: <i>Invited Paper:</i> Development Trend of LCD Technology
摘要： Recent strong requirement of higher image quality for LCDs are more improvement of than ever along with transmission technologies such as 8K TV, 5G, and so on. This paper introduces BOE's development trend of LCDs including technical element, and design trend. The impressive influences of LCD in people's modern digital live force panel makers such as BOE to ponder on the development of LCD technology. How should the LCD become more vivid and more accepted by the user? When the 8K display and the age of 5G are coming, how should LCD undertake its historical responsibility in the ecosystem of the Internet of things? The development trend of LCD through technical elements and design elements are summarized below. LCD will become more and more magnificent.
