Mobile phone design notes [pic] Mobile phone design notes The structural design of mobile phone products is the key to realizing product functions. This not only needs to be coordinated with the product appearance, but also needs to consider various aspects such as subsequent production assembly, painting, spraying, mold design and manufacturing. The body structure design of mobile phone products involves a wide range of knowledge, mainly including: 1. Material selection; 2. Surface treatment; 3. Processing methods; 4. Packaging and decoration; The use of these factors directly affects the life and appearance of mobile phone products. It can be said that the level of the designer determines the vitality and grade of the product. High-end products are not necessarily high-cost. Using low-cost to design high-end products is a reflection of the designer\'s high level and high quality. I mainly want to talk about the first two items, and the last two items will be discussed later. 1. It is necessary to evaluate whether the shape design is reasonable and reliable, including the manufacturing method, the mold release direction, mold release angle, core pulling, structural strength, circuit installation (cooperation with electronic engineers), etc. of the plastic parts. 2. Determine whether the manufacturing process can be achieved according to the shape requirements. Including mold manufacturing, product assembly, shell spraying, silk screen printing, material selection, and the supply of parts to be purchased. 3. Determine whether the product function can be realized and whether the user can use it best. 4. Carry out specific structural design and determine the manufacturing process of each part. Pay attention to the structural strength, installation positioning, fastening method, product variation, component installation positioning, safety requirements of the plastic parts, and determine the best assembly route. 5. The structural design should minimize the difficulty of mold design and manufacturing, improve the efficiency of injection molding production, and minimize mold cost and production cost. 6. Determine the production process and testing methods of the entire product to ensure product reliability. I. Ways to select plastic materials Understanding the performance of engineering plastics Plastics sometimes behave strangely during molding. The answer to one molding problem may be completely different from another molding problem. This may be because these examples involve two essentially different plastic resins. This article will discuss the properties of these materials and the differences between various materials to enhance the understanding of the mechanisms in the injection molding process. (1) Characteristics of crystalline polymers Many people are familiar with crystals such as table salt, sugar, quartz, minerals and metals, and of course ice. These solid substances have the characteristics of orderly molecular arrangement and dense accumulation. Others are solid substances that do not form regular crystal arrangements. It...
