         most 近, micro upper in understanding is new machine 荣耀9X Pro时, rise drop front 置摄像头 is “ plastics ”做, about/regarding is machine quality 讨论.

        普通人 for new type material 认知, plastics inner 人士想象 that 么乐观.

        实质 upper this about/regarding 荣耀9X摄像头 use “ plastics ”材质 new parts, in this plastics process speed development 时代, market, manufacturing and and other different color in lower different reaction.

         although 互联网 and new upper has 刻意引导之嫌, 但吃瓜群众们 reaction, 体现 民众 for used as waste bag “ plastics material ”, in use in machine 摄像头 upper understanding and 不信任.

        实际情况 is, plastics is very large product type. through 摄像头 is plastics 材质, product good bad, is types non 常原始 观念.

        因 is, remove day active general purpose plastics, also has large type is engineering plastics. 此次事 parts in, 荣耀9X Pro front 置摄像头, use belongs to engineering plastics in industrial nylon plastics.

        当 lower, engineering plastics can substitute/replace metal ratio ratio is. from automotive, construction to high-speed rail aerospace device, has engineering plastics 影子.

         ratio 如, electrical 风扇 扇叶早 already from metal formed plastics 材质, 600千瓦 风 force electrical machine long 约20米, filling is plastics 材质. is plastics quality more light, use more good.

         from design 端看, engineering plastics full table/sheet quality has issues. this type of material cost can 控, weight light, strong/high degree, wear resistant 也都远 ultra- general purpose plastics. 配 alloy 材质 承 heavy, effect/influence machine use lifespan.

         versus 反, manufacturing for new material application, very more also can reduce cost, improves quality, to market belt/tape more good product and more price.

         can 说, 不论网络 large V们 how use “ plastics ” this 样 词汇刺激 market 神经, 试图 人们 belt/tape to upper 世纪进行“认知返祖”, product and technology 迭代永不停歇.

         has in industrial 不发达 year 代, 人们才会坚定 认 is 摄像头 use plastics 材质不 is good product, 就像“钢盆”, “搪瓷碗” is that year 代才会出现 特 has 词汇.

        互联网 upper property or can 一时刺激消费者, machine use true 实体验才会迭代出 positive 确 认知.

        一款 product, material multiple more 样, large more parts 普通消费者闻 未闻, 同样也不 can use “材 material ” 判断 product quality.

        今天 market is: “ good 空调格 force 造” and “荣耀5X挡子 elastic ”, has use material this product, this is property. different Brand R&D design, production process and product standards, 才决定 消费者拿 to product quality.

         analysis use plastics 做摄像头 华 is machine, again also has which upper 天入 神奇 plastics, 出现并 in 改变 人们 生 active.

         below/following is waste plastics new 观察（ID:CSPA-SMS）整理 has plastics separation dry 货, 以飨读者.
