塑料外壳的比强度
从工程力学角度,某些塑料外壳的比强度(强度与重量的比值)甚至比铝合金还高,只要是背壳略微厚一点,其强度比之铝合金毫不逊色,足以满足消费者的日常使用,毕竟这些产品在消费者手中不是作为受力件使用的。
From the perspective of engineering mechanics, the specific strength (the ratio of strength to weight) of some plastic shells is even higher than that of aluminum alloy. As long as the back shell is slightly thicker, its strength is not inferior to that of aluminum alloy, which is enough to meet the daily use of consumers. After all, these products are not used as stress parts in the hands of consumers.
同质化产品越来越多的今天,一部产品的外观无疑是吸引人眼球最直接方式。而塑料材质在观感上确实不如金属材料,总会给人一种廉价的感觉,这是硬伤。于是厂商也想了许多办法,比如在塑料外壳上使用金属拉丝纹路,看上去着实有着不小的提升,但是塑料始终是塑料,骗得了眼镜却骗不了手。还有就是触感,塑料与金属的入手感觉决然是不同的
Today, with more and more homogeneous products, the appearance of a product is undoubtedly the most direct way to attract people's attention. Plastic materials are not as good as metal materials in appearance. They always give people a sense of cheapness, which is a hard injury. Therefore, the manufacturer also thought of many ways, such as using metal wire drawing lines on the plastic shell, which seems to have a great improvement. However, plastic is always plastic, but it can't deceive glasses. There is also the feeling of touch. The starting feeling of plastic and metal is definitely different
