在制造业中，通过修理将设备恢复到原有的设定状态，是维护技术系统的任务之一。更新准备报废的或已经报废的机械设备也是其目标。这里，涉及到一个再生利用的方式，其意义多半是被低估了。一台机器经过修理或现代化之后可重新使用，这相对购置新机器而言是一个费用合理和技术上等价的方案，但是人们对此显而易见的优点还未有足够的认识。为了尽可能缩短一个产品的再循环周期，以达到重新取得利用如同一种新产品的效果，这里引用了“再制造”的概念。 In the manufacturing industry, repairing the equipment back into its original configuration is one of the tasks of maintaining the technical system. It is also the goal to update the prepared or scrapped machinery and equipment. Here, involving a way of recycling, the meaning is mostly underestimated. A machine that can be reused after being repaired or modernized is a cost-effective and technically equivalent solution for acquiring new machines, but there is not enough awareness of the obvious advantages. In order to shorten the recycling cycle of a product as much as possible to achieve the same effect as a new product, the concept of “remanufacturing” is cited here.
