风管安装为什么要采用预制加工技术？
Why should Prefabrication Technology be adopted for air duct installation?
不受施工场地的局限
Not limited by the construction site
工厂化预制将大量材料原材料加工任务搬离了施工现场，可以减少加工场地对现场的占用及依赖。
Factory prefabrication removes a large number of raw material processing tasks from the construction site, which can reduce the occupation and dependence of the processing site on the site.
缩短现场施工工期
Shorten the construction period on site
工厂化预制将部分施工任务型线  流水槽模具 景观石 检查井钢模具 保定通风管道 重庆窗帘 隔离墩模具 保定保洁公司搬离了施工现场，在现场机电工作面还没有的时候预制即可提前开始，并且大幅度提高构件制造的生产效率。
Factory prefabrication moves some construction tasks away from the construction site. Prefabrication can be started in advance before the on-site electromechanical working face, and greatly improves the production efficiency of component manufacturing.
减少材料损耗
Reduce material loss
在预制加工中心，风管集中加工，自始至终由一个作业组负责下料，做到“量体取材”，避免了现场材料乱截现、大材小用等现象。
In the prefabrication and processing center, the air duct is processed in a centralized manner, and one operation group is responsible for blanking from beginning to end, so as to achieve "measuring and taking materials", so as to avoid the phenomenon of random cutting and overuse of on-site materials.
