Transparent style filters cover for observation , such as a round of excessive dust may be unloaded filtering carcasses and body covered , removed a filter to remove dust and impurities , the cleansing is very convenient 透明式的过滤器罩便于观察，如出现罩内尘埃过多，可卸下过滤壳和罩盖，取出过滤网，清除尘埃和杂质，清洗非常方便。
But in automobile body cover ramming process the technical difficulty is the ramming craft formulation and the mold designs . reasonable ramming craft and high grade mold , not only can improve the pressing part quality and productivity , also reduces the waste product rate 而在车身覆盖件的冲压过程中其技术难点是冲压工艺的制定和模具设计,合理的冲压工艺及高质量的模具,不但能提高冲压件质量,还能提高生产率,降低废品率。
Moreover , the paper compares the role of industrial designers and engineers played in the process of manufacture to explain the causes of perceptual gaps between them . this thesis also introduces the crucial manufacturing technology , the sheet metal ? punching , with a specific case of automobile body cover panel for the heavy trucks 最后,论文通过介绍制造业中最重要的板材成型? ?金属板材冲压成型,结合卡车和乘用车的车身金属覆盖件的制造加工特点和作者本人的设计实践,探讨如何协调设计与制造来完成汽车造型设计。
