随着我国汽车工业的发展,各种保温车、箱式车、冷藏车的需要量急剧增加。此类车的外蒙皮大多压制成瓦楞权形状,以提高车箱刚度和外观美。我厂生产的箱式车外蒙皮瓦楞板如图1所示。 With the development of China’s automobile industry, the demand for all kinds of insulation vehicles, box-type vehicles and refrigerated trucks has sharply increased. Most of the outer skin of these vehicles pressed into a corrugated shape, to enhance the rigidity and appearance of the United States. I plant the box car outside the corrugated board shown in Figure 1.
