Figure 1 shows a temperature-sensitive head card punching piece, which is unfolded as shown in Figure 2, with a material of 2A02 and a thickness of 0.5 mm. The part has a compact structure and needs to be formed by three-sided bending. The part requires a smooth and smooth surface without warpage, wrinkles, cracks and the like, and the mold should be designed to be continuously punched and bent. If the feeding direction is selected improperly in the design, it is easy to cause irregularities in the shape of the punched out parts, large burrs, and poor size.
Asphalt Tile
Asphalt roof tiles is a type of roof shingle that uses asphalt for waterproofing. It is one of the most widely used roofing covers in North America because it has a relatively inexpensive up-front cost and is fairly simple to install.
Two types of base materials are used to make asphalt tile, organic and fiberglass. Both are made in a similar manner, with an asphalt-saturated base covered on one or both sides with asphalt or modified-asphalt, the exposed surface impregnated with slate, schist, quartz, vitrified brick, stone,or ceramic granules, and the under-side treated with sand, talc or mica to prevent shingles from sticking to one-another before use.
