One-piece molded rake from red-hot steel plate - Video

The real highlight isn't "pressing down a rake," but the plastic flow of red-hot steel within the mold. The steel plate, heated to a red-hot state, is fed into the press. The instant the mold closes, the material undergoes plastic deformation under high temperature and pressure. The originally flat plate is compressed laterally and stretched longitudinally, the metal being extruded along the mold cavity to form rake teeth. You can clearly see the teeth lengthening and thinning after being pressed down. This isn't welding, nor cutting and assembling; it's a single, integral forging process. The material volume is essentially conserved, with compression resulting in elongation. The internal fiber flow lines are continuous, with no weld seams or breaks. The structural strength comes from overall deformation, not from connecting parts. The entire process takes only a few seconds, but it involves a combination of mold design, material plasticity, and stress control. Essentially, it's about reshaping the steel under instantaneous high pressure, rather than simply flattening iron.
