This book summarizes the advanced manufacturing technology of original innovations in hot stamping of lightweight car body.
... Cold-stamped door impact beams made of TS1180 MPa grade cold-rolled high strength steel have been developed. The newly developed parts achieved both weight and cost reductions compared to former hot-stamped parts. Cold-stamping was ...
... cold stamping method. To solve this problem, hot stamping technology is being developed rapidly. Hot stamping or hot forming combines the heat treatment and cold stamping to produce stamping parts whose strength is greater than 1,000 ...
... cold stamping [8–11] in the most efficient way. Bulk cold stamping with cold stamping machines, as well as rotary and rotary conveyor lines, is successfully used to produce a wide range of generic parts (fasteners, sleeves, etc ...
... stamping say two or three valves . The compression test re- sults are borne out , therefore , by workshop practice , High tungsten steels are useful in certain classes of cold stamping where great density is required in the die ...
... cold stamping; (b) traditional hot stamping; (c) novel hot stamping. The results of the tensile tests are shown in Table 3. The tensile strength of novel hot stamping process can reach 597 MPa, which is a bit lower than cold stamping ...
... stamping lies in the potential for reducing the amount of forming stages that are required in cold stamping , as well as decreasing the number of presses and forming tools . For example , only one stage is required to form a B - pillar ...

... cold - stamping method . Moreover , the hot stamping is a better product than the cold stamping , as it follows faithfully every contour of the die and retains its shape , having no tendency to " spring back " from form . The skill and ...
