Inner wood was integrated with hinges and latch
Reinforced material helps to strengthen the material. The latch and Hinge are placed on the embossing as the strength will be less at these positions. The reinforced material can be seen inner side of the hood where the metals are spot welded.
Hemming joints is created as shown in Figure and the joints are should be without any intersection
Thickening the inner hood as shown in Figure
Thickening of the outer hood as shown in Figure
The complete model of the hood is shown in Figure
Deep drawing

Deep drawing with a tool
Deep drawing with active energy
Deep drawing with active mean
