The bottom compression-drawing was introduced for boss deforming.

Its operation principle is based on the theories of flocculation sediment,shallow layer sediment and deeply condensation.

The application of several new techniques,including hydraulic pressure drawing,inside tube high pressure forming and hot forming,in the shaping of automotive stamping parts were presented.

This paper presents the investigation into the forming process of the one path deep drawing spinning of cups, which mainly focuses on the effect of the roller shape with the two arc working face on the forming process.
