Metal sensor deep drawn stamping housing

1. Elastic deformation stage. In this case, the strain is equal to σ/E, and the relationship between strain and stress is linear. At this stage, the strain ε continues to occur, but the stress σ does not increase linearly with the strain, but fluctuates up and down in an interval, the lower limit of which is usually defined as yield strength 3. Hardening stage. At this stage, the material is hardened by cold working, and the small strain can cause the stress to rise sharply, and the stress reaches the maximum at a certain point, which is called tensile strength 4. Necking stage. At this stage, deformation can continue to occur without too much stress, and the material will shrink at the same time. When the necking occurs to a certain extent, the material will fracture

Drawing techniques are extremely complex, and the following important factors should be considered in practice

1)selection of materials

2)Selection of lubricating oil
