JBM Group Tool & DIE Maker Interview Questions, Process, and Tips

Wrinkles occur due to excessive stress on the material during the forming process.

• Wrinkles are caused by compressive stresses in the material.

• They occur when the material is stretched or bent too much in a localized area.

• Factors that contribute to wrinkles include material thickness, bend radius, and lubrication.

• Wrinkles can be prevented by adjusting the forming process parameters or using a different material.
