Progressive Drawing Die Technology

Progressive drawing is a precision forming process used to shape flat metal sheets into three-dimensional components. As the metal blank is formed into the die cavity, it must flow smoothly and under control to achieve the desired geometry without defects.

Material Flow Control
The material flow is managed by applying pressure to the blank and using lubrication either on the die or the blank surface. If the material flows too easily, it can lead to wrinkling. To prevent this, increased pressure or reduced lubrication is used to restrain the material flow, causing the metal to stretch or thin.

However, excessive pressure can lead to over-thinning of the material, resulting in cracks or part failure. Thus, deep drawing is a delicate balance between wrinkling and tearing, requiring careful engineering and process control to produce high-quality parts.

Design Guidelines

• A good starting point for die design is using a radius equal to three times the material thickness.

• If cracking occurs, it usually indicates that the tool has been machined metal-safe, which allows for increasing the radius to reduce forming stress.

• Some part specifications may call for a tight radius under the flange. Depending on the application, this may be achieved in a single draw, rather than requiring multiple draws to gradually form the final shape.

Progressive drawing is both a science and an art—requiring experience, precision tooling, and accurate simulation to ensure consistent, defect-free results.
