Working With Metal Stamping Components: Remember These Details

Precision metal processing and various other elements and design safeguards are essential when working with automotive metal stamping parts.

Machining Metal To Exacting Specifications

Depending on the stamping process, additional operations like burring, tapping, hinge installation, and punching may be performed after stamping to improve the product’s functionality and safety.

After stamping, the workpiece will have small shards of the cutting material left on it, which must be removed to get a smooth finish. Burrs may be ground off sharp edges by grinding or twisted to generate smooth edges; burrs can be directed to internal folds to hide them from view.

Measures Should Be Taken Throughout The Design Process.

Narrow designs should be avoided in stamping items since they may be more prone to distortion and impact the perception of the end product’s quality. Instead, the design should use preexisting molds and conventional forms whenever practical. Customizing the stamping die adds to the original die cost. Avoiding sharp internal and exterior corners serves as a primary design goal for stamping goods to lessen the likelihood of big burrs on sharp edges that must be removed during secondary treatment.

The sharper the corner, the more stress is concentrated there, and the greater the chance that the following section would fracture or break from long-term usage. Consider the edges or folds of material consumption and any additional materials, and the available dimensions of sheet metal or blank will dictate the total dimensions of the completed product. Further, the second phase in processing big items may include many procedures, such as establishing and mechanical connection.

When doing punching tasks, it is important to think about both the direction and nature of the punches. Since holes are typically punched in a single direction, any jagged edges created by the punching needle should be on the same side of the material as the hole.

Thus, the look may be modified to conceal these edges, protecting the product’s employees and consumers from harm. The raw materials’ thickness should be reflected in the punching characteristics, and the punching size should be at least twice as large as the thickness.

Sheet metal components have a minimum bending radius equal to the thickness of the metal itself, regardless of the bending degree. However, bending too tiny components may be challenging and lead to stress and poor quality in the final result.

Positioning, tolerance, and precision may be better assured while drilling holes if they are all done simultaneously. At the same time, the minimum hole spacing must be at least twice the thickness of the material, and the diameter must be at least as much as the thickness of the material.
