Aluminum is a lightweight and versatile material, but the choice of alloy has a big impact on its suitability for stamping. Hard alloys like 6000 series (e.g. EN AW-6082) may require higher pressing force but provide a durable product, while softer alloys such as 1000 and 3000 series are often more malleable and easier to work with.
A common objection is that stamping does not work for all aluminum alloysbut with the right choice of alloy and process, even difficult-to-machine aluminum grades can be punched efficiently.
To ensure precision and production speed, we use automatic presses with precise punching tools. But which parameters are crucial?
The pressing force depends on the sheet thickness, hole size and the material's tensile strength. Generally speaking:
Aluminium has a tendency to deform during stamping if the process parameters are not optimized. To minimize this, we use:
Some people believe that hydraulic punching machines are too slowHowever, these machines offer higher precision and less tool wear, which can save costs in the long run.
When choosing a method to process aluminum, many companies face the question of punching or laser cutting is the best option. Both methods have their advantages, but for large batches and high production rates, die-cutting is usually the most economical choice.
Laser cutting can be an excellent option for complex and low-volume productions where flexibility is crucial. But when it comes to cost-effective mass production of aluminum parts punching is usually the best solution.
To ensure accurate holes and minimal rework is required:
On Thor Ahlgren we use automatic presses with the capacity to process:
High wear and tear on tools → Use wear-resistant coatings and optimize lubrication.
Material deformation → Adjust pressing force and use support tools.
Slow production time → Automate and optimize the punching process.
Difficult to achieve the right tolerances → Invest in high-quality tools and careful process control.
Uncertainty about process choice → Consult experts to choose the right method and machine.
