Hot form stamping is the process of forming metal using extreme heat. The metal, boron steel, is heated to over 1700 degrees Fahrenheit and quenched in the die itself. The result is a high-strength, lightweight steel part.
One of the main advantages of a hot metal stamped part is its high tensile strength, which ranges from about 50 kilo pounds per square inch (KSI) to about 200 KSI once the process is complete. Hot stamping also allows you to form complex parts all at once, meaning less welding or other joining measures. Parts produced from this method also do not experience spring-back and warping in the way other high-strength steel formed parts tend to. Unfortunately, the hardened part is difficult to cut, making post-formation trimming and cutting a challenge. You will generally need a powerful laser for these processes.
To perform Hot form stamping, you need several pieces of equipment, including:
- A heating system capable of heating the metal to the necessary temperature.
- An adequate cooling system.
- An automated handing system, as the completed part will initially be far too hot to touch.
- Tooling materials that are highly resistant to thermal shock.
- A hydraulic/servo press with dwell capabilities.
Your stamping press system obviously must conform to all safety requirements.
