Criteria	Existing technology (aluminum cold forming)	Developed technology (aluminum hybrid-warm drawing)
Features	- Cold forming of aluminum plate - Because the elongation percentage of aluminum is not good at room temperature, it is possible to produce only simple products - Most of the forming in a small amount	- After heating aluminum plates to a high temperature, transfer them to the mold to form - No deterioration of aluminum properties by forming at a warm temperature (200~400℃) - Both forming and drawing forming for a large amount is possible
Advantages	- Low price - simple mold structure	- Forming of complicated shapes is possible - Easy post-deformation control with mold Quenching
Disadvantages	- Forming of complicated shapes is possible - Easy post-deformation control with mold Quenching	- Expensive - Rather complicated mold structure
Application	- General vehicles	- Luxury vehicles, high-performance vehicles, hybrid vehicles, e-vehicles, fuel cell vehicles, tuning vehicles, etc.
