Based on the structure and size.
1. If 0mm-20mm, the overall wall thickness can't be less than 1.5mm, for the transition part, it can't be less than 1.2mm.
2. If 20mm-40mm, the overall wall thickness can't be less than 2.0mm,for the transition part, it can't be less than 1.5mm.
3. If 40mm-60mm, the overall wall thickness can't be less than 2.5mm,for the transition part, it can't be less than 1.8mm.
4.If 60mm-80mm, the overall wall thickness can't be less than 3.0mm,for the transition part, it can't be less than 2.2mm.
5. For the above, the overall wall thickness can't be above 5mm, for the specific area, it would be set based on the detailed structure.
