Material Related Design with Tailor Rolled Products - Automobile manufacturing - Shenzhen Hongbai Technology Industrial Co., Ltd.

Idea:
 Lightweight parts with load and function-optimized
material usage
Implementation of Idea / Targets / Benefits:
 Flexible Cold-Rolling Process
 Flat material with repeated, varying thickness runs
and harmonious transition zones
 An increased number of thickness zones for an
optimized TRB solution results in minimal
lightweight cost
Targets / Benefits:
 Weight Reduction
 Part Integration
 Functional Improvement

Objective
 Weight and function optimization
Innovation
 Welded assembly body structure with
single-layered flanges in combination
with TRB ®
Advantages
 Weight reduction of up to 16%
 Improved connectivity to body
structure due to single-layered flange
 Highly efficient solution due to
building closed section (like tubes)
while improving performance
Status
 Serial development

Objective
 Weight and function optimization
Innovation
 Introducing a slim foot design to get
a parallel nesting within the max. coil
width of TRB ®
Advantages
 Weight reduction of up to 17%
 High material utilization
 Independent thickness run without
requiring a symmetry line
Status
 In serial production soon

Mubea Flange Technology
 Weight reduction of up to 16%
