Application Fields
1.Aerospace
Aircraft wing spars, rocket bodies, and satellite supports adopt honeycomb sandwich structures (two thin face sheets + a central honeycomb core).
Maximize specific strength/specific stiffness to reduce every gram of weight.
2.Automotive Industry
The A/B pillars of vehicle bodies and chassis longitudinal beams adopt hollow variable-section structures formed by roll forming of high-strength steel.
Efficiently absorb energy during collisions to protect the safety of the passenger compartment.
3.Construction Engineering
The main girders of large bridges and the columns of skyscrapers often adopt box-shaped sections (large hollow rectangular steel beams).
Achieve super strong bending and torsion resistance with minimal self-weight.
4.Sports Equipment
High-end bicycle frames, golf club shafts, and badminton racket frames widely use hollow tubes rolled from carbon fiber composite materials.
Achieve ultimate lightweight performance and efficient force transmission.
5.Everyday Products
Drone arms, metal furniture brackets, and aluminum alloy door and window profiles.
Ensure sufficient rigidity while controlling costs and weight.
Manufacturing Technology
1.Traditional Manufacturing
Extrusion/Drawing Forming: Suitable for metals (such as aluminum alloy) and plastics, it can produce hollow long profiles with various complex cross-sections.
Welding/Assembly: Welding plates into box-shaped or tubular structures, which is widely used in construction and heavy machinery.
2.Advanced Manufacturing and Design
3D Printing/Additive Manufacturing: This is a revolutionary technology for achieving optimized hollow structures. It can easily produce internal lattice structures or bionic sponge structures that are impossible to achieve with traditional methods, minimizing material usage while ensuring performance.
Topology Optimization: This is an advanced design method. Given a design space and stress conditions, computer algorithms will "tell" you where materials should be distributed. The optimization results are often complex and efficient organic-shaped hollow structures, making it the perfect pre-design for 3D printing.
