Suitcase

A suitcase is a complex assembly that must withstand extreme physical stress while maintaining a premium aesthetic. Prototyping is a critical step for: Structural Integrity Testing: Conducting drop tests and treadmill tests on physical prototypes to ensure the shell and corners don't crack under impact. Mechanism Validation: Verifying the telescopic handle's smooth extension and the 360° rotation of the spinner wheels under full load. Ergonomic Evaluation: Testing the handle grip comfort, zipper accessibility, and internal compartment layout for the end-user.

Lock & Security Testing: Refining the integration of TSA-approved locks into the frame to ensure seamless operation before opening expensive steel molds. Weight Optimization: Evaluating different wall thicknesses to achieve the perfect balance between a lightweight design and heavy-duty durability. Texture & Color Finalization: Creating high-fidelity "Master Samples" with specific grain textures (e.g., carbon fiber, diamond, or leather patterns) to finalize the visual identity.

PC (Polycarbonate): Used for high-end "hard-shell" prototypes due to its incredible impact resistance and transparency (if required). ABS / PC+ABS: The standard for durable, cost-effective shells that require specific surface textures. Aluminum 6061 / 7075: Used for the telescopic tubes and reinforced corner protectors or frames. TPU / TPE: Ideal for the "soft-touch" handles and the rubberized tread on silent spinner wheels. Nylon (PA66): Used for heavy-duty hinges, latches, and internal structural brackets.

Large-Scale CNC Machining: Utilizing large-travel CNC centers to machine full-size suitcase halves from solid blocks of ABS or PC. Vacuum Casting (Small Batch): Producing sets of matching luggage (Carry-on, Check-in) for marketing photography or trade show displays. Surface Texture Replication: Using Laser Etching or specialized Texture Painting to mimic the look and feel of spark-eroded or chemically etched mold surfaces. Anodizing & Electroplating: Providing a premium metallic finish for aluminum frames, logos, and hardware components.

Seamless Closure: Maintaining tight tolerances of ±0.1mm along the zipper track or aluminum frame to ensure the suitcase closes perfectly without misalignment. Load-Bearing Performance: Our functional prototypes are built to support standard travel weights, allowing for real-world testing of handles and wheels. Precision Hardware Integration: Ensuring that locks, hinges, and handles are recessed perfectly into the shell for a sleek, professional look.
