The entire process of making an international logistics sand table model

1、 Design Concept and Planning
Theme positioning: Select typical international logistics hub scenarios, including core nodes such as seaports, airports, bonded warehouses, and cross-border railways, to simulate the entire global flow of goods.
Proportional control: Using a 1:200 scale to ensure the coordinated presentation of large container ships and aircraft models within a limited space, while preserving the recognizability of operational details.
Dynamic design: Plan dynamic demonstration activities such as container lifting, AGV car transportation, and aircraft loading and unloading, and achieve basic motion functions through micro motors.
2、 Material selection and processing
Main structure:
Architectural complex: 3mm thick PVC board laser cutting and assembly, supplemented by acrylic board to show the reflective effect of glass curtain wall
Transportation tools: resin casting molding for ships and airplanes, metal etching for container truck chassis production
Ground system: epoxy resin mixed with quartz sand to make hardened pavement, fine copper wire embedded in the track to represent railway lines
Special components:
Openable container: magnetic design for easy loading and unloading demonstration
Dynamic lifting device: carbon fiber rod with micro pulley system simulating shore bridge operation
Lighting system: Fiber optic bundle simulates terminal lighting, LED light strips outline the outline of the port operation area
3、 Scene construction and coloring process
Layered coating technology:
Ship: First spray light gray primer, dry sweep deep gray to show metal wear, and finally dry sweep rust color to create a sense of aging
Aircraft: Mirror silver base, gradient blue for fuselage coating, black seepage line for reinforced cabin door structure
Architecture: Acrylic paint hand-painted brick wall texture, transparent blue expressing glass curtain wall reflection
Environmental Creation:
Water area: Transparent resin overlaid with blue paste, surface sprinkled with aluminum powder to simulate wave light
Airport runway: white gypsum powder mixed with fluorescent agent to make luminous runway lines
Yard: Arrange colored containers according to actual proportions, and use transfer printing technology to reproduce container numbers
Detail Enhancement:
Add miniature characters, vehicles, containers, and other proportional scenery
Using outdated techniques to depict equipment oil stains, tire marks, and other usage traces
The identification system uses real logistics company logo stickers
4、 Dynamic System Integration
Mechanical linkage:
Ship loading and unloading: Micro motors drive containers to move along the track
Airport conveyor belt: silicone conveyor belt circulating to simulate luggage transportation
Railway dispatch: Maglev technology enables container train movement
Intelligent control:
The central control system coordinates the timing of actions of each node
Touch screen selection of different logistics scene demonstration modes
Sound and light synchronous simulation of port operation environment sound effects
5、 Acceptance criteria
Proportional coordination: All components conform to a 1:200 proportional relationship
Functional integrity: Dynamic demonstration covering major logistics links
Detail restoration degree: More than 90% of the reviewers recognize the authenticity of the scene
