Project Background
A new energy technology company commissioned the production of a 1:50 scale lithium battery production line sand table model, requiring a complete display of the entire process from raw material pretreatment to finished product packaging, with a focus on the process details of core procedures such as electrode preparation and cell assembly.
Core Production Processes
1. Frame Construction
5mm acrylic sheets were laser-cut and formed, with a mortise-and-tenon joint structure enabling glue-free assembly.
Equipment bases were CNC-machined from ABS sheets to ensure load-bearing stability.
The conveyor belt system used 0.3mm copper wire to simulate the actual movement trajectory of conveyor chain links.
2. Equipment Reproduction
The coating machine uses transparent resin 3D printing to present the roller structure.
The stacking machine uses magnetic movable parts to demonstrate material handling actions.
The liquid injection station is equipped with miniature LED lights to simulate vacuum environment warnings.
3. Pipeline System
The main air pipeline uses silicone tubing with embedded fiber optics to create fluid dynamics.
The cable tray is assembled using etched copper plates following the actual routing.
Cooling pipes are cast using gradient blue transparent resin
Special material applications
Metal texture: Electrode foil sheets are treated with aluminum foil embossing
Transparency effect: Electrolyte storage tanks use crystal resin with suspended bubbles
Safety markings: Hazardous chemical areas are marked with glow-in-the-dark paint
Floor texture: Epoxy resin mixed with quartz sand creates a slip-resistant floor
Post-processing techniques
1. Layered coloring
Primer: Automotive-grade metallic paint to enhance adhesion
Main color: Industrial equipment-specific matte paint (Pantone 428C standard color)
Aging treatment: Dry brushing technique to highlight equipment usage traces
2. Dynamic effects
Conveyor belts equipped with miniature speed-reducing motors (3 rpm)
Robotic arm movements triggered by magnetic control switches
Temperature control dashboard with variable resistor-regulated display
3. Environmental creation
Adjustable-angle spotlight system installed on the ceiling
Safety warning sound module hidden beneath the viewing platform
Custom acrylic dust cover integrated with static elimination device
