Industrial Plant Site Sand Table Model Production Plan
I. Project Background

A sand table model of the plant site was produced for a chemical company, requiring the complete presentation of 23 functional areas, including the tank farm, pipe rack system, and central control room, with a scene reproduction rate of 90%.
II. Core Production Processes
Terrain Construction
Terrain elevation differences are created using layered carved foam boards
Surface texture is formed using a mixture of plaster and quartz sand
After hardening, a primer is sprayed to enhance adhesion
Building Construction
Main factory buildings: Acrylic laser-cut panels with etched patterns
Steel structure: Assembled using micro-welding of brass tubes
Glass curtain walls: Vacuum-coated laminated process
Equipment Reproduction
Reactors: 3D-printed resin parts with manual polishing
Pipeline system: Soft PVC pipes formed by heat bending
Instrument panels: Screen printing technology to reproduce the operational interface
III. Material Presentation
Metal texture
Tank area uses electroplated silver as a base coat
Rust effects achieved through layered application of mineral pigments
Final coating with a matte protective layer
Special effects
Liquid medium: Epoxy resin colored and poured
Steam pipes: Cotton fiber electrostatic flocking
Lighting system: Micro-LEDs embedded and installed
4. Coating System
Base color matched using industrial-grade color charts
Oil stains rendered using oil paint blending
Final application of UV-resistant protective coating
5. Quality Control Standards
Aerial photography comparison error controlled within 3%
All removable components pass durability testing
Passes 72-hour constant temperature and humidity environmental testing
