Industrial Sand Table Model Production

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
