Photovoltaic building sand table model production, customized manufacturer of new energy storage models

Case study of photovoltaic building sand table model production

The birth of the photovoltaic building sand table model in our factory's production workshop is the result of the collaboration of material selection, process polishing, and post restoration. From drawings to finished products, anchor the goal of "90% restoration" at every step, making the model a "miniature mirror" of the real scene.

1、 Material selection: Accurately match the texture of the scene

The core materials of the model revolve around "photovoltaic buildings+new energy facilities":

Main body of the building: Environmentally friendly PVC sheets are selected, and the roof and walls are precisely shaped through laser cutting to restore the building outline;

Photovoltaic modules: customized blue acrylic panels, simulating the regular arrangement and texture of photovoltaic panels;

New energy facilities: ABS engineering plastics are used for charging piles, energy storage cabinets, etc., and complex structures (such as charging ports for charging piles and heat dissipation holes for energy storage cabinets) are achieved through 3D printing;

Environmental details: Grey PVC boards are used for roads, simulated lawns are selected for vegetation, and resin+flocking technology is used for trees to make the green plant layers more natural;

Lighting system: Built in LED light strip, simulating building lighting, photovoltaic panel reflection and other light and shadow effects.

2、 Production process: Layered promotion of reduction degree

The production process is divided into three steps: "structure construction → detail assembly → scene fusion", each step serving the restoration degree:

Structural construction:

First, use PVC boards to splice the main framework of the building, ensuring that the roof slope and wall proportions are consistent with the real building; The photovoltaic panels are fixed with acrylic sheets and adhesives, simulating the "staggered and orderly" installation in real life.

Detail assembly:

Charging station: ABS plastic prints out the charging port, display screen, and other details of the charging station, and then paints them for color correction;

Energy storage cabinet: resin mold is used to make the cabinet body, and the flocking process is used to restore the texture of the cabinet body;

Road: After cutting the PVC board, use sandpaper to polish the rough texture of the "asphalt pavement".

Scene fusion:

The model is surrounded by simulated lawns, with trees arranged in a staggered pattern of height to simulate the green hierarchy of a real factory area; At the junction between the road and the building, fix it with glue to avoid a "floating feeling".

3、 Post processing: The 'Real Magic' of Coloring and Light and Shadow

The later stage is the key to making the model "live". Through three steps of coloring, lighting, and detail completion, the model can be transformed from a "model" to a "scene":

Coloring process:

The main body of the building is painted with matte paint (mainly white, simulating the texture of the building's exterior walls); Blue paint is used for photovoltaic panels (layered painting to restore the gradient of light and dark of the photovoltaic panels); Metal colored paint (silver gray, dark gray) is used for charging piles and energy storage cabinets to simulate the coldness of industrial equipment.

Lighting debugging:

LED light strips are embedded inside the building and simulate "night lighting" when powered on; Add small light beads under the photovoltaic panel to simulate "daytime reflection"; Micro LED lights are used for road lighting, allowing the details of the scene to be online day and night.

Detail completion:

Use a fountain pen to spray "wall texture" onto the exterior walls of buildings; Use a fine pen to mark the "installation frame" on the edge of the photovoltaic panel; Trees use flocking glue to complete the "details of branches and leaves", making green plants more realistic.

4、 The 'secret' with a restoration rate of 90%

In production, we always anchor the "miniature version of the real scene":

Building proportion: strictly reduce the "length, width, and height" of the real building to ensure coordinated proportions;

Facility details: The charging port of the charging station and the heat dissipation hole of the energy storage cabinet are all "one-to-one" restored to the real equipment;

Environmental atmosphere: The density of the lawn, the height of the trees, and even the "light and shadow angles" of the street lamps are all based on the real scene of the factory area.
