Case study on the production of a sand table model for the integrated charging station of Zhihui Guang storage and charging

This project is a sand table model showcasing the integration of smart light storage and charging scenarios, focusing on the linkage presentation of charging pile clusters, photovoltaic energy storage, and urban supporting facilities. It accurately replicates the spatial logic and technological texture of real operating scenarios, ultimately achieving a 90% realistic reproduction degree and becoming the core interactive carrier for enterprises to showcase new energy solutions.

In material selection, we adhere to the core principle of "technological sense+stable structure". The sand table base is made of high-density board to ensure overall load-bearing and flatness; The main body of the charging station is made of matte ABS and aluminum alloy profiles, restoring the tough texture of industrial equipment; The photovoltaic panel adopts high transparency acrylic and blue simulated photovoltaic film to simulate the visual effect of real photovoltaic modules; The building and supporting facilities are made of 3D printed photosensitive resin, which meets the requirements of fine modeling and lightweight. The transparent protective structure and display panel use highly transparent acrylic material, which not only ensures the visibility of the internal structure, but also conveys a sense of technological transparency; The circuit and lighting module use flexible LED light strips and colored silicone wires to restore the complex layout of the circuit system.

In the production process, the team follows a step-by-step process of "base construction module assembly detail refinement". Firstly, cut the base sheet according to the design drawings, divide the functional areas through laser positioning, and accurately mark the layout boundaries of the charging pile cluster, photovoltaic area, and building. Subsequently, a charging station module was built to combine aluminum alloy profiles with ABS sheets through riveting and bonding processes. The gun line interface, operation panel, and other details were manually polished to restore the operational logic of the equipment; The photovoltaic panel part is bonded to an acrylic substrate through a layered bonding process, simulating the array arrangement of photovoltaic modules; The building is integrated through 3D printing, and the exterior texture is manually polished to restore the layered structure of the building. After laser cutting, the transparent display panel is embedded into the sand table frame to ensure a tight fit with the substrate.

Post production coloring and effect processing are key to improving the degree of restoration. We use a combination of industrial grade spray painting and manual blending technology. First, we spray a light gray primer on the charging pile body. After it dries completely, we use black paint to outline the operation panel and interface contours. The color is uniform and the adhesion is strong, simulating the delicate texture of metal baking paint; The surface of the photovoltaic panel is covered with a blue gradient film, with a light white transition at the edges to simulate the light and shadow effects under sunlight; The buildings are painted with a gradient of beige and light gray, restoring the minimalist style of urban architecture. The brand logo and functional text adopt UV transfer printing technology, with bright and wear-resistant colors, accurately conveying the visual image of the enterprise.

The debugging of the lighting system injects technological vitality into the model. Embedding cool blue LED light strips along the boundaries of functional areas to divide the scene space; The charging station and photovoltaic area are embedded with warm white micro light beads to simulate the operation status of the equipment; The display screen area is equipped with dynamic backlighting to present a virtual interactive interface. The final product not only fully presents the operational logic of integrated light storage and charging, but also conveys the technological image of smart energy through fine processing of materials and processes, which has been highly recognized by customers.
