Factory themed souvenir model production case: full process restoration from design to finished product
1、 Design positioning and prototype analysis
Based on the core production scenario of the customer's factory, restore the collaborative state of the factory building, transportation vehicles, large equipment, and ground environment. The prototype includes a yellow factory building, multiple layers of pipelines, blue transport trucks, large cylindrical equipment, and a rock texture on the ground. The overall color tone is mainly yellow, blue, and red, with metallic luster and lighting effects. In production, it is necessary to focus on restoring the proportion relationship of equipment, the sense of scene hierarchy, and the details of industrial elements to ensure a 90% restoration degree.
2、 Material selection and pretreatment
Main structural materials
Factory building and equipment main body: 1.5mm thick ABS plastic board (yellow, blue) is selected, and parts such as factory building columns and equipment contours are laser cut. After cutting, the edges are polished with 800 grit sandpaper and deburred.
Pipes and supports: PVC pipes with diameters of 5mm and 8mm (yellow) are used. After cutting, they are slightly heated and bent into curved pipes with a hot air gun. The supports are cut from 3mm thick aluminum plates and welded and fixed to the equipment base.
Ground and rocks: Use density board (dark brown), apply coffee colored acrylic paint on the surface, dry it thoroughly, simulate the texture of rocks with coarse sandpaper, and then use white paint to dot quartz particles.
Detail Decoration Materials
Truck model: Select a 1:24 scale plastic truck model (blue), disassemble and polish the wheels and windows, replace the black rubber wheels, and restore the brand logo with stickers on the front of the car.
Text and identification: Use a 0.3mm thick brass plate to laser engrave words such as "XX Factory" and "2023", weld them to the side of the factory column, and gold plate the surface.
3、 Manufacturing process and assembly flow
Main structure construction
Factory frame: ABS plastic boards are spliced to form columns and beams, fixed with wood glue, and reinforced internally with fine wooden strips to ensure a verticality error of ≤ 2 °.

Equipment assembly: the cylindrical equipment is divided into two parts, the upper part and the lower part. The internal part is filled with foam glue to enhance stability, the external part is wrapped with aluminum plate to simulate the metal shell, and bolt holes are reserved on the surface.
Scene level creation
Pipeline layout: PVC pipes are fixed with clamps and brackets, with a main pipe height of 15cm and a branch pipe height of 8cm, forming a height difference; The pipeline interface is sealed with hot melt adhesive, and the outer layer is wrapped with silver tape to simulate a metal interface.
Truck parking: Mark the parking position on the density board ground, use small wooden blocks to raise the wheels, simulate the driving state, and face the entrance of the factory with the front of the car.
Overall fixation and base treatment
All components are fixed to a dark brown wooden base with wood glue and screws. The edges of the base are wrapped in wood veneer and coated with varnish on the surface.
4、 Coloring and texture restoration
Base color spraying
Plant and equipment main body: Apply 2-3 layers of yellow acrylic pigment (with a small amount of titanium dioxide to enhance brightness) thinly, and after each layer is dry, lightly grind with 400 grit sandpaper.
Truck: Blue acrylic paint sprayed, windows covered with transparent acrylic varnish, wheels painted black and then dotted with white paint for wheel hub bolts.
Detail aging and metallic texture
Equipment casing: After the yellow base color is dry, apply two thin layers of gold metallic paint (diluted 50%) to simulate an oxide layer; The bolt holes are marked with silver paint and the edges are dyed with black paint.
Pipeline interface: After covering with silver paint, use a fine bristled pen dipped in black paint to draw wear marks.
Lighting and Atmosphere Creation
A warm yellow LED strip is installed on the inside of the base, connected to an external switch through wires. The light shines from the top of the factory and the bottom of the equipment, illuminating the red background board (matte red cardboard) to create a contrast between light and dark.
