Craftsmanship in the Display Model of Shield Machine
In the field of tunnel engineering, shield tunneling machines are undoubtedly the "national treasure". How to accurately and aesthetically condense this massive and complex mechanical equipment onto a desk for use in corporate exhibition halls, product promotion, or academic exchanges? This is precisely the core value of our professional model manufacturer. Recently, we have successfully delivered a high-quality static display model of a shield tunneling machine with a scale of 1:50. Now, we will reveal our production philosophy and process to you.
1、 Precise positioning: designed for "display"
Unlike large dynamic models, the core goal of this project is to fully restore the industrial beauty and precision structure of shield tunneling machines within a limited length of 50 centimeters, making it a display that combines aesthetics and professionalism. Therefore, our design strategy focuses on highly simulating the appearance and delicately depicting the details, rather than complex internal motion mechanisms.
2、 Concentrated essence: details determine success or failure
Overall design and proportion: Based on a precise scale of 1:50, our designer has artistically refined and optimized the contour lines of the real shield machine, ensuring that the model is visually upright and powerful, with a compact structure that maintains its grandeur.
Core cutterhead production: As the "facade" of the model, the cutterhead is the top priority of the entire production process. We use a combination of high-precision laser cutting and CNC engraving to accurately reproduce the shape and layout of each rolling cutter, scraper, and bucket using stainless steel material. And through professional spraying and aging processes, the texture of the metal and the traces of wear and tear during work are simulated, which is highly visually impactful.
Shield structure and details: The shield body is made of high-quality alloy materials, and a smooth and flowing surface is created through seamless splicing technology. We use micro carving technology to present hundreds of fine nodes on the shield body, such as injection ports, detection holes, and installation positions of the propulsion cylinder, one by one, even to the point where the bolt models are clearly distinguishable, allowing experts to see the way.
Pipe segment assembly machine and supporting equipment: Although it is a static model, we still focus on shaping key equipment inside the middle shield and tail shield, such as pipe segment assembly machine (assembly gripper), screw conveyor, etc., as key details. By using color separation spraying and etching processes, the three-dimensional and mechanical effects of these components are highlighted, making their functions clear at a glance.
3、 Painting and Texture: Endowing Models with Soul
We have abandoned the monotonous solid color spraying and adopted advanced metal paint as the base, and then used professional modeling techniques such as "dry sweeping" and "stain washing" to highlight the metal heaviness and structural hierarchy of the equipment. Finally, spray protective paint to ensure that the model maintains its luster and delicate touch for a long time.
4、 Craftsmanship in final assembly: Achieving perfect exhibits
After all components are manufactured, they are manually assembled by experienced technicians. We require every component to have a tight fit to ensure that the overall model is seamlessly integrated. In the end, the model was securely installed on a customized acrylic transparent cover and solid wood base, instantly becoming an industrial artwork worth cherishing.
