大型艦船模型的制作是一項融合工程精度與藝術美學的綜合性創作，其流程可拆解為設計研發、材料制備、分部件加工、總裝集成、表面處理五大核心階段，每個環節均需嚴謹的工藝控制與創意發揮。

　　The production of large ship models is a comprehensive creation that integrates engineering precision and artistic aesthetics. Its process can be broken down into five core stages: design and development, material preparation, sub component processing, final assembly and integration, and surface treatment. Each stage requires rigorous process control and creative expression.

　　設計研發階段

　　Design and development stage

　　模型制作始于對原型艦船的深度解構。制作者需通過多維度資料收集，包括歷史影像、技術圖紙、實船照片等，建立三維坐標系進行尺寸換算。例如，某型訓練艦模型以1:200比例縮制，需將實船260米總長轉化為1.3米的模型長度，所有結構參數按比例同步縮放。設計軟件常采用工業級三維建模工具，通過NURBS曲面構建船體流線型輪廓，同時對上層建筑進行模塊化拆分，生成可供數控機床識別的加工圖紙。

　　Model making begins with a deep deconstruction of the prototype ship. The creator needs to collect multidimensional data, including historical images, technical drawings, actual ship photos, etc., to establish a three-dimensional coordinate system for size conversion. For example, if a certain type of training ship model is scaled down to a scale of 1:200, the total length of the actual ship's 260 meters needs to be converted into a model length of 1.3 meters, and all structural parameters need to be scaled synchronously according to the scale. Design software often uses industrial grade 3D modeling tools to construct streamlined ship contours using NURBS surfaces, while modularizing the superstructure to generate machining drawings that can be recognized by CNC machine tools.

　　材料制備階段

　　Material preparation stage

　　根據不同部位的功能需求，材料選擇呈現差異化特征。船體主體多采用工程塑料ABS板材，其良好的加工性能與抗變形特性適合塑造流線型外觀。某型科考船模型選用3mm厚黑色ABS板，經激光切割機精確裁切后，通過熱彎成型工藝塑造出船首飛剪艏的曲面形態。上層建筑則采用航空鋁合金型材，利用五軸加工中心進行鏤空雕刻，既保證結構強度又實現輕量化。甲板表面處理采用0.5mm黃銅板，經化學蝕刻工藝制作出防滑紋路與系纜孔細節。

　　According to the functional requirements of different parts, material selection presents differentiated features. The main body of the ship is mostly made of engineering plastic ABS sheet, which has good processing performance and anti deformation characteristics suitable for shaping streamlined appearance. A certain type of scientific research vessel model uses 3mm thick black ABS board, which is precisely cut by a laser cutting machine and shaped into the curved shape of the bow flying shear bow through hot bending forming technology. The superstructure is made of aviation aluminum alloy profiles, which are hollowed out and carved using a five axis machining center to ensure structural strength and achieve lightweight. The deck surface is treated with 0.5mm brass plate, and anti slip patterns and details of mooring holes are made through chemical etching process.

　　分部件加工階段

　　Partial processing stage

　　船體制作采用分段建造法，將整體劃分為首部、中部、尾部三大模塊。中部艙段需預先嵌入電機支架與傳動軸管，通過3D打印技術制作精密舵機座，確保動力系統安裝精度。上層建筑分七層甲板獨立加工，每層均預留管線通道與設備安裝位。某型客滾船模型的上層建筑包含車輛甲板、客艙、駕駛室等復雜結構，采用真空吸塑工藝制作弧形艙壁，配合手工打磨實現無縫拼接。細節部件如雷達天線、救生艇、系泊纜樁等，運用微雕技術結合失蠟鑄造工藝，將0.3mm直徑的金屬絲加工成欄桿扶手，展現微觀工程美學。

　　The hull is constructed using a segmented construction method, dividing the entire structure into three major modules: the bow, middle, and stern. The central cabin section needs to be pre embedded with motor brackets and transmission shaft tubes, and precision servo mounts can be made through 3D printing technology to ensure the installation accuracy of the power system. The superstructure is divided into seven decks for independent processing, with reserved pipeline channels and equipment installation positions on each floor. The superstructure of a certain type of passenger roll on/roll off ship model includes complex structures such as the vehicle deck, cabin, and driver's cab. The curved cabin walls are made using vacuum vacuum forming technology, and seamless splicing is achieved through manual polishing. Detail components such as radar antennas, lifeboats, mooring bollards, etc. are processed into railings and handrails using micro carving technology combined with wax casting technology, showcasing micro engineering aesthetics.

　　總裝集成階段

　　Final assembly integration stage

　　組裝過程遵循由下至上的建造邏輯。船體底板預先開設龍骨槽，通過定位銷與膠接工藝實現分段對接，使用激光水準儀控制船體水平度。上層建筑采用階梯式堆疊安裝，每層甲板間嵌入橡膠減震墊，既消除裝配間隙又模擬實船隔振設計。動力系統集成時，將無刷電機與減速齒輪箱嵌入預留艙位，傳動軸通過水密軸承貫穿船體，螺旋槳采用3D打印尼龍材料，經動平衡校正后安裝。某型集裝箱船模型在總裝階段創新應用磁吸式快拆設計，使上層建筑可整體拆卸，便于內部設備檢修。

　　The assembly process follows a bottom-up construction logic. The bottom plate of the ship is pre designed with keel grooves, and segmented docking is achieved through positioning pins and bonding processes. The levelness of the ship is controlled using a laser level. The superstructure adopts a stepped stacking installation, with rubber shock absorbers embedded between each deck to eliminate assembly gaps and simulate actual ship vibration isolation design. When integrating the power system, the brushless motor and reduction gearbox are embedded in the reserved cabin, and the transmission shaft penetrates the hull through a watertight bearing. The propeller is made of 3D printed nylon material and installed after dynamic balance correction. A certain type of container ship model innovatively applies magnetic quick disassembly design during the final assembly stage, making the upper structure detachable as a whole and facilitating internal equipment maintenance.

　　表面處理階段

　　Surface treatment stage

　　涂裝工藝采用多層噴涂技術，先施作環氧底漆封閉基材，再噴涂船用聚氨酯面漆。某型科考船模型通過分色遮蓋工藝，在深灰色主色調上繪制出白色水線與紅色吃水線，使用0.2mm極細勾線筆手工描繪舷號字樣。舊化處理運用天然土顏料進行干掃，在舷窗邊緣、甲板接縫處制造銹蝕痕跡，配合海水痕跡特效漆模擬浪花拍擊效果。最終采用消光保護漆定型，既保留金屬質感又防止指紋沾染。細節完善階段，將激光切割的蝕刻片舷梯、3D打印的集裝箱模型等配件進行組裝，使用UV膠水實現毫米級微小部件的固定。

　　The coating process adopts multi-layer spraying technology, first applying epoxy primer to seal the substrate, and then spraying marine polyurethane topcoat. A certain type of scientific research ship model uses color separation and covering technology to draw white waterline and red waterline on the dark gray main color tone, and manually depicts the hull number with a 0.2mm ultra-fine hook pen. The aging treatment uses natural earth pigments for dry sweeping, creating rust marks at the edges of the portholes and deck joints, and simulating the effect of waves hitting with seawater trace special effect paint. The final design adopts matte protective paint, which retains the metallic texture while preventing fingerprint contamination. In the stage of detail improvement, laser cut etched gangways, 3D printed container models and other accessories are assembled, and UV glue is used to fix millimeter sized small components.
