Engineering Vessel Model Manufacturer
1、 Project Overview
This project aims to create a scale model of a multifunctional engineering vessel for a specific port client, built at a 1:100 scale with an approximate total length of 80cm. The model will meticulously focus on the hull structure, deck equipment, and detailed painting. The production cycle is expected to span 30 days, divided into three distinct main phases: design, processing, and painting. We employ a specialized “traditional manual craftsmanship + CNC precision” process to achieve an ambitious target restoration rate of 90%. This approach ensures both authenticity and technical accuracy in producing a high-quality industrial model.
2、 List of Materials and Tools
Main material
- Hull: Constructed from 5mm thick oak board laminated structure (offering lightweight durability and ease of carving).
- Deck equipment: Primarily fabricated using ABS plastic sheets, processed via laser cutting (achieving a precision of 0.1mm).
- Detail components: Incorporate brass etching plates for intricate parts like railings and gangways, along with magnetic movable booms for functional details.
Supplementary materials
- Filling and soil simulation: Utilize water-based atomic ash for joint repairs and creating realistic soil fill textures.
- Adhesives: Employ Cyanoacrylate adhesive (CA adhesive) for quick fixes and structural bonding using epoxy resin.
Tool configuration
- CNC and hand tools: Micro table saw for fine woodworking, comprehensive sandpaper set (ranging from 80- to 2000-mesh grits).
- Finishing tools: Pneumatic pencil sharpener for precision detail work, spray pen set (0.3mm caliber) for controlled paint application, and a UV curing lamp for efficient local paint repair and setting.
3、 Core manufacturing process
-
Hull forming stage
- Board splicing: Oak boards are precisely cut by CNC routing according to the ship’s complex curves. Subsequent manual polishing ensures smooth, seamless joints with no discernible steps.
- Structural reinforcement: Internal strength is enhanced using 1mm carbon fiber rods embedded within the hull structure. External soil filling (simulating ballast) is carefully added to level the surface and integrate seamlessly.
- Surface treatment: Specific areas, particularly the bow arc, undergo localized heating with a hot air gun to soften and shape the wood for a precise fit.
-
Equipment assembly stage
- Deck modularization: Equipment such as winches and cranes are assembled according to functional zones on the deck, with maintenance access points intentionally reserved.
- Dynamic mechanism: The main boom utilizes a stainless steel shaft combined with magnetic limit switches, enabling realistic simulation of retraction and extension movements.
- Pipeline restoration: Hydraulic pipelines are meticulously recreated using 0.5mm copper wire, carefully bent and shaped according to the detailed reference drawings.
-
Painting and aging
- Basic color application: The hull is spray-applied with matte navy blue (using GSI water-based paint). Deck areas are treated with a specialized gray-white color separation technique.
- Rusting effect: Employing the dry sweeping method highlights original weld seams. Stain solutions are strategically applied to simulate aged oil deposition effects.
- Waterline treatment: Gradient spray techniques create realistic wave marks along the hull’s waterline. Authentic sea salt crystals are locally applied for added detail.
4、 Quality Control Standards
- Dimensional accuracy: Strict dimensional tolerances are maintained, with an error margin of ≤ 0.5mm. Key parts undergo random inspections using a vernier caliper to ensure rigorous dimensional accuracy.
- Color consistency: Coating color differences are compared against the reference image. Acceptance is based on the D65 standard light source to guarantee color fidelity.
- Functional reliability: All movable components undergo 50 durability tests to ensure smooth operation and freedom from looseness or jamming, upholding the highest standards in model making services.
