Core value of stamping technology in the shipbuilding industry lies in: lightweighting, standardization, high efficiency, and cost reduction for secondary components.

Here are the specific functions and application scenarios of metal stamping parts in the shipbuilding industry:
1. Marine Outfitting 
Outfitting refers to all the equipment and devices installed after the ship's structure is completed. This is the most widely used field for stamping parts.
Doors， windows， and covers：
Function： Provide sealing， ventilation， or maintenance passages.
Specific products： Ship-specific louvers (formed by stamping for ventilation in the engine room)， sealing devices for manhole covers， locks and hinges for watertight doors.
Pipe fixation parts：
Function： The ship has several kilometers of pipes (water， oil， gas) that need to be fixed to prevent loosening due to sea wave fluctuations.
Specific products： U-shaped pipe clamps， flange covers， supports. These are usually formed by galvanized steel or stainless steel stamping.

2. Electrical & Cable Management
Modern ships are "floating power stations"， with a huge amount of cable laying.
Cable trays ：
Function： Support and protect cables.
Specific products： Ship-specific cable trays are usually perforated metal plates， and the holes (for heat dissipation and weight reduction) and reinforcing ribs are processed by large stamping dies or CNC stamping machines.
Terminal boxes and switch cabinets：
Function： Protect electrical connection points and prevent salt fog corrosion.
Specific products： Various terminal connectors， instrument panel shells， switch panels.

3. Interior Accommodation
For passenger ships， cruise ships， and commercial ships， stamping parts are used to construct a comfortable living environment.
Ceiling and wall panel systems：
Function： Decoration， fire protection， sound insulation.
Specific products： Aluminum alloy panels， micro-perforated sound-absorbing panels. These panels are formed by stamping with a clamping structure and decorative patterns.
Furniture hardware：
Function： Fix ship furniture (beds， cabinets)， preventing movement during storms.
Specific products： Anti-wave hooks， drawer slides， cabinet door hinges.

4. Sealing & Vibration Damping
Ship engines and propellers generate huge vibrations， and the marine environment is highly corrosive.
Metal gaskets ：
Function： Used for sealing at pipe flange connections and engine cylinder covers.
Specific products： Steel strips for metal wound gaskets， copper gaskets.
Adjusting Shims：
Function： Used for fine adjustment of the height and levelness of the base when installing large equipment (such as main engines， generators).
Specific products： Precision stainless steel stamped plates of different thicknesses.

5. Auxiliary Machinery & HVAC
Fan components： Flange rings of ventilation ducts， regulating valve plates of air outlets.
Filter assemblies： Metal mesh frames inside seawater filters or fuel filters.

6. Why does the shipbuilding industry need stamping parts？ (Core Advantages)
Weight Reduction：
In non-load-bearing structural components (such as cable trays， ventilation outlets)， using thin-walled high-strength stamping parts instead of casting parts or thick plate welding parts can significantly reduce the ship's weight， thereby increasing cargo capacity or saving fuel.
Processing of corrosion-resistant materials：
The ship extensively uses 316L stainless steel， aluminum alloy， and even titanium alloy to resist seawater corrosion. Stamping is the most cost-effective (with less waste) and efficient process for processing these expensive materials.
Standardization and interchangeability:
A ship requires thousands of pipe clamps or cable supports. The stamping production ensures that the size of each part is completely consistent, significantly improving the installation efficiency of the shipyard workers. 

Summary

Although the shipbuilding industry is often perceived as "big steel", metal stamping parts play a crucial role in supporting the operation of ships at the details level. They form the "nervous system protective shell" (cable trays), "breathing system" (ventilation louvers), and "living space" (interior panels) of ships. Without stamping parts, the construction efficiency of modern ships would be significantly reduced, and the weight and cost would be difficult to control.
