Manufacturing Processes for Marine
CNC Machining
Computer Numerical Control machining uses programmed commands to control cutting tools that shape metal and plastic parts with extreme precision. It is one of the most versatile and widely used manufacturing processes in the world.
Sheet Metal Fabrication
Sheet metal fabrication combines cutting, bending, and assembly operations to transform flat sheets into enclosures, brackets, panels, and structural components.
Sand Casting
Sand casting pours molten metal into expendable sand molds to produce parts ranging from small components to multi-ton castings for virtually any metal alloy.
Welding & Assembly
Welding and assembly services join metal components through fusion welding, resistance welding, and mechanical assembly to create complete structures and products.
TIG Welding
TIG welding (GTAW) uses a non-consumable tungsten electrode and inert gas shielding to produce high-quality, precise welds on thin materials and critical applications.
MIG Welding
MIG welding (GMAW) feeds a consumable wire electrode through a welding gun to produce fast, efficient welds on steel, aluminum, and other metals for production applications.
Surface Finishing
Surface finishing processes improve the appearance, corrosion resistance, wear resistance, and functionality of manufactured parts through coatings, treatments, and polishing.
Plating
Plating deposits a thin layer of metal (zinc, nickel, chrome, gold, silver) onto parts for corrosion protection, wear resistance, conductivity, and aesthetics.
Forging
Forging shapes heated metal using compressive force from hammers or presses, producing parts with superior strength, grain structure, and fatigue resistance.
Tube Bending
Tube bending uses mandrels, dies, and CNC-controlled machines to form metal tubing into precise shapes for frames, exhaust systems, roll cages, and fluid transport.
Marine Manufacturing FAQ
What materials resist saltwater corrosion?
Cupro-nickel alloys (70/30, 90/10) are excellent for seawater piping. Marine-grade aluminum (5083, 5086) resists saltwater corrosion. Duplex stainless steel handles aggressive marine environments. Proper cathodic protection extends steel structure life.
What classification societies approve marine manufacturing?
Major classification societies include ABS (American Bureau of Shipping), Lloyd's Register, DNV (Det Norske Veritas), and Bureau Veritas. They certify that vessels and offshore structures meet safety standards for materials, fabrication, and design.
What welding processes are used in shipbuilding?
MIG welding (FCAW) dominates shipbuilding for structural steel due to high deposition rates. TIG welding is used for piping and critical joints. Submerged arc welding (SAW) is used for long, straight panel seams. Robotic welding is increasing in modern shipyards.
