Castings
Allship Engineering supplies precision marine castings through its partnership with Zollern, one of Europe’s most advanced foundries. Cast components are essential for vessels operating with high-pressure and high-temperature systems in harsh seawater environments. These components offer corrosion resistance, precision, and durability for safety-critical marine applications.
Zollern offers access to over 500 alloy options and multiple casting processes. This enables Allship Engineering to supply marine castings from single replacement parts to large series production for defence and commercial vessels.
What Marine Castings Can Allship Provide?
Castings are metal components formed by pouring molten alloy into a mould to create precise, complex shapes. The process allows design flexibility, high structural integrity, and corrosion resistance for maritime applications.
Allship Engineering provides custom castings for specific marine applications, replacement cast components for repairs and upgrades, and large series production for fleet or OEM requirements.
Common cast components for marine vessels include propellers and propeller assemblies, valve housings, pump bodies and impellers, engine and gearbox housings, high-pressure fittings, seawater treatment components, and structural castings for marine systems. These components range from small precision fittings to large structural assemblies.
Benefits of Marine Castings
Purpose-Built for Harsh Marine Environments
Cast alloys resist seawater corrosion and provide long-term durability in high-pressure, high-stress conditions. These components suit propulsion systems, valves, pumps, and underwater components.
Precision and Design Flexibility
Investment casting produces complex geometries with near-net-shape accuracy. This reduces machining time and provides consistent repeatability for critical components.
High-Performance Alloy Options
Available alloys include copper-aluminium, copper-nickel, bronze, stainless steels, high-temperature steels, nickel-based superalloys, and special alloys for defence and deep-sea applications.
Quality Assurance and Testing
Allship provides tensile testing, hardness testing, impact testing, and metallographic inspection for microstructure quality. Zollern supports ISO, EN, and NADCAP certifications.
Casting Processes
Vacuum Investment Casting
Vacuum investment casting produces high-purity components for complex and safety-critical marine applications. The process minimises defects and impurities.
Open Air Investment Casting
Open air investment casting provides a cost-effective approach for larger production runs without vacuum requirements.
Sand Casting
Sand casting produces large, heavy, and complex marine components including housings, brackets, and structural components.
Croning / Shell Casting
Croning casting delivers high dimensional accuracy for thin-walled or detailed components.
Ceramic Casting
Ceramic casting suits high-temperature or specialised marine applications.
Continuous Casting
Continuous casting produces bars, billets, and linear components for marine manufacturing.
Centrifugal Casting
Centrifugal casting creates seamless, high-strength cylinders, rings, and bushings for rotating marine machinery.
