Aluminum alloy castings for ships | Consistent process from wooden patterns to pressure testing, with abundant shipbuilding experience.
AC2A-F
Are you having trouble with separate points of contact for wooden patterns, casting, processing, and pressure testing? We provide comprehensive support from wooden pattern design to pressure testing, and we have extensive experience in shipbuilding.
In shipbuilding and marine parts, aluminum alloy castings are often used, but have you ever struggled to find a supplier that can handle everything from wooden pattern design to casting, machining, and pressure testing? When different companies are involved at each stage, it complicates responsibility boundaries for shape changes and defects, as well as delivery schedule adjustments. There are also limited casting manufacturers that can handle both aluminum and copper alloy castings. Karmo Casting is a rare manufacturer in Japan that produces both aluminum and copper castings. They provide a consistent process in-house from wooden pattern design to casting, machining, and pressure testing, and have manufactured many aluminum and copper products that leverage the characteristics of shipbuilding and marine parts. This product is a completed case of a shipbuilding aluminum alloy casting made from AC2A material, consistently finished from wooden pattern design to machining and pressure testing. We are offering a technical document summarizing the break-even analysis by method and the approach for small lot production for free. Please download it from the link below.
