Copper alloy castings for ships | Consistent from casting to pressure testing, strong in pressure resistance for thick sections.
There are concerns about the pressure resistance performance of copper alloy castings for ships with thick meat. We provide consistent support from casting to machining and pressure testing, with proven results in both aluminum and copper.
Have you ever struggled to find a supplier that can handle the casting, machining, and pressure testing all at once for parts like copper alloy castings used in ships, where the pressure resistance of thick sections is critical? When casting, machining, and pressure testing are outsourced to different companies, the division of responsibility in the event of defects can become ambiguous. There are also limited foundries that can handle both copper alloys and pressure testing. Karmo Casting is a rare manufacturer in Japan that produces both aluminum and copper castings. We provide a consistent process from casting to machining and pressure testing in-house, with a strong focus on the pressure resistance of thick products. We have a proven track record of manufacturing ship parts for many years and can accommodate a wide range of shapes and materials. This product is a completed case of a ship-use copper alloy casting made from CAC406 material, finished consistently from casting to machining and pressure testing. We are offering a technical document summarizing the break-even points by method and considerations for small lot production for free. Please download it from the link below.
