Company information
Our company is a long-established large machine tool manufacturer with a history of 120 years. Based on the founder's philosophy of "from materials to products," we also manufacture columns, which are components of machine tools, using centrifugal casting methods. Pipes produced by centrifugal casting are characterized by their density and strength, and they are used in various industries, including our own machine tools, the materials industry, the industrial machinery industry, the plant industry, and the construction and civil engineering industry. Currently, for those using seamless steel pipes, spiral-welded steel pipes, or sand-cast pipes, do you have any of the following concerns? - I want to obtain steel pipes with outer diameters, wall thicknesses, and lengths that are not standard. - I want to stabilize material quality. - I want to perform machining on parts that are difficult to process. - I want to procure one piece or small lots. - I want to shorten material delivery times. SNK's centrifugal cast pipes can address these concerns! With the welding technology cultivated through the production of machine tool components and by equipping our own machine tools, we can also accommodate complex shapes and high-precision machining. We have a system in place that allows for integrated production from casting to heat treatment, welding, and machining, even starting from a single product. Please feel free to consult with us.
