Water jet cutting <Notable processing technology>

Supports processing of a wide range of materials! In addition to square, circular, and ring shapes, we can also process complex shapes.

"Water jet processing" is a machining technology that utilizes the discharge energy of ultra-high-pressure water to cut various materials into arbitrary shapes. In recent years, as materials become harder and more value-added, it has become one of the machining technologies that attract attention, with increasing utility across industries such as aerospace, semiconductor-related fields, shipbuilding, and railway vehicles. We deliver quickly with a rich inventory, comprehensive processing facilities, and a nationwide delivery network. 【Features】 ■ Available for a variety of materials - Water jet processing does not select materials. ■ Unique processing that meets needs - Processing combining "top and bottom milling + water jet" unique to white copper is possible. ■ Quick response to delivery times - A one-stop service from material procurement to processing and delivery enables short lead times. *For more details, please refer to the PDF document or feel free to contact us.

Advantages of water jet cutting

We also accommodate cutting processing with supplied materials! We achieve cost reduction by shortening processing time.

"Water jet cutting" is a processing method that causes less thermal impact and distortion to the material during processing compared to circular saw cutting or band saw cutting. It uses a high-pressure pump to pressurize water, which is then ejected from a small-diameter nozzle, utilizing the energy of ultra-high-pressure water to cut various materials into desired shapes. Additionally, the cut surfaces have a smooth finish, and depending on the conditions, secondary processing may not be necessary, allowing for further cost reduction. [Advantages] - Capable of cutting various metals - No thermal impact on the material - Smooth cut surfaces - Suitable for large and thick plate processing *For more details, please refer to the PDF document or feel free to contact us.

Contract manufacturing of metal 3D printed products.

We will assist you in developing new products and creating tools using a metal 3D printer.

Additive Manufacturing is a manufacturing method that creates and processes complex shapes by layering metal, and it is actively utilized globally. With the latest and largest metal 3D printers, we can significantly reduce the manufacturing time of prototypes in your development. ■ High degree of design freedom - Shapes that were not achievable with cutting or casting are possible - Free design of internal water pipes, such as molds with three-dimensional water channels - Capable of forming with a variety of metals including maraging steel, stainless steel, aluminum, titanium, and Inconel ■ Efficiency and cost reduction - Achieves a reduction in the number of parts by integrating multiple components into a single structure - Reduces the number of parts that require assembly, alleviating the burden of assembly processes and parts management - Reduces the manufacturing time and initial costs of prototypes in development - Directly forming the final product allows for trial runs - Even as service parts, using a 3D printer eliminates the need to store molds, thus avoiding management costs ■ Weight reduction - Shapes that are difficult to achieve with traditional methods, such as honeycomb and lattice structures, are possible - Complex shapes like hollow structures can be formed as a single piece, enabling optimal design products (topology) as well.
