We will be exhibiting at Gunma Tech EXPO 2025.

Shortest half-day estimate / Processed parts are purchased exclusively from our company! We will streamline procurement operations from process management to quality control.

◎Benefits of Using Our Services Our company is your sole procurement contact! Leave everything from processing to surface treatment to us! We also handle everything from process management to quality control in one go. Our strength lies in our "unique procurement system" that enables the streamlining and simplification of procurement operations. We can work with both 2D and 3D drawings! If you don't have a drawing, we can also create one from the actual item. ◎Reasons With about 30 years of experience in procuring processed parts and a network of industrial machinery accumulated since our founding, we are partnered with over 1,100 cooperating companies both domestically and internationally, allowing us to handle all types of processing needs! ◎Unique Strengths (Quality Assurance) We have our own inspection facilities (three locations nationwide). We conduct inspections of all parts using digital measuring equipment such as three-dimensional measuring machines and image dimension measuring devices. We can also issue inspection reports. ◎Features - We can handle small quantities of various types with just one drawing and one part! - Processing technologies include MC cutting, lathes, milling, laser bending, resin cutting, can manufacturing, wire, discharge machining, gears, etc. We can work with materials ranging from metals to resins! Trust us with the cutting and processing of prototype and development parts.

• Automatic sorting machine

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
