We provide the shortest half-day estimate and can immediately procure a variety of processed parts made of metal and resin, including surface treatment and inspection, in small quantities.

To maintain excellent quality and further enhance productivity, we will resolve the complexities of parts procurement. We will reduce the time and costs associated with procurement, allowing you to focus on improving your core productivity. "For example, if you are facing issues like these..." - You want to maintain stable supply through risk reduction by minimizing rework and additional processing. - It's challenging to communicate with various processing companies for a wide variety of parts. - You are unsure which materials and processing methods are best... - You don't need many parts! One or two are sufficient... - You want to lower costs! Due to rising material prices, etc. - You need parts immediately! You're struggling with delivery times. → Please leave such concerns to us! - Over 30 years of experience! More than 1,110 partner companies! - We handle everything from single-item processing to a wide variety of materials and processing methods! - Our company manages parts procurement → surface treatment (hardening, polishing) → inspection all in one go, so you only have one point of contact. - We conduct inspections as well! A reliable double-check system. - We can work with both 2D and 3D drawings! We can even create drawings from scratch if you don't have any. From metals to plastics, we are your go-to for cutting processing of prototype and development parts.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

● 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 to 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 "240well 2D Code Attached Tube" is a product with a 200μl type and a rack lid lock function. It is compatible with liquid nitrogen vapor. It allows for the storage and management of a large number of samples in a small space, making it easier to understand. Additionally, it does not use sealing materials, which improves sealability and allows for safer use. 【Features】 ■ Developed a 2D code attached tube for ultra-micro volumes (200μl) ■ Compatible with liquid nitrogen vapor ■ Adopts a new type of screw cap that does not use O-rings, packing, or gaskets ■ Improved sealability and safer use due to the absence of sealing materials *For more details, please download the PDF or feel free to contact us.
