(Production Example) Stainless steel cleaning basket designed for durability, suitable for cleaning, transportation, and storage.
A robust design that is resistant to deformation for repeated use in cleaning processes. A stainless steel cleaning basket (mesh basket) that accommodates cleaning, transportation, and storage. For storing tools, parts, and containers used in the cleaning process, it is essential to maintain cleanliness and manage them easily, as well as to ensure durability for repeated use. In particular, in environments where cleaning, transportation, and storage are repeated, a stainless steel cleaning basket (stainless steel mesh basket) that is resistant to deformation and can be used consistently is crucial. This product is a robust stainless steel cleaning basket designed for repeated use. Its notable feature is its emphasis on durability, making it easy to handle during cleaning, as well as suitable for inter-process transportation and temporary storage. Additionally, specifications can be tailored according to the application, including dimensions, round bar diameter, mesh size, handle shape, and the presence of dividers. We can easily accommodate requests such as "not suitable for commercially available products" or "want a slightly sturdier design," and consultations can be made even at the stage without drawings. Examples of production including other sizes can be found in the related catalog.
High strength, high elasticity, and wear resistance make it ideal for jigs, contacts, and inspection parts in semiconductor manufacturing equipment!

Started stocking quick-cutting brass C5441B-H Φ1.0 centerless (high-precision grinding) material for inspection probe pins.
Contact probes (semiconductor contact probes) are essential precision electronic components that guarantee the quality and performance of semiconductor devices during manufacturing and inspection processes. In response to the rapidly increasing demand for contact probes in semiconductor testing and other applications, we have begun to stock centerless materials with enhanced outer diameter precision. - Significant reduction in time until processing begins. - Even for rare materials that require guaranteed delivery times, we can now offer flexible responses with our stock items. The Importance of Procurement Design The manufacturing of probe pins often requires rare materials or materials with long lead times, making it crucial to implement a hybrid procurement design that combines "manufactured products" and "commercial stock items." This strategy will be vital for preventing disruptions in our customers' production lines in the future.
