We would like to introduce a case study on solving issues related to "nozzles for suctioning electronic components." This product is a nozzle used to suction electronic components and move them to the desired location during assembly. However, there was a challenge with the nozzle wearing out quickly, resulting in a short lifespan. To address this, we conducted hearings and proposed changes in material, hardening, and surface treatment. As a result, the hardness of the product increased, the lifespan was extended, and cost reductions became possible, which was greatly appreciated. Our company is open to consultations regarding cost reductions. Please feel free to reach out for inquiries about processing and surface treatment. 【Case Overview】 ■ Product: Nozzle for suctioning electronic components ■ Challenge: Rapid wear of the nozzle used for suctioning products, resulting in a short lifespan ■ Implementation Effect: Increased hardness of the product and extended lifespan *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study on solving issues related to "jigs for transporting electronic components." This product is a jig used in the manufacturing process of electronic components, specifically for transporting parts to the next stage during production. However, the magazine (made of SUS material) that is set in the device was heavy, causing part-time workers to develop tendonitis. As a result of conducting interviews and suggesting a material change, the specific gravity was reduced by half, alleviating the tendonitis and improving work efficiency. We also accept inquiries regarding concerns such as poor work efficiency with no apparent points for improvement. Please feel free to contact us when needed. 【Case Overview】 ■ Product: Jig for transporting electronic components ■ Issue: The magazine (made of SUS material) set in the device was heavy, causing part-time workers to develop tendonitis. ■ Implementation Effect: Specific gravity was reduced by half, alleviating tendonitis and improving work efficiency. *For more details, please refer to the PDF document or feel free to contact us.

Our unique patented technology is utilized for the precision processing and surface treatment of various materials. By applying TiAlN treatment to trays made of stainless steel, titanium, and duralumin, we achieve low reflectivity, which leads to improved image processing and work productivity. Additionally, by applying CrN treatment to the trays, they become more resistant to corrosion, resulting in a longer lifespan. Taper processing makes it easier to insert and remove products. 【Features】 ■ Processing accuracy: High precision achievable ■ Heat resistance: Minimal warping ■ Corrosion resistance: Resistant to corrosion ■ Atmosphere: No gas generation ■ Workability: Easy insertion and removal of products *For more details, please refer to the PDF document or feel free to contact us.
