株式会社阪井金属製作所 Product Lineup

We would like to introduce our "can manufacturing" process. All of our craftsmen hold JIS Z3801 welding qualifications, and under a strict inspection system, we strive to ensure that the same quality can be provided regardless of which craftsman is producing the work. By having everyone possess the same skills rather than relying on a flow production system by specific individuals, we enable cell production, which allows us to respond to short delivery times and adhere to deadlines. 【Features】 ■ High quality, short delivery production ■ All members hold welding qualifications ■ Domestic manufacturing ■ From welding processing to five-sided machining *For more details, please download the PDF or feel free to contact us.

This document is a guide that summarizes the know-how to achieve approximately 30% cost reduction and a decrease in procurement man-hours through domestic sourcing. It addresses procurement challenges for high-difficulty processed products such as hard-to-machine materials, extremely tight tolerances, and multi-process items that are often rejected in automatic estimates as "not feasible," as well as quality concerns in overseas procurement. By leveraging a global manufacturing network and a double-check system domestically, it enables cost reduction while ensuring quality at a Japanese level.
