Hirano Seisakusho Co., Ltd.

Our company is growing in Japan and abroad by machining metal parts.

We are a metal part manufacturer established in 1961. Our company mainly machines engine parts for transportation equipment and construction machinery as well as parts related to semiconductor manufacturing equipment. We have many customers in Japan, including Komatsu, Cummins Komatsu Engine, T.RAD, Mitsubishi Heavy Industries, and MAHLE Filter Systems. We have experience in delivering our products to Japanese companies overseas, and also to the U.S. company GM. We have an integrated system from material procurement to machining, assembly, inspection, and shipping. Our company has also focused on cultivating human resources. We have been increasing our business volume by tackling a single-piece flow production system in which multi-skilled staff quickly satisfy small-lot production needs.

[Business description]
Our company offers metal working manufacturing of engine parts for transportation equipment and construction machinery as well as parts for semiconductor manufacturing equipment. Our main customers are Komatsu, T.RAD, and Ryobi. Large housing parts account for a large percentage of our products (construction machinery: 48%; trucks: 43%). A feature of our company is that we excel at manufacturing large parts, and we are cultivating multi-skilled human resources so that each worker can cope with all processes. We can manufacture products by letting one piece through at a time, and we have advantages in high-mix low-volume production.
