The Thai factory promotes optimal manufacturing in cooperation with the headquarters factory in Japan. In February 2012, the company built Kobayashi Kako in the Eastern Seaboard Industrial Estate in Rayong Province, Thailand. In February 2012, the company built Kobayashi Kako in the Eastern Seaboard Industrial Estate in Rayong Province, Thailand, just as one of the company's major customers, an industrial equipment manufacturer, was building a new plant in Thailand. When the customer entered Thailand, no other company in our industry stepped up, so we saw it as an opportunity to expand overseas. In fact, in Thailand, we can have many opportunities to meet with major manufacturers that we cannot even have a chance to weld in Japan, as well as major Japanese manufacturers of agricultural machinery, automobiles, and elevators and escalators that are operating in Thailand. First of all, you will develop new customers at the Thai factory and meet their Q, C, and D requirements. Eventually, we would like to receive orders at our main plant in Japan. The Thai plant has only been up and running for a short time, but we are aiming to make it independent and profitable as soon as possible. The manufacturing process at the Thai plant starts with local estimates, followed by drawing orders, development, and processing. Currently, 100% of our sales are related to forklifts, and we manufacture forklift side covers, backrests, and welding jigs. We handle plate thicknesses from 1.6 to 40mm, and process up to 19mm using the FO-MII, while cutting above 19mm is done by a subcontract factory in the suburbs. In addition, the head office plant in Japan and the plant in Thailand flexibly exchange parts according to the degree of processing difficulty. For example, products with complex shapes are supplied from the head office plant in Japan to the head office plant in Japan after the Thai plant has completed the blank to welding process. The number of employees at the Thai factory is 40, and there are no Japanese staff stationed there. The production schedule and arrangements are managed by a locally hired Thai factory manager.
