Haranomachi Tekkou Co., Ltd.

We use NC lathes to manufacture aluminum vacuum chambers and other products.

Machining is our main operation, and we also manufacture other products. These include semiconductor production devices, liquid crystal production device parts (aluminum vacuum chambers; related products), jig and tool die parts, pump parts, and other parts for generators and industrial machinery. We have over 40 employees, and more than 20 are publicly certified technicians. Two of our employees have been approved as Monozukuri Meister master craftsmen by the Ministry of Health, Labor and Welfare. We work together to deal with difficult product specifications that involve iron, castings, aluminum, SUS, copper, and special steel. Our parts were adopted for the Shinkai 6500 deep-sea submersible research vehicle in 1990.


Other presentation

[Company strength]
Our company has acquired customers in fast-developing industries and business categories in every era, and we have sincerely responded to their needs. Our strength lies in the wealth of equipment we possess. This includes large five-face machining centers, horizontal boring machines, medium-sized and small machining centers, turning centers, and NC lathes. Our strength also includes the excellent engineers who operate these machines: we offer the best mix of hard and soft technology. We have over 40 young and veteran workers, and more than 20 of our staff members are publicly certified technicians. These are mostly young workers. We also have two veteran workers who have been certified as Monozukuri Meister master craftsmen by the Ministry of Health, Labor and Welfare. We privately believe that their skills are among our greatest strengths. 

[Business description]
Our company was established in 1972 by the previous president as a sole proprietorship, and the initial main business was machining bicycle parts for major manufacturers in the local area. The scope of our business gradually expanded to include consumer electronics and auto parts production equipment. We also took on motors, generators, tire production parts, vacuum device parts for liquid crystal and semiconductor production machines, and pump casings. We now offer machining for various metal products in a wide range of industries as our main business, in addition to some assembly. 

Metal product manufacturing

[Strength of products/technologies]
We offer no standardized original products. We can deal with difficult requirements written in our customers’ product specifications. We can handle machining for a wide range of metals, including iron, castings, aluminum, SUS, copper, and special steel, in addition to concrete and stone. Our cutting-edge equipment performs best when it is operated by our experienced workers with advanced skills. Machining precision is guaranteed up to 1/100 mm, depending on the shape and size. The size can be anywhere between the size of a thumb to 6 m × 4 m × 2 m. 

[Representative's message]
Our company has always proactively worked with new customers and new products in unfamiliar fields with a spirit of challenge ever since our establishment. A major company let us participate in the production of the Shinkai 6500 when our company was less than 20 years old. We had a minor role, but it became a big stepping stone for us to get into other fields. We hope to contribute to society under the theme of being a company that crafts dreams as well as things. We will strive to become a reliable precision machining manufacturer that is needed by our customers, and that earns trust across industrial and business categories. 

[Company structure for market development/overseas expansion]
We are a small company without a sales force. One dedicated sales representative, the president, and a managing director cover the trading area from the Tohoku to Kanto regions. They are all knowledgeable about technical specifications, so feasibility can be determined on the spot during a meeting. Our technology staff will provide sincere responses about further specifications. We are not considering overseas expansion at the moment.

[Awards and media coverage]
We have received many awards from our main customers (major companies), and from the Saga Vocational Ability Development Association (2008).
