Ohno Seiko Co., Ltd.

We manufacture parts and prototypes through a minute-by-minute time management system. 

Our company manufactures and sells parts and prototypes as well as jigs and tools. We mainly supply products to the automobile industry. Our customers include many domestic Japanese companies such as Denso, Toyota Central Research and Development Laboratory, Toyota Group parts manufacturers, and medical device manufacturers. In overseas transactions our products have been exported to the local subsidiaries of Japanese companies. We possess a wealth of equipment (including milling machines, machining centers, and NC lathes). Our internal framework covers a wide range of manufacturing processes including machining, grinding, thermal treatment, and surface treatment. Our company has satisfied various kinds of customer needs and we have expanded our business. This has been done through our minute-by-minute time management (centralized production control system), comprehensive production system (from initial order to delivery), and 24-hour production system (three-crew two-shift system).

[Company strength]
Our company established an integrated production system by introducing various machines and equipment. This includes milling machines, machining centers, NC lathes, wire cut EDM machines, surface grinders, cylindrical grinders, and profile grinders. We combined this with thorough time management (minute-by-minute comprehensive production control system), an integrated production system (from order to delivery), and a 24-hour production system (three-crew two-shift system). This has allowed us to realize express delivery in urgent cases, while ensuring high quality by making use of advanced inspection equipment. This includes the latest three-dimensional measurement instruments in thermostatic chambers at 20 °C ± 1 °C. We have also set up an overseas site in Vietnam to construct a global network for optimal production and specialization as well as cost reduction. 

[Business description]
Our company manufactures prototype precision parts and dedicated machine parts, jigs, and tools, mainly for auto parts manufacturers. Our integrated operation covers thermal treatment and surface treatment in addition to machining and grinding. 

Dedicated machine part, jig, tool, and prototype manufacturing

[Strength of products/technologies]
Our precision part machining technology deals with a wide variety of materials, including difficult-to-machine materials. Our lapping processing creates a superb mirror-like finish of Rz 0.3 microns on flat surfaces and over Rz 0.2 microns on irregular sections. Our machining accuracy with irregular shapes is one of the highest levels achieved in the domestic Japanese market. We also contribute to our customers’ cost reduction efforts by making use of special laser welding machines that cause fewer sink marks. We specialize in recovering and repairing wear and tear, breakage, and dents on dies and machine parts.

[Representative's message]
As part of our mid-term plan we decided to set up two sales sites in Japan and two sales sites overseas. We intend to introduce more detailed and timely sales activities to the domestic Japanese market, and a more solution-oriented attitude for the local subsidiaries of Japanese companies. We will continue to enhance our strengths in technology and sales to serve more customers in the future. 

[Company structure for market development/overseas expansion]
Some staff members in the sales department are in charge of potential customers, and they work as the point of contact for major companies. Technical inquiries are reviewed by sales representatives as well as staff members from the manufacturing department and four technology advisors (ex-employees of major companies). They will visit the customer’s site if this is necessary to solve a problem. Our Vietnam plant also responds to needs from Southeast Asia.

[Market share/Ranking]
Our irregular-shape lapping has earned a high reputation among our customers for its mirror-like finish of over Rz 0.2 µ.
