We manufacture and sell the ANAlyzer laser flaw detector, which detects minute defects and restrains excessively sensitive judgments.
Main Image
We manufacture automobile parts and industrial mechanical parts, and manufacture and sell laser flaw detectors and security gating equipment.
Our laser flaw detector can detect more minute defects compared with the camera method, and it can restrain excessively sensitive judgments. This is based on the need for inspecting the inner and outer walls of cylindrical objects. Our products can also inspect the inner walls of holes with smaller diameters and deeper depths.

    ANAlyzer laser flaw detector

    [Product description] Our product enables non-destructive, non-contact inspection of the inner and outer walls of cylindrical objects using a laser. We can inspect hole interiors where visual inspection is not possible. This is done by using a 200 mm-long (maximum) probe. We can automate OK/NG judgment by setting a threshold level. In-line support is also possible in combination with equipment. Inspection data are fully stored, so feedback to the production line is also possible. The focus depth is deep, so we can continuously inspect workpieces with different diameters. [Market share/Ranking] Laser flaw detector (inner wall): 100%. Laser flaw detector (outer wall): 30%. (We are the only manufacturer of a laser flaw detector for inner walls.)

自由記載

[Company strength]
We conduct mass production of products for automobiles, industrial mechanical parts, and precision products for construction. We are also aware of the importance of quality improvement and cost reduction for enhancing our competitiveness. We focused on the manufacturing-floor situation in the development of our laser flaw detector. Visual inspections are conducted by many inspection staff members, because serious problems with products may be caused by defects on inner or outer walls. These defects include blow holes, scars, and burrs, which are generated in the processing of mechanical parts. We can provide inspection equipment and peripheral equipment that can solve such on-site issues. Improvement in quality control and reduction in inspection costs can be attained simultaneously according to the on-site situation.

[Business description]
We manufacture and sell laser flaw detectors and security gating equipment. We also mainly manufacture automobile parts and industrial mechanical parts.
We predict that the future of automobile parts manufacturing will become severe in the future. This is why we have made energetic efforts to advance new business development. We have independently developed and commercialized a laser flaw detector based on the need for inspecting the inner and outer walls of cylindrical objects. Our products receive high evaluations from the manufacturing floors of major automobile companies and parts manufacturers. This project has been supported by the New Partnership Support Program and the Expert Support Program of SME Support Japan.


[Industry]
Manufacturing

[Strength of products/technologies]
Our laser flaw detector can detect more minute defects compared with other schemes such as a camera method, and it can restrain excessively sensitive judgments. Our products can also inspect the inner walls of holes with smaller diameters and deeper depths. We receive high evaluations for reliability, convenience, and mass productivity. We are developing new technology to enhance detection accuracy and restrain excessively sensitive judgments. This is based on customer requests for improvement and customization of our laser devices. We can continue to provide even more precise equipment.

[Representative's message]
Our company has developed groundbreaking new products based on the precision part manufacturing technology we have been accumulating for over 77 years. Our product development is also based on support by the national government, the prefecture, research institutions, etc. At present we are focusing on domestic sales, but we also aim to develop our overseas business. We hope to actively maintain business expansion based on our new technology.

[Company structure for market development/overseas expansion]
We have established a task force (laser flaw detector project office) in our company, and assigned the head of the president’s office to take charge of this organization. This task force will support new customers and users. We are also actively advancing joint development with major companies, universities, and official institutions in order to devise equipment that is easily operated on-site.
