Other presentation

[Company strength]
Our company pursues the ultimate in precision at the micron level, and we accept small-lot production starting from a single article. No dies are required in our operation, so we can quickly respond to design changes and manage high-mix low volume production. We have dealt with an extensive range of materials, which gives us confidence about our know-how regarding materials. We have significantly reduced manufacturing times through various efforts including a system we developed in-house for managing schedules, manufacturing processes, and quality control and deliveries for ongoing projects. Each worker is also capable of using various kinds of multi-purpose machines such as NC combined lathes, and we can operate some fully automatic NC combined lathes at night.

[Business description]
Our company uses NC combined lathes and other tools to manufacture ultra-high-precision parts such as screws, nuts, and shafts. We can customize products for customers in a wide range of industries including in-vehicle devices, medical devices, and aerospace articles. This is done by serving customers consistently and systematically from the inquiry phase to after-sales service. 

Metal product manufacturing

[Strength of products/technologies]
Our company provides machining with automatic combined NC lathes for bar-shaped non-ferrous metal materials (brass, yellow brass, aluminum, nonferrous alloys), steel (stainless steel, rare metals, titanium), and resins (Teflon, Duracon). Our automatic tools enhance product precision, including concentricity. Our movable spindle lathes are particularly suited to machining micro components and long parts. We also possess other kinds of movable spindle lathes with five-axis control, which makes it possible for us to deal with irregularly shaped workpieces. 

[Representative's message]
In 2012 we participated in the world’s largest medical device fair for the first time (Medica 2012), which is held in Dusseldorf, Germany. We also participated in the Vietnam Business Conference in Kanazawa, which was organized by the Organization for Small and Medium Enterprises and Regional Innovation, Japan (SMRJ). We hope to steadily and gradually move toward overseas expansion. 

[Company structure for market development/overseas expansion]
Our corporate website is already displayed in four languages (English, German, Chinese, and Korean) to attract orders from overseas. The president replies to the dozens of inquires that come through a site (Alibaba) with which we have registered.
