【ごあいさつ】

 

  Thank you for visiting the Chokai Manufacturing Co., Ltd. website.  We are a machine manufacturing company specializing in a variety of metal processing.  

  Founded in 1974, we have been working alongside Japan's rapid growth period in manufacturing. While constantly adapting to the times, we have been supported by many customers for over 40 years, specializing in machining, primarily NC lathe processing, as well as machining, manual lathe processing, and the manufacture of various precision parts. With a focus on manufacturing that looks 10 years into the future, we have expanded our factory and introduced the latest machinery, including Yamazaki Mazak's large multitasking machine (INTEGREX e-650H), a rare model installed in Japan, which enables simultaneous five-axis control machining.

 

  Our main processing duties are a wide variety of metal products, ranging from automotive-related molds to parts for aviation, oil plants, and steel-related companies. Many of these products are simply "components," so looking at them alone can make it difficult to understand what they are. However, we take responsibility and pride in the work we undertake, and strive to meet our customers' needs. Even if you find yourself thinking, "I want this product, but I don't know to whom I should ask for," please contact us and we will address your request sincerely, leveraging our knowledge and experience to do our utmost.

 

  We specialize in fast work, and even for rush orders, we will not compromise on quality. All of our employees work together every day to strive to be a company that meets our customers' expectations. If you need metal processing, please contact Chokai Manufacturing first.
