At Sudou Machinery Co., Ltd., in addition to machining castings, we also procure materials for castings. Of course, you can also trust us with post-processing (surface treatment and heat treatment). Our company provides a consistent response to "planning," "design," "prototype," and "mass production." The reason we can offer the above services is that we have established a network of cooperative companies consisting of about 20 unique firms specializing in casting, processing, and post-processing. These partner companies have strengths in various industries, including automotive, electrical and electronic, and industrial machinery, as well as in handling lot sizes, materials, and casting methods. It is precisely because we have built such a network that we can respond to requests for material procurement and post-processing beyond just machining. [Features] ■ A network of cooperative companies consisting of 20 firms ■ Strengths in various industries such as automotive, electrical and electronic, and industrial machinery ■ Ability to respond to requests for material procurement and post-processing beyond machining *For more details, please refer to the PDF document or feel free to contact us.

At Sudou Machinery Co., Ltd., we handle machining of castings from small lots of about 50 pieces to large lots of tens of thousands of pieces. In machining castings, there are issues related to operating rates and costs for quantities between 50 and 1,000 pieces, and generally, dedicated lines cannot be established for these quantities. As a result, companies that perform casting machining tend to avoid processing in this range. However, at our casting machining website, we gladly accept machining of castings in the range of 50 to 1,000 pieces, which others tend to shy away from. Our ability to accommodate small lot casting machining is due to the establishment of a line that is adaptable to small lots. 【Features】 ■ Capable of machining castings in the range of 50 to 1,000 pieces ■ Established a line that can adapt to small lots *For more details, please refer to the PDF document or feel free to contact us.
