SunPlus Co., Ltd.

We have experience in plastic and aluminum machining.

Our company manufactures and sells plastic and aluminum machined parts. Our main products are medical equipment parts, semiconductor-related parts, parts for newspaper advertising leaflet insertion machines and underwater photography equipment, and inspection and assembly jigs. We have many customers among major companies in Japan. We have been increasing our business volume by satisfying a broad range of customer needs for trial manufacturing, small-lot production, and mass production, including injection molding and assembly. We have confidence in the technologies we have accumulated regarding machining resin materials and sealing underwater photography equipment through the development of peripheral parts and plasma sterilizers. Our pressure-resistant waterproof casings and vacuum containers based on these technologies are highly appreciated by our customers.

[Company strength]
We limited our machining to resin and aluminum materials about 30 years ago and started to replace general-purpose machines with NC machines earlier than other companies. We have been proactively implementing technologies and machines that lead the times, such as combined machining, 3D machining, and then multi-axis machining. We constantly work hard on rapid development to satisfy customer requests in terms of quality, delivery, and cost by extending the range of our machining. We take on customer requests and issues concerning resin and aluminum machining and product assembly. We support our customers with trial manufacturing, mass production, and design proposals in development. We have been earning customer trust by building up know-how cultivated through our processing.

[Business description]
We mainly use small machining centers and CNC composite lathes to machine plastic and other resin products and aluminum products.  Our business covers a wide range from injection molding to assembly. Our main products are medical equipment parts, semiconductor-related parts, parts for newspaper advertising leaflet insertion machines and underwater photography equipment, and various inspection and assembly jigs. We possess sufficient technology, experience, and production capacity for any kind of production from trial manufacturing and small-lot production to mass production and assembly.
