It is suitable for product function evaluation and shape evaluation with extremely short delivery times.
The prototype type is suitable for product functionality and shape evaluation with ultra-short delivery times by combining bending, cutting, and punching after blank processing through etching. Our specialty lies in weak electrical components (connector terminals, frames, spring plates, etc.) with a plate thickness of up to 0.2 mm. The processing accuracy aims for a product dimension accuracy of ±0.02 mm, a minimum plate thickness of 0.06 mm, a mold processing accuracy of ±0.005 mm, and a clearance of 0.005 mm. For more details, please contact us or refer to the catalog.

Company information
Nakatogawa Giken Co., Ltd. has been manufacturing progressive press molds in Ishinomaki City, Miyagi Prefecture for 35 years, and is a well-known leading prototype progressive mold manufacturer in the Tohoku region. Our company specializes in precision progressive press molds, offering high-precision molds (sales molds) with machining accuracy of ±0.001 and material thickness starting from 0.03mm. We also accommodate prototype molds with the same precision as mass production molds. We can carry out everything from mold design and manufacturing to inspection and press processing in a consistent manner. Additionally, it is a given that Nakatogawa Giken's processing technology can handle sizes as small as a grain of rice. Our ability to consistently perform such high-precision processing is the key to achieving high-precision mold component machining. Furthermore, we have a track record of producing a total of 3,000 progressive molds, and we have preserved all previous prototypes as skeleton samples. With the accumulated samples, our idea generation capabilities allow us to create various mold shapes that meet our customers' requests. At Nakatogawa Giken, we particularly excel in the design and manufacturing of prototype molds for small to medium production runs, and we also support press processing for prototypes and small to medium production. We are confident that we will not be outdone in this area of press processing.
