High-precision molds comparable to mass production in a short delivery time! 【Prototype progressive molds】
We provide high-precision products comparable to mass production within a short delivery time.
The prototype molds manufactured by Nakato Gawa Co., Ltd. are final prototype molds designed for production quantities ranging from 10,000 to 500,000 units (up to 3 million units if upgraded to mass production molds). We provide high-precision products comparable to mass production in a short delivery time. We handle everything from mold manufacturing to sample (press processing). We respond to requests for "the same product as the final version quickly" (as fast as about 2 weeks). 【Features】 ■ Areas of Expertise - Low-voltage components with a thickness of up to 0.2mm (connector terminals, frames, spring plates, etc.) ■ Processing Precision - Product dimensional accuracy: ±0.01mm - Minimum thickness: 0.03mm - Mold processing accuracy: ±0.001mm and above - Clearance: 0.002mm *For more details, please refer to the PDF document or feel free to contact us.

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.
