In the case of prototypes, I think there are many instances where people give up due to higher costs compared to mass production, but please feel free to contact us. We welcome inquiries and requests for quotes not only for regular line production but also for small lot prototype manufacturing.

A press die is a machine that is equipped with a die made for a press machine (a machine that moves up and down). Material is placed between the two halves of the die, and by operating the press machine to press from above and below, the product is created. Among press dies, there are different manufacturing methods for what are called single-stroke dies and progressive dies.

Our company is a metal parts manufacturer located in Gunma Prefecture. We mainly handle mold design and manufacturing (CAD/CAM), new models, repairs, modifications, and parts processing and finishing (mirror polishing) primarily for the automotive sector, including dashboard components, console boxes, airbag-related parts, and door-related parts. A mold refers to the shape created for the product we want to make, which is then used as a basis for producing the product. In the case of metal products, a high strength is required for the mold's components because large pressure is needed when pouring the product material into the mold or when ejecting the formed product from the mold. Therefore, the components of the mold are primarily made of metal materials, making the mold very robust and heavy. Molds are essential for producing the same shaped items accurately and at a lower cost in mass production.
