Work that reflects our customers’ smiles
    Imai Gikou began in 1926 by hand carving molds for imprinting tableware patterns, a local industry in the region. Now, four generations later, we take pride in our status as a company of polishing professionals, able to polish any molds or metal surfaces down to 1/1000-micron accuracy, using know-how that satisfies our customers.
    All of our employees share the aim of work that satisfies customers under the slogan “Delivered on time through assured technology,” and have performed precision polishing under demands for flatness, surface roughness, and accuracy, on three-dimensional forms, small objects, large objects up to 4.8 tons, and even flexible objects such as electrical discharge machining electrodes. Equipped with welding machines as well as our grinding technology, we are able to deal in-house with insufficient overlay, a problem that has led to losses in conventional work schedules. By doing so, we offer our customers efficiency and cost reductions.

    Grinding & laser welding
    Imai Gikou also performs mirror finishing of new molds and maintenance of molds currently in use.
    In the past, in cases of design changes to molds, insufficient overlay, or sink marks and pinholes in molds, a mold had to be pulled up, the welding performed at another factory, and the mold brought in again. However, by placing welding equipment in-house, Imai Gikou can now perform one-stop mirror finishing and maintenance in-house.
    Loving our work, Loving the community, Loving the customer.
