Aoi Seira Seisakusho Co., Ltd.

We are manufacturing special ultraprecision screws and fastener parts by cold heading processing.

We have half a century of history as a special ultraprecision screw and fastener part manufacturer. Earlier, we introduced a multi-station parts former that allows cold heading to products of a complicated shape. We also have processing equipment for dies and molds, and examination equipment to guarantee dimensional accuracy in micron units. During this period, we accumulated unique technologies of cold heading and form rolling processing. We have succeeded in low-cost manufacturing of difficult-to-process products, stable manufacturing of high precision products, and other tasks in recent years. The parts including shoulder screws, stepped rivets, small male shoulder screws, shafts, and special screws are used in the fields of automobiles, OA equipment, cellular phones, and others. We are producing the parts in Yamanashi Prefecture, and the two countries of China and Thailand.
