東栄超硬 List of Products and Services

Our company, Tōei Super Hard Co., Ltd. (Aichi Prefecture), specializes in the processing of cemented carbide and is a manufacturer of single-piece and small-lot parts. Crimped parts often have complex shapes and are frequently produced in multiple sets, which can lead to strict tolerances in the accuracy of multiple pieces. As a result, we are often told that "it can't be made with cemented carbide." However, through innovations such as creating processing jigs, we can accommodate various shapes. <Production Examples> ◎ Target: Jigs/Die ■ Product Size: Most are within approximately 50×50×100 mm. ■ Customer Feedback In a situation where there are not many companies that can accommodate our needs, we are satisfied with the accuracy, delivery time, and price. *For more details, please feel free to contact us.
