American Fine Sinter

What American Fine Sinter does

American Fine Sinter Co., Ltd. (AFS) is a privately held, Ohio-based manufacturer of precision sintered metal components for the global automotive industry, operating a single production facility at 957 N. Maule Rd., Tiffin, Ohio. The company specializes in powder-metallurgy sintering to produce three core product families — internal engine components, transmission components, and vehicle suspension components — that it supplies directly to some of the world's largest automotive OEMs and tier-one parts suppliers. AFS positions its sintering process as differentiated within the automotive sector and has received multiple industry awards for precision, quality, and environmentally responsible manufacturing, supported by a workforce with more than 20 years of tenure in some cases.

The company's business model is a B2B contract-manufacturing model: it sells precision components under long-term supply agreements to OEM procurement and engineering teams, with negotiated (non-public) pricing tied to volume commitments. Go-to-market is sales-led and direct, with no intermediaries; products are delivered straight to customer manufacturing facilities across a domestic North American footprint. The Tiffin site houses 101–250 employees, and AFS has historically been a stable employer in Seneca County.

AFS is a wholly owned subsidiary of Fine Sinter Co. (Japan). Effective April 28, 2026, Fine Sinter announced its intention to gradually exit North American production operations following a review of North American demand and overall Group capacity; future North American production will be sourced from other Group facilities, with a transition period of approximately two years. AFS has stopped hiring for permanent positions, is closing temporary roles first, and is offering retention incentives and severance to remaining staff, materially altering its forward operating profile.
