Sakamura

What Sakamura does

Sakamura Machine Co., Ltd. (株式会社阪村機械製作所) is a privately held Japanese manufacturer of horizontal multi-stage forging machines, marketed as "Formers." Founded in 1959 in Kumiyama Town, Kyoto Prefecture (with roots tracing to 1947), the company operates with 121 employees and ¥300M in registered capital, supported by 10 wholly-owned group companies that span manufacturing, die design, parts production, and international service. Its installed base exceeds 5,000 machines across 44 countries, and its forging machines hold industry-leading capacity benchmarks — 21,000kN for hot formers and 13,000kN for cold formers.

The company's product portfolio is organized into three lines: Cold Formers (BPF, PF, BP, NF-NP, MPF-MNF, FR series), Hot Formers (HNP, HBP, HPF, HF, HFW series), and Rotary Rolling Machines (SSR series). Core technology is a crank press-type horizontal multi-stage forging architecture that integrates bar cutting, multi-station forming, and part transfer within a single machine to deliver near-net-shape parts at high speed (40–400 min⁻¹ depending on model). Proprietary features include the Servo Former® servo-motor-driven former, the ATBC automated tool changer (~5-minute changeover), the Three-Part Frame design, the Zero Support System, and the PCS punch cooling system backed by multiple Japanese utility model registrations.

Sakamura earns revenue primarily through one-time capital-equipment sales of its formers (pricing is quote-based, varying by station count, forging force, and customization), complemented by ongoing parts, die, and aftermarket service revenue through its group companies. The go-to-market is enterprise field sales — direct through regional group companies in Japan (Kanto, Tokai, Kansai) plus a US subsidiary in Marion, Ohio and a European service partner — supported by participation in trade shows (wire, MF-TOKYO, IFS China, International Fastener Expo) and a technical content library on the corporate website. Customer segments are diversified across fastener manufacturers, automotive parts suppliers, bearing producers, and construction hardware manufacturers, with named end-applications including connecting rod bolts, CV ball joints, hub materials, and bearing races.

Core offering

Sakamura manufactures horizontal multi-stage forging machines ("Formers") for the cold and hot forming of metal parts, plus rotary thread rolling machines. The machines integrate material cutting, multi-station forming, and part transfer within a single unit to produce near-net-shape fasteners, automotive components, and bearing parts at high speed. The company also sells parts, forging dies, and provides after-sales service through its group of subsidiary companies.

Product overview

Sakamura Machine Co., Ltd. is a manufacturer of horizontal multi-stage forging machines called 'Formers'. The product portfolio consists of three main categories: Cold Formers (cold forging machines that form materials at room temperature), Hot Formers (hot forging machines that form materials heated to 1,000-1,250°C), and Rotary Rolling Machines. Cold Former product lines include the BPF Series (5-7 station bolt/part forming), PF Series (3-7 station general purpose), BP Series (3-4 station bolt press), NF-NP Series (5-7 station nut forming), MPF-MNF Series (3-7 station micro parts), and FR Series (2-5 station combined forging/rolling). Hot Former lines include the HNP Series (3-station nut press), HBP Series (4-station bearing press), HPF Series (4-station part former), HF Series (3-4 station high-force), and HFW Series (4-station twin ram). The SSR Series provides high-precision rotary thread rolling. Sakamura's formers integrate material cutting, multi-station forming, and part transfer within a single machine, enabling near-net-shape production at high speeds for automotive, construction, and industrial applications.
