Nakakin

What Nakakin does

Nakakin (株式会社ナカキン) is a privately held Japanese industrial manufacturer founded in September 1950 and headquartered in Hirakata, Osaka Prefecture. The company operates two divisions: the Industrial Machinery Division, which produces rotary piston pumps and peripheral equipment (filling machines, blenders, flow meters, drum suction machines) for liquid transfer applications; and the Light Alloy Division, which produces aluminum cast parts — primarily automotive engine components such as intake manifolds and ladder frames, as well as engine components for marine vessels and trucks. Both divisions operate integrated in-house production from design and casting through machining, assembly, testing, and after-sales service. The company is family-owned by the founding Nakamura family, with ~260 domestic employees and ~430 employees at its Indonesian subsidiary (PT. Nakakin Indonesia, as of April 2020).

Nakakin's core competency is casting technology, supported by substantial manufacturing capacity including 65 machining centers (15 of which are 5-axis), 9 NC lathes, eight large and ten medium tiltable casting machines, 16 shell machines, and dedicated quality assurance infrastructure (X-ray inspection, SEM, CMM, 3D scanner, tensile testing). Product differentiation is anchored in hand-adjusted precision assembly of pumps by skilled technicians, proprietary casting simulation (JSCAST) for early defect detection at design stage, and traceability systems that reduce process defects. The company serves customers across food and beverage, cosmetics, pharmaceuticals, chemicals, automotive, and vessel/shipbuilding industries, with a manufacturing subsidiary in Indonesia (PT. Nakakin Indonesia, established May 1995) and a representative office in Eschborn, Germany.

Nakakin generates revenue through direct B2B hardware sales of rotary pumps and aluminum cast parts, with quote-based pricing that supports custom configurations for niche customer requirements. The company maintains a long-standing Japanese customer base with reportedly high domestic market share in rotary pumps for food and beverage applications, and membership in industry associations such as the Japan Casting Association and the Japan Light Alloy Casting Industry Cooperative. Ownership is concentrated within the founding Nakamura family, with no disclosed external investors, private equity backing, public market presence, or recent leadership changes. Strategic partnerships with Nakamura Seiko (precision machining, since 1986) and Osaka Shell (shell mold machinery, established 2001) reinforce vertical integration around the casting technology core.

Core offering

Nakakin manufactures and sells industrial rotary piston pumps, filling machines, blenders, and custom peripheral equipment for liquid transfer across food, beverage, cosmetics, chemical, and pharmaceutical industries (Industrial Machinery Division). It also designs and produces aluminum cast parts for automotive and marine engines and builds casting dies and molds, running design, casting, machining, assembly, and after-sales service in-house (Light Alloy Division). Revenue is generated primarily through direct sales of these manufactured pumps, systems, cast parts, and molds to enterprise customers.

Product overview

Nakakin is a manufacturing company with two core business divisions operating under an integrated production system. The Industrial Machinery Division (産業精機事业部) produces rotary piston pumps, filling machines, and blenders for liquid transfer applications across food, beverage, pharmaceutical, and chemical industries. The Light Alloys Division (軽合金事業部) manufactures aluminum cast parts for automotive engines and marine vessels, along with casting dies and molds. Both divisions conduct design, prototyping, manufacturing, assembly, and testing in-house, enabling end-to-end production control and consistent quality.
