Neftec

What Neftec does

Neftec Corporation is a Kawaguchi City, Japan-based manufacturer specializing exclusively in short-fibre Carbon/Carbon (C/C) composite materials and precision-machined components derived from them. The firm, founded in 1980 and led by President and Chief Engineer Takao Nakagawa, has accumulated 40+ years of dedicated expertise in random-weave, short-fibre C/C composites - a discipline distinct from long-fibre C/C and graphite-based alternatives. Its product portfolio is anchored by the proprietary PC series raw plates and sheets (PC70, PC70H, PC30, PC70i), where PC70 covers approximately 90% of heat-treatment applications up to 2000°C and PC30 extends operating range to 2400°C. These base materials are precision-machined into finished industrial components - heater elements, threaded rods and nuts, fixtures and baskets (including the modular NefGrid system), springs and sprung washers, and application-specific parts for semiconductor crystal growth, photovoltaic polysilicon processing, aerospace electric propulsion, and metallurgical heat-treatment furnaces.

The firm's underlying technology is its proprietary PM Method manufacturing process, which the company states produces exceptionally high-strength composites with shorter production times, lower waste, and reduced energy consumption compared to conventional C/C manufacturing. Neftec claims its composites have the highest Inter-laminar Strength (ILSS) on the market - rivalling some 3D composites - reducing de-lamination failure risk, the leading cause of C/C failure. Its 2.5D short/chopped-fibre composite structure is designed to combine 3D-like mechanical performance with 2D-like cost economics, supporting a value proposition centered on energy efficiency, lightweight properties (claimed at 1/5 the weight of iron), and dimensional stability at extreme temperatures.

Neftec operates a B2B enterprise field-sales motion complemented by a formal reseller program. Revenue is generated through direct hardware sales of C/C plates/sheets, machined components, and bespoke engineered parts on a quote-based pricing model - pricing is not publicly disclosed. The primary customer segments are aerospace (satellite electric propulsion, rocket nozzle heat-shields), semiconductor (silicon crystal growth at temperatures above 1,400°C, wafer handling), heat-treatment (furnace fixtures, quenching, brazing, sintering), and photovoltaic (polysilicon crystallization). Secondary exposure spans automotive and EV battery cell manufacturing via PECVD and HJT process support. The company claims global reach with regional sales contacts for Japan and Asia-Pacific, and in May 2025 announced a strategic partnership to expand its product line into adjacent graphite and insulation solutions.

Core offering

Neftec manufactures short-fibre Carbon/Carbon (C/C) composite materials under its proprietary PM Method and sells them as raw plates/sheets (PC Series grades PC70, PC70H, PC30, PC70i) and as precision-machined finished components including heater elements, threaded rods and nuts, fixtures, baskets, trays, springs and sprung washers. Products are supplied to industrial customers in aerospace, semiconductor manufacturing, metallurgical heat-treatment, photovoltaic/solar, automotive and electric vehicle industries for use in extreme-temperature environments up to 2400°C.

Product overview

Neftec is a Japanese manufacturer specializing exclusively in short-fibre Carbon/Carbon (C/C) composite materials. The company offers a portfolio of PC Series composites (PC70, PC70H, PC30, PC70i) as raw material plates, sheets, and blocks, which are precision machined into finished components including heater elements, springs, fixtures, threaded rods, nuts, and custom-designed parts. The PC70 composite serves as the primary product covering most heat-treatment applications, while PC30 handles higher-temperature environments up to 2400°C. Additional services include in-house application design for bespoke fixtures. The product line was expanded in 2025 through a partnership to include graphite felts, insulation, and custom graphite profiles.
