Asahi Kagaku Kogyo Co., Ltd. (旭化学工業株式会社) is a Japanese plastics manufacturer founded in September 1966 and headquartered in Anjo, Aichi Prefecture, with operating headcount of 161 employees as of August 2025. The company operates a fully integrated one-stop production system spanning mold design, mold fabrication, injection molding, processing, assembly, and quality inspection, supporting two distinct business lines. The OEM contract-manufacturing line produces plastic components and sub-assemblies for power tool manufacturers (notably Makita Corporation since 1969), automotive interior and functional parts, and industrial equipment including scanners and robots, using press capacity up to 1,300 tons and 3-color molding equipment. The proprietary branded product line consists of self-developed resin anchor plugs (Big Anchor, Gokubi, Noble Anchor, Mighty Anchor, AX Plug, Strong Plug, Plastic Anchor) sold to construction materials distributors and contractors for ALC panels, gypsum board, concrete, and soil applications.

Revenue is generated through negotiated B2B contracts with OEM manufacturers and through direct sales of branded anchors to construction distributors; no public pricing is disclosed. The company serves enterprise OEM customers through long-term direct sales relationships and mid-market construction distributors through its proprietary anchor brands, with go-to-market executed by a centralized sales function conducting VE/VA proposals and co-development work.

Asahi Kagaku Kogyo has been publicly traded since 1993 and currently lists on the Nagoya Stock Exchange Main Market (since January 2025), with prior listings on TSE JASDAQ Standard and Osaka Securities Exchange JASDAQ. It operates wholly-owned subsidiaries in Kunshan, China (Asahi Plastic (Kunshan) Co., Ltd., established December 2001) and Rayong Province, Thailand (ASAHI PLUS CO., LTD., established July 2011), giving it a three-country manufacturing footprint. The company has maintained debt-free operations since founding, holds ISO 14001 certification (since 2004), and is led by President and Representative Director Sugiura Takeshi (杉浦 武).

Core offering

Asahi Kagaku Kogyo manufactures custom plastic injection molded parts and assemblies under a fully integrated in-house production system — from mold design and fabrication through molding, processing, assembly, and quality inspection — serving OEM customers in power tools (e.g., Makita since 1969), automotive components, scanners, and industrial robots. The company also designs, manufactures, and sells its own branded line of resin anchor products (Big Anchor, Gokubi, Noble Anchor, Mighty Anchor, AX Plug, Strong Plug, Plastic Anchor) for ALC panels, gypsum board, concrete, and soil applications in the construction materials market.

Product overview

Asahi Kagaku Kogyo is a plastic manufacturing company offering a unified in-house production system spanning mold design, mold manufacturing, injection molding, processing, assembly, and quality control. Its product portfolio consists of two main categories: (1) proprietary brand construction anchors including ALC anchors (ビッグアンカー, ビッグアンカー 1/2 Mk-II), drywall/plasterboard anchors (極美, 極美 小町, ノーブルアンカー, マイティアンカー), concrete anchors (AX plug, ストロングplug), and soil anchors (プラスチックアンカー), all designed and manufactured in-house; and (2) industrial plastic components for original equipment manufacturing, covering power tools (housing sets, motor housings), automotive interiors and functional parts, and other precision components for scanners and industrial robots. The company operates in a single integrated platform model, where the same in-house manufacturing capabilities serve both branded anchor products and contract OEM plastic parts, unified by the company's 'Perfect Plastic' tagline and consistent quality management process.
