C.H.K. MANUFACTURING, INC.

C.H.K. Manufacturing, Inc. specializes in the precision fabrication and production of polymer and rubber components for government and defense applications, leveraging its expertise in thermoplastic and elastomeric molding technologies. As a Woman-Owned Business certified under the SBA’s Women-Owned Small Business (WOSB) program, the company delivers mission-critical parts requiring tight tolerances, environmental resilience, and compliance with military and federal material standards such as MIL-SPEC and ASTM. Their technical capabilities include injection molding, compression molding, extrusion, and secondary operations like ultrasonic welding and precision die-cutting, serving applications where durability, chemical resistance, and thermal stability are essential. The firm’s focus on quality control systems and certified manufacturing processes ensures consistent performance in demanding operational environments. Award history is not available to confirm specific agency engagements, so no definitive patterns of federal client relationships can be identified. However, given its NAICS classification under 326111 (Plastic Product Manufacturing), the company is positioned within the broader defense, aerospace, and federal infrastructure supply chain, where custom rubber and plastic components are used in sealing systems, gaskets, insulation, and ergonomic hardware. Their market positioning aligns with suppliers of non-metallic parts for equipment maintenance, vehicle subsystems, and field-deployable systems requiring low-signature, high-reliability materials. C.H.K. Manufacturing, Inc. operates as a small business entity based in Oakland, California, with a localized production footprint supporting regional federal and contractor supply needs. The company’s WOSB certification enhances its eligibility for set-aside contracts and underscores its commitment to diversity in federal procurement. While geographic reach is centered in the West Coast, its certification and manufacturing capabilities enable participation in nationwide government supply networks requiring compliant, small-scale production partners.
