CK composites

What CK composites does

CK Composites (legally C-K Composites Co, LLC) is a privately held custom engineered composite solutions manufacturer founded in 1985 and headquartered in Mount Pleasant, Pennsylvania, with operational lineage extending to the 1950s when European firm Permali Composites established North American wood-composite manufacturing. The company operates a single production facility of more than 80,000 square feet in the foothills of the Laurel Mountains, roughly 50 miles southeast of Pittsburgh, and serves electrical utilities, defense contractors, medical equipment manufacturers, oil and gas operators, rail transportation systems, and wastewater treatment operators with quote-priced, application-specific composite components.

The product portfolio is organized around three proprietary brands covering distinct composite technologies. InsuLam is a densified wood laminate offered in two grades (Insulam LH non-impregnated and Insulam EH fully impregnated), manufactured to DIN 7707 and IEC 61061 standards and used for structural components in oil-insulated power transformers and cryogenic LNG applications. InsulVolt comprises proprietary Bis-a and cycloaliphatic epoxy formulations processed via vacuum casting and automatic pressure gelation (APG/LIM) to produce bushings, tap-changer castings, and weather cases rated from 5 kV to 69 kV, with individual part weights exceeding 100 pounds. InsulWynd is a filament-wound fiberglass product line made on nine winding machines—two computer-controlled with quick changeover—producing tubes up to 40 feet in length and 6 feet in diameter for MRI tunnels, pressure vessels, interrupter tubes, and submarine radome housings. In-house capabilities include engineering design, finite element analysis, precision CNC machining, manual milling and turning, and a quality test stack featuring a 200 KV/60 Hz test set, a 400 KV impulse generator, and a 60,000 lb universal testing machine. The quality system is certified to ISO-9001, MIL-I-45208A, and ANSI/NCSL Z540-1, with active pursuit of NIST 800-171 / CMMC compliance for defense contracting.

Revenue is generated on a project basis through direct enterprise field sales, with no resellers, distributors, or standardized list pricing and order sizes ranging from single parts and assemblies to high-volume production runs. The company markets through a corporate website (ckcomposites.com) with product and industry pages and a LinkedIn corporate presence, and is currently recruiting across engineering and manufacturing functions. The company shows no disclosed parent, subsidiaries, funding events, M&A history, partnerships, or leadership changes in the input sources.
