CMMC Holdings LLC

What CMMC Holdings LLC does

CMMC Holdings LLC, operating as Custom Metalizing & Machining (CMMC), is a privately held industrial machine shop founded in 1970 and headquartered at 310 Neeley Street in Sumter, South Carolina. The company provides precision CNC machining, metal fabrication, welding (including laser welding), and reverse engineering services for industrial components, with capability to machine parts up to 77 inches in diameter to tolerances measured in thousandths of an inch. Its service offering spans custom fabrication, OEM replacement parts, gearbox and rotary valve rebuilding, polymer pump and hydraulic cylinder restoration, rotating equipment repair, and 24/7 emergency response repairs supported by pickup and delivery logistics. CMMC is ISO 9001:2015 certified and Buehler certified for rotary valve repair.

CMMC's revenue model is project-based professional services, with quote-driven pricing determined by complexity, materials, turnaround time, and scope; emergency and expedited work likely commands premium pricing. Go-to-market is direct enterprise field sales, with the company engaging maintenance and engineering teams at industrial facilities across the Southeastern United States and, on a project basis, nationwide. Distribution is exclusively direct, supported by a sales phone line (803-464-7489), a website contact form, and a portfolio of more than 30 case studies spanning nine verticals including pulp and paper, hydropower, packaging, polymers and plastics, OSB, nonwoven textiles, metals manufacturing, construction materials, and heavy equipment OEM. Customer concentration is moderated by vertical diversification, though project-based episodic engagements with enterprise buyers imply quarter-to-quarter variability.

Underlying technology is built around specialized capital equipment: CNC machining centers, laser welding, waterjet cutting, and a mobile Keyence 3D scanning system used for in-place reverse engineering without disassembly. The 55+ year operating history, paired with documented emergency-response turnaround (48-hour CAT component fabrication, 4-day nonwoven production line rebuild, one-week repair of 10,000+ lb hydraulic cylinders), constitutes the core value proposition: a regional precision manufacturing partner capable of eliminating 30–50 week OEM lead times and avoiding catastrophic production downtime at lower cost than original equipment replacement.

Broad incumbents

• Methods Machine Tools: North American distributor and service provider of CNC machine tools, automation, and fabrication equipment. Overlaps with CMMC's customer set (precision machining shops and industrial manufacturers) and provides technical service adjacent to CMMC's offerings.
• Kennametal: Global tooling and metalworking solutions provider serving aerospace, defense, transportation, and general industrial markets. Overlaps with CMMC's metal-cutting / machining focus but operates as a tooling OEM rather than a custom service provider.
• Trumpf Inc. Manufacturer of machine tools, laser systems, and automation equipment. Relevant as another major CNC/laser equipment OEM that also offers services; provides a reference point for the metalworking capital equipment ecosystem CMMC operates within.
• Mazak Corporation: Major manufacturer of CNC machine tools (turning centers, machining centers, multi-axis equipment). Adjacent as the OEM of the type of equipment CMMC operates; provides context on industry economics but is a machinery maker, not a service peer.
• Lincoln Electric: Global leader in welding products and consumables with adjacent industrial service offerings. Comparable as a broader incumbent serving welding/fabrication needs across the same industrial customer set, though primarily a product company rather than a custom shop.

Direct peers

• Roush Industries: Engineering services firm with a precision manufacturing arm that performs CNC machining, fabrication, and rapid-turnaround prototype work for industrial and automotive customers. Directly comparable business model of integrated engineering + machining services.
• MetalTek International: Specialty metal component manufacturer and machining services provider serving industrial markets. Comparable in offering custom-fabricated and reverse-engineered metal parts to industrial customers across multiple sectors, with similar project-based, engineering-led sales motion.
