What National Molding does
National Molding, LLC is a privately held precision injection molding contract manufacturer founded in 1965 and headquartered in Miami Lakes, Florida. The company produces over 3.5 billion precision plastic components annually across four manufacturing facilities located in Miami Lakes FL (110,000 sq ft, 95 machines), Largo FL (107,000 sq ft including a Class 8 cleanroom, 61 machines), Toronto ON (91,000 sq ft, 60 machines), and Shanghai, China (65,000 sq ft, 43 machines), totaling 259+ injection molding machines ranging from 17 to 550 tons. It serves automotive Tier 1/2 suppliers and direct OEMs, medical device manufacturers producing Class I and Class II devices, US military and law enforcement, and commercial/industrial customers through sub-brands DuraflexUSA (Berry-compliant plastic buckles and fasteners) and a tactical body armor release systems line (MSV Gen IV for US Army IOTV Gen III, SPCS, FIOTV vests).
The company's competitive position rests on its proprietary Hetero-Cavity modular molding system, used in over 80% of products, which reduces tooling costs to roughly one-third of conventional custom tools and enables tool changes in minutes. It applies scientific injection molding methodologies including MoldFlow Analysis, RJG Master Molding techniques, and in-mold cavity pressure transducers to support tight-tolerance production (tolerances as tight as 0.05mm) in engineered resins including PEEK, PPA, and PPS. It holds IATF 16949 across three facilities, ISO 13485 and ISO 9001 at the Largo medical site, ISO 14001 at Toronto, FDA registration with cGMP compliance, and Berry Amendment/Buy America Act compliance for DuraflexUSA. It delivers complementary services including Design for Manufacturability (DFM) consulting, in-house tooling design and CNC/EDM machining, secondary operations (adhesive bonding, ultrasonic and spin welding, heat staking, thermoforming), and quality inspection.
National Molding monetizes through two channels: (1) project-based and recurring contract manufacturing revenue from automotive, medical, commercial, and defense customers, with quote-based pricing tied to part complexity, material selection, volumes, and tooling (Net 30 standard terms), and (2) unit-priced DuraflexUSA hardware sales through a North American and international distributor network. The company is led by CEO Mark McCollough and CFO Scott Mueller, with executive depth across automotive operations (Ralf Zimmer), medical manufacturing (Mike Fischer), and engineering (Annette Langhammer, Director of Advanced Engineering). It was built in part through acquisitions including Security Plastics (2002), Ven-Tel Plastics (2015, medical), and Dynaplas Ltd. (2017, Toronto).
