What 7-SIGMA does

7-SIGMA is a privately held, family-owned precision polymer and metal component manufacturer founded in 1973 by former NASA scientist Jerzy Wyrobek and his two sons, headquartered in the Minneapolis/New Hope, Minnesota area with manufacturing operations in Hong Kong and Shanghai. The company produces high-performance polymer and metal components and assemblies for four primary verticals: medical devices, printing (fuser rollers, pressure rollers, media path rollers for printers/copiers), aerospace, and industrial applications. Its core manufacturing capabilities include two-part liquid injection molding, liquid silicone molding, Teflon and polymer/metal adhesion bonding, CNC machining and grinding, polymer coatings, and assemblies, supported by an in-house polymer characterization laboratory (rheology, cure characteristics, TGA, DSC, FTIR, GC, MS) and ISO 9001/14001-certified quality systems. The company operates a wholly-owned sub-brand, 7S3 (7-SIGMA Simulation Systems), which designs and sells modular high-fidelity medical simulation hardware — notably the 7S3 Modular Airway Training System, the Sensor-Based Novice Airway Trainer, the Sensor-Based Novice Bronchoscopy Trainer, and the 'Mae' modular pediatric airway manikin.

The business operates as a contract manufacturer and specialized product company, generating revenue through quote-based B2B hardware sales and contract manufacturing services delivered via direct enterprise field sales to OEM customers. Sales offices are claimed on three continents, and the company provides end-to-end services spanning concept design, prototyping, manufacturing, assembly, and testing. There are no publicly disclosed pricing models, revenue figures, or external funding rounds; the company has remained family-owned since founding and is currently led by Kris Wyrobek, with approximately 101–250 employees. Customer acquisition relies on direct enterprise engagement, a corporate website, presence at medical simulation conferences (IMSH, SimGHOSTS, SimOps, SIM ONE, Anesthesiology Annual Meeting), and a dedicated e-commerce-style site for 7S3 simulation products.

Core offering

7-SIGMA designs, manufactures, and supplies high-performance polymer and metal components and assemblies for the printing, medical, aerospace, and industrial markets, providing end-to-end services from concept and design assistance through prototyping, manufacturing, assembly, and testing. The company operates an in-house polymer characterization laboratory (rheology, cure characteristics, TGA, DSC, FTIR) and specialized processes including liquid injection molding, Teflon and polymer/metal adhesion, and liquid silicone molding. Through its 7S3 Simulation Systems sub-brand, the company also sells modular high-fidelity airway training systems and medical simulation products to healthcare professionals.

Product overview

7-SIGMA operates as a dual-brand company with two distinct product portfolios. The primary brand is 7-SIGMA itself, a precision polymer and metal component manufacturer serving printing, medical, aerospace, and industrial markets with capabilities spanning design, engineering, manufacturing, and quality services. The secondary brand is 7S3 (7-SIGMA Simulation Systems), which provides modular high-fidelity airway skills trainers to the medical marketplace, including the flagship 7S3 Modular Airway Training System, Sensor-Based Bronchoscopy Trainer, Sensor-Based Novice Airway Trainer, and Mae pediatric airway manikin. The company's simulation products are targeted at healthcare professionals for airway management training, while the precision manufacturing division produces fuser rollers, pressure rollers, media path rollers for printers/copiers, and engineered components for medical devices, aerospace, and industrial applications.
