MME Group

What MME Group does

MME Group, Inc. is a full-service injection molder and contract manufacturer headquartered at 1185 Willow Lake Blvd in St. Paul, Minnesota, with a complementary tooling and development facility in Vadnais Heights. Originally founded in 1974 as Minnesota Mold and Engineering, the company transformed into its current contract-manufacturing form around 2000 and now operates 24/7 across three shifts, employing 100+ people across more than 100,000 square feet of manufacturing space, including a 30,000 sq ft ISO Class 7/8 cleanroom. MME is vertically integrated across the full product lifecycle: engineering (FEA, DFMA, design control), in-house tooling design and build, plastic and silicone injection molding using 10–750 ton presses (including five LSR presses at 44–165 tons and two-shot/overmolding/insert molding), secondary operations (ultrasonic welding, gluing, automated screwing, in-house laser marking), value-added assembly, quality systems, packaging, and supply chain logistics. Differentiated capabilities include Two-Shot Injection Molding, LSR molding in a cleanroom environment, and an active program-transfer service that has executed more than 200 complex part and product transfers.

The company serves three primary verticals: medical devices (the dominant segment, including surgical instruments, implants, respiratory masks, fluid handling systems, and FDA-cleared components for customers such as 3M, Vascular Solutions, Apollo Endosurgery, Hans Rudolph, and 3B Medical), highly regulated / ITAR-registered defense and government customers, and consumer products (e.g., Nebia/Moen showerheads, HurryCane walking canes, Rachio smart sprinkler controllers, Xalt overmolded busbars). MME's regulatory stack — ISO 13485:2016, FDA registration (3006535109) compliant with 21 CFR Part 820, ITAR (M34528), UL/CE/TUV, and ISO Class 7 Cleanroom — is the central enabler for its medical and defense customer base. Revenue is generated through project-based, custom-quoted contracts covering engineering, tooling amortization, molding, assembly, and logistics, with multi-year programs typical.

On September 30, 2022, MME was acquired by Seaway Plastics Engineering, which itself had been acquired by ICG (Intermediate Capital Group, LSE: ICP, $71.3bn AUM) in June 2022. The transaction combined MME into a platform of more than 240,000 square feet across Florida, California, and Minnesota, with ICG's North American Direct Private Equity team positioning medical device manufacturing as the core growth vertical. MME continues to operate as a division of Seaway under its existing leadership, with Bob Archambault (President & CEO), Rogelio Marin (VP & GM), Dave Mercer (CFO), and Tom Schrupp (Director of Business Development) leading day-to-day operations.

Direct peers

• Seaway Plastics Engineering: MME Group's parent company since September 2022 and itself a leading provider of injection-molded engineered components. Operates the combined 240,000+ sq ft, five-facility network spanning FL, CA, and MN, with overlapping medical device and regulated-industry customer base.
• Tessy Plastics: Skaneateles, NY-based custom injection molder and contract manufacturer serving medical device, diagnostics, and industrial customers. Comparable vertical-integration model with in-house tooling, molding, and assembly, and similar reliance on FDA-regulated programs.
• Avalign Technologies: Medical device contract manufacturer specializing in precision-machined and molded implants, instruments, and delivery systems. Comparable medical-device customer base and regulated-manufacturing credentials (ISO 13485, FDA-registered).
• Mack Molding: Arlington, VT-based custom injection molder and contract manufacturer with deep medical and industrial customer mix. Operates in-house tooling, molding, and assembly services similar to MME's vertical integration.
• UFP Technologies: Public medical and specialty packaging/manufacturing company (NASDAQ: UFPT) producing molded components for medical devices, wound care, and protective packaging. Comparable in serving regulated medical OEMs with engineered, custom-molded solutions.
• Crescent Industries: New Freedom, PA-based custom injection molder with ISO 13485 certification serving medical, dental, and industrial markets. Comparable in offering in-house tooling, cleanroom molding, and assembly for regulated OEM customers.
• NPI Medical (NetShape Partners): Medical device contract manufacturer with ISO 13485 certification, offering injection molding, insert molding, and assembly for medical OEMs. Comparable scale and medical-device vertical focus to MME.

Broad incumbents

• Protolabs: Public digital manufacturer (NYSE: PRLB) offering rapid injection molding, CNC machining, and 3D printing. Competes with MME on prototyping and low-volume production but serves a broader customer base and lacks MME's medical cleanroom specialization.
• Stratasys: Public 3D printing and additive manufacturing leader (NASDAQ: SSYS). Provides complementary prototyping and low-volume production capabilities that overlap with MME's bridge/prototype tooling services for medical OEMs.

Emerging players

• Plastic Molded Concepts: Eagle, WI-based custom injection molder with growing medical device focus, including cleanroom capabilities. Smaller and more regionally focused than MME but competes for similar mid-market medical OEM programs.
