What Trelleborg Sealing Solutions Detroit makes

Trelleborg Sealing Solutions Detroit, Inc. is the US legal entity through which Trelleborg Sealing Solutions runs a Detroit-area automotive engineering presence and a silicone manufacturing plant in Elk Rapids, Michigan. Its registered office sits at 15701 Centennial Drive in Northville, a suburb next to Plymouth in the Detroit metro. The broader Trelleborg Sealing Solutions business is a supplier of precision seals, bearings, and custom-molded polymer components: hydraulic seals, rotary shaft seals, O-rings, static seals, gaskets, oil seals, and pneumatic seals, built from elastomer, PTFE, polyurethane, silicone, and thermoplastic materials.

The Michigan footprint splits along two lines. Northville functions as an automotive engineering and test location. In 2022 the entity sponsored a Dyno Test Engineer position at the Centennial Drive address under a certified US labor filing, the kind of role that supports component testing for vehicle programs. The Elk Rapids plant is a 17,600 square foot precision manufacturing facility working in liquid and high-consistency silicone rubber, with molding, dipping, and heat-shrink processes run inside an ISO 8 cleanroom. That plant serves medical and specialty applications and, per the company, more than 30 years of silicone-materials experience sits behind it.

For automotive buyers, Trelleborg positions its sealing portfolio around OEM programs, including e-mobility and fuel-cell applications where sealing has to hold up against weight, temperature, and vibration targets. Because Trelleborg supplies at the Tier 1 level and molds custom polymer parts to print, the work typically runs through structured program-launch and PPAP discipline rather than catalog ordering.

Ownership and structure

Trelleborg Sealing Solutions Detroit, Inc. is a subsidiary within Trelleborg Sealing Solutions, one of three business areas of Trelleborg AB. Trelleborg AB is a publicly listed Swedish engineering group, traded on Nasdaq Stockholm under the ticker TREL-B, founded in 1905 and headquartered in Trelleborg, Sweden. The Sealing Solutions business area itself dates to 1952 and was built up through acquisitions, including the 2003 purchase of the precision seals business that became Trelleborg Sealing Solutions.

As a business area, Trelleborg Sealing Solutions reports roughly 8,500 employees across more than 35 manufacturing sites, 15 R&D centers, and 60-plus customer solution centers worldwide. It is the largest of the group's three business areas, accounting for close to half of group revenue. The Michigan operations covered here are one node in that network: a regional engineering and customer-facing presence in the automotive heartland, plus a specialized silicone plant. The Detroit, Inc. entity does not report standalone headcount or revenue, so those figures are shown at the group and business-area level rather than invented for the subsidiary.

Financial backing

Trelleborg Sealing Solutions Detroit does not publish its own financial statements, which is normal for a wholly owned operating subsidiary. Its resilience rests on the parent. Trelleborg AB reported net sales of approximately SEK 34.2 billion in 2024, with an operating margin of about 18.1 percent excluding items affecting comparability, and employed roughly 16,800 people across around 40 countries. Sealing Solutions is the group's largest segment by revenue.

Because the sub-entity carries no separate balance sheet or profit-and-loss statement, this profile does not assign it a financial-resilience or operating-trend grade. The published group figures above are the relevant backing signal: a listed parent operating at a double-digit margin at multi-billion scale.

Certifications and quality

The Elk Rapids facility operates ISO 9001 and ISO 13485 quality management systems, the latter covering medical device manufacturing, and runs an ISO 8 cleanroom for silicone component production. The company also states that its device and drug manufacturing work is licensed by the State of California at a Paso Robles site tied to the same operation. These are the certifications the company itself documents for the sites associated with this entity. IATF 16949, the standard automotive quality system, is common across Trelleborg's automotive plants but is not separately documented for these specific Michigan sites, so it is not claimed here.

Known customers

Trelleborg does not name specific customers for this entity, which is normal for a supplier of custom-molded and program-specific parts. Two relationships are documented by category rather than by name.

Nothing below the documented bar is published. The parent group serves automotive, aerospace, medical, and general industrial markets broadly, but named program-level customers for this specific subsidiary are not on the public record.

Sourcing evidence

No US import record is attributed to this entity. A large customs footprint does exist under the name Trelleborg Sealing Solutions, but it belongs to the group's US operating company headquartered in Fort Wayne, Indiana, a separate legal entity from the Detroit, Inc. company profiled here. Attributing those shipments to this Michigan entity would be inaccurate, so the customs band is left empty rather than filled with another entity's data.

That distinction matters for buyers using trade data to size a supplier. Bills of lading are filed against the importer of record, and a multi-entity group like Trelleborg concentrates its US imports under one or a few consignee names. The absence of a Detroit-entity customs record is a matter of corporate structure, not activity. For direct-materials teams weighing where seals and molded polymer parts are made and shipped, the relevant facts here are the Michigan manufacturing and engineering footprint and the publicly listed parent behind it, not a shipment count. Buyers evaluating nearshoring options for sealing components will find both domestic Michigan production and a global Trelleborg network to draw on.
