Trelleborg further extends position in the aerospace industry

Trelleborg, Sweden –Trelleborg Sealing Solutions has signed an agreement to acquire US-based Tri-Mack Plastics Manufacturing Corp., parent Trelleborg Group announced 21 Oct.  

Expected to be completed during the first quarter of 2027, the acquisition strengthens Trelleborg’s position in the supply of thermoplastic parts & systems for the aerospace industry.

Bristol, Rhode Island-based Tri-Mack also expands the Swedish group’s capabilities in advanced composites and polymer components for airframes and aircraft engines.

With 2025 sales of around SEK300 million (€27 million), the US company operates a “vertically integrated” plant equipped with advanced automation, robotics and in-house toolmaking capabilities.

In addition to aerospace applications, Tri-Mack manufactures components and solutions for semiconductor equipment and industrial gas turbines, added Trelleborg.

 “Tri-Mack operates in an attractive growth segment within the aerospace industry, where demand for thermoplastics composite materials is increasing,” said Jürgen Bosch, president of Trelleborg Sealing Solutions.

Demand for its products is “driven by requirements for lower weight, shorter manufacturing lead times and improved cost efficiency,” Bosch added in the Trelleborg press release.

Concluded the statement: Tri-Mack is an “important addition to the aerospace platform that Trelleborg is building through its previous acquisitions of Aero-Plastics and Magee Plastics.”
