TriMas announced that it has signed an agreement to acquire the operating net assets of Weldmac Manufacturing Company, a designer and manufacturer of high-performance metal-fabricated components, welding, and assemblies for the aerospace, defense, and space launch end markets.

Weldmac operates CO2 and Y.A.G. lasers as part of it’s comprehensive in-house capabilities. Laser welding equipment offers fast, precise, and repeatable results unmatched by other means.
“The Weldmac acquisition represents a major step forward in advancing our strategic plans to expand our complex engineered solutions offerings in the space and defense markets, as well as adding to our already broad capabilities that include component and system design, custom tooling fabrication, welding, bending, forming, machining, mechanical assembly, metal surface coatings, and non-destructive testing,” said John Schaefer, president of TriMas Aerospace.
Offering numerous AS9100D and National Aerospace and Defense Contractors Accreditation Program (NADCAP) certified manufacturing services, Weldmac’s comprehensive processes include welding, stamping, punching, hydroforming, forging, laser cutting, custom tooling and machining, as well as advanced quality control inspections and complex assembly using various metals.
TriMas manufactures a diverse set of products primarily for the consumer products, aerospace, and industrial markets through its TriMas Packaging, TriMas Aerospace, and Specialty Products groups.
“We are excited to announce the agreement to add Weldmac to the TriMas family of businesses,” said Thomas Amato, TriMas president and CEO. “This acquisition will add complementary, highly-engineered products and new manufacturing capabilities to TriMas Aerospace, expanding our offering and position in the aerospace, defense, and space launch end markets.”
Located in El Cajon, California, Weldmac’s manufacturing complex is equipped with a wide variety of state-of-the-art lasers, metal forming and fabrication equipment. The company currently operates as a private, family estate-owned company, and generated approximately $33 million in revenue in fiscal year 2022.
“We expect Weldmac’s customers to benefit from TriMas Aerospace’s broader product offering, added innovation and manufacturing depth, while TriMas Aerospace’s customers will enjoy additional product offerings and capabilities provided by Weldmac,” added Amato.
Upon closing, which is anticipated to occur in the coming months, Weldmac will become part of TriMas Aerospace group and further advance the strategic growth of its integrated structural solutions product lines comprised of RSA Engineered Products and Martinic Engineering.
