These Irish contract manufacturers primarily serve the medical, automotive, and industrial sectors, with a strong presence in plastics, packaging, and precision engineering. Companies range from established firms like Bimeda, a veterinary pharmaceutical company founded in 1960, to more recent additions such as ABCD Engineering Ltd, a producer of stainless steel products established in 2008. IPL Schoeller, with 2704 employees, designs and manufactures reusable packaging solutions.
Other notable companies include Creganna Medical, a global leader in medical device design and manufacturing, and Mergon Group, which produces high-quality plastic components. Technimark specializes in GMP Cleanroom molding and assembly, while Takumi Precision Engineering Limited provides engineering solutions for medical and aerospace components. A common pattern is the distribution of headquarters across various towns, including Galway, Castlepollard, and Limerick, rather than a single dominant city.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
