composite solutions for the industry's special needs

With our long and versatile experience in the composite industry, we develop and create tailor-made 3D models and shapes of different materials for the industry’s special needs.

MMI Company is ISO certified within quality, environment and safety.


We offer complete tailor-made solutions for the composite industry – planning, milling and vacuum infusion. Our goal is to create added value, better solutions and quality for our customers. We are constantly looking for faster and more environmentally friendly methods for our production.


Certification has been important in creating routines for our internal processes. The routines are created to minimize waste, reuse materials and work in a safe way – ”All the time with safety in focus”. We have undergone a process to create our own safety manual. Certification also enables the development of our own operations to include collaborations with larger companies and new industries.

"Vi har samarbetat med MMI i flera olika projekt sedan de startade sin verksamhet. Ett av de senaste projekten var utfräsning av skrovpluggen till vår nya SARGO 45. Som samarbetspartner fungerar MMI flexiblelt och målmedvetet. Vi kan rekommendera MMI och ser fram emot ett fortsatt samarbete även med nya projekt."
