Founder
Mike Durina brings exceptional expertise to plastics manufacturing with an AAS in Plastic Engineering from Ferris State University and a BS in Industrial Engineering from Kent State University. His career began in 1978 across three injection molding firms before joining Spirex in 1984, where he served as VP of Sales & Service for 16 years. Under his leadership, Mike grew Spirex from $1.8 million in sales with 18 employees to $22 million with 180 employees. His deep understanding of plasticating units and their critical role in injection molding led him to found MD Plastics in 1999. Mike has been awarded eight patents with one pending, demonstrating his commitment to innovation in plastics processing technology.
