Founder
Mike Durina brings unparalleled expertise to plastic manufacturing quality systems 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 working for 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 and 18 employees to $22 million and 180 employees. In 1999, he founded Md Plastics Inc. with a deep understanding of plasticating unit importance in injection molding processes. Mike has been awarded eight patents with one pending, including innovations like the Melt Profiler™, Inject-EX™, Mini-Shut™, and MDP™ Performance Valve. His technical knowledge and disciplined approach to providing the right solutions has made Md Plastics a trusted partner for manufacturers seeking to enhance quality and profitability through innovative plasticating solutions and cutting-edge technologies.
Custom insert injection molding involves placing metal or other components into the mold cavity before injecting plastic, creating a single integrated part. This process requires precise temperature control, consistent shot size, and specialized equipment to ensure proper bonding and dimensional accuracy around the inserts without damaging them.
