Industry pioneer with decades of plasticating expertise.
Founder
Mike Durina founded Md Plastics Inc in 1999, bringing decades of specialized expertise in plasticating technology to the industry. He holds an AAS in Plastic Engineering from Ferris State University and a BS in Industrial Engineering from Kent State University. From 1978 to 1984, Mike worked for three separate injection molding firms, gaining hands-on experience across multiple roles. In 1984, he began a transformative 16-year career at Spirex, where as VP of Sales & Service, he grew the company from $1.8 million in sales with 18 employees to $22 million with 180 employees. This experience deepened his understanding of the critical importance of plasticating units to injection molding success. Since founding Md Plastics, Mike has been awarded eight patents with one pending, developing innovative products including the Melt Profiler™, Inject-EX™, Mini-Shut™, and MDP™ Performance Valve. His commitment to advancing plasticating technologies has positioned Md Plastics as a trusted partner for injection molders seeking enhanced quality and profitability.
What types of materials can your custom screws process?
Our custom-designed Posi-Melt™ screws and extrusion screws are engineered to process virtually any thermoplastic material, including commodity resins, engineering polymers, medical-grade materials, moisture-sensitive resins, filled compounds, and liquid silicone rubber (LSR). We analyze each material's melting point, thermal sensitivity, shear sensitivity, flow characteristics, moisture absorption, and additive interactions to design the optimal screw geometry, compression ratio, and surface treatment for your specific application.
