Frequently Asked Questions

What makes MD Plastics' plasticating systems different from conventional reciprocating screw systems?
Our patented systems eliminate deficiencies of traditional technology through stationary screw designs, providing consistent output-recovery time and ensuring each pellet experiences the same heat and shear history for superior part quality.
How do your non-return valves improve injection molding performance?
Our MDP™ Performance Non-Return Valves feature the lowest pressure drop in the industry, precise shutoff capability, and extended wear life of 6-7 years, resulting in improved hydraulics and consistent shot-to-shot part quality.
Can your plasticating screws work with all polymer types?
Yes, our Posi-Melt™ screws are designed to process all polymer types from LCP to HDPE, LDPE, PS, PET, ABS, and more. They increase plastic exposure to the barrel wall by up to 60% for superior melt homogenization.
What size range do your plasticating components cover?
Our components accommodate a wide size range: barrels from 14mm to 250mm ID bore size, screws from 14mm to 240mm diameter, and valves from 14-260mm diameter, ensuring compatibility with most injection molding machines.
How do your automatic shut-off nozzles eliminate drooling and stringing?
Our Mini-Shut™ nozzles feature patented technology that shuts off instantaneously when melt flow stops, preventing material escape while allowing free flow with minimal pressure loss, eliminating the need for melt decompression.
Do you provide custom design services for specific applications?
Yes, company owner Mike Durina personally provides custom design consultation for specific machine makes and models, utilizing proprietary design software to optimize components for your exact resin and process requirements.
What warranty and support do you offer with your plasticating systems?
We provide comprehensive technical support including application review, installation guidance, and performance evaluation. Many of our components, like the MDP™ valve, offer extended wear life with documented cases of 6-7 years of operation.
