Milacron Extrusion sells new feed screws with a variety of options available. Feed screws are typically made of 4140 steel, polished, and hard faced with either Colmonoy 56 or 83. They can also be chrome plated or surface treated with a carbide encapsulation for more abrasive or demanding applications. In addition we offer several design options such as conventional or barrier, with mixing options such as straight Maddock, spiral Maddock, and Pineapple. We are capable of handling requests of any size, application, and complexity.

Milacron Extrusion sells vented and non-vented barrels. Barrels are typically made of JP38/BM32 equivalent steel. We offer clamp-type, bolt-on, or threaded discharge flanges. Barrels are centrifugally cast with bi-metallic liners of Nickel-Boron or Tungston-Carbide. Rupture disc and pressure transducer holes are pre-drilled at the factory and thermocouple holes can either be pre-drilled or drilled on site.

Our power to engineer solutions is the result of combining local expertise with a global team of the best that the industry has to offer across three businesses Advanced Plastics Processing Technologies Melt Delivery and Control Systems Fluid Technologies. Our 5,000 employees run the full gamut of plastics processing technology and experience.  Their expertise covers: injection, co-injection, extrusion and blow molding; hot runner systems and mold technologies; process control, fluid technologies and life-cycle management.

We have built a team that can deliver the entire spectrum of services that the plastics industry can offer.As it turns, it tries to screw itself backward out of the barrel, but a bearing keeps it from going out the back. Because every action has a reaction—remember Isaac Newton?—it pushes the other way, too, in the forward direction, and that’s what pushes the material out of the die.
