plasticator
nounEtymology From plastic + -ator.
1
A device for melting and mixing thermoplastic materials.
- In the first-stage plasticator the screw motion generates controllable low pressure [usually 50 to 300 psi (0.34 to 2.07 MPa)], which causes the screw to retract slightly, preparing the melt to enter the second stage.2000, Dominick V. Rosato, Donald V. Rosato, Marlene G. Rosato, Injection Molding Handbook, →ISBN, page 151:
- An extruder, consisting of a rotating flighted shaft in a stationary barrel, is a well-known plasticator for its inherently efficient and effective energy transfer and positive displacement.2006, Shau-Tarng Lee, Chul B. Park, N. S. Ramesh, Polymeric Foams: Science and Technology, →ISBN, page 73:

- Fiber/resin pellets are gravity or machine fed through a hopper into the low-shear plasticator. The plasticator is maintained above the melting point of the thermoplastic polymer; the molten mass interacts with the screw of plasticator.2011, Uday Vaidya, Composites for Automotive, Truck and Mass Transit, →ISBN:
