About Used Reciprocating Screw Blow Molding Machines

Reciprocating screw blow molding machines use a reciprocating screw (similar to injection molding) to plasticize and inject material into a parison die head. This provides excellent material homogeneity, precise shot control, and the ability to process a wider range of engineering resins compared to continuous extrusion machines. Reciprocating screw blow molders are used for technical parts requiring tight wall thickness control and consistent material properties.

Meadoworks stocks used reciprocating screw blow molding machines from Uniloy, Graham, and Milacron. Contact us at 800-323-0307.

Frequently Asked Questions

What is a reciprocating screw blow molding machine?

A reciprocating screw blow molding machine uses a screw that both rotates (to plasticize material) and reciprocates (to inject material into the die head), similar to an injection molding machine. This provides better material control and homogeneity compared to continuous extrusion, especially with engineering resins.
