Manual Screen Changers


From the worldwide leader in filtration equipment, Jinhua Machinery offers the EM and XM manual screen changers
Contamination of the melt steam by metal, wood, paper or internally generated black specks yields products that are unacceptable in appearance and/or performance. Manual screen changers are the least expensive and most suitable option for processes that require infrequent changes. Jinhua Machinery manual screen changers minimize costly downtime for screen replacement. With a simple swing of the handle lever during routine shutdown, clean screens are quickly brought on-line. No line disconnection occurs, and full production is re-established. As an option the EMP and XMP models add air assist to the shifting of the slide plate.

Integrate the System
Put an Jinhua Machinery melt pump after the screen changer and further increase the productivity of the extrusion line – all from one company.

Polymer Rheology Testing
Jinhua Machinery has the ability to provide polymer viscosity and melt index analysis.
