CHICAGO (July 31, 2:10 p.m. EDT) — Xaloy Extrusion is showing a new pneumatic screen changer with no hydraulics or electrical controls to maintain. It relies on the plant air supply to index the slide plate. Fully guarded for safety, it comes in three sizes for 2½- to 4½-inch extruders.
New, continuous screen changers now come in a space-saving vertical configuration. Like the firm's horizontal models, the vertical ones use dual breaker plates for increased filtration area. Sizes range to 9.1 inch.
Xaloy's new Fusion II screw delivers superior mixing and high productivity, the New Castle, Pa., firm claims. It provides enhanced chaotic mixing while keeping the productivity of faster plastication and lower melt temperature of the original Fusion screw. The screw is suited to extrusion, injection molding and blow molding.
Other new Xaloy Extrusion products announced at NPE 2006 include: manual screen changers that fit standard metric extruders; two new melt pump sizes, and new LAS 4000 liquid additive systems with minimal loss in throughput.
Xaloy Inc. is introducing new components for injection molding.
The Xaloy JCP Jet Cleaner oven removes polymer buildup from screws up to 60 inches long using vacuum pyrolysis. Eleven oven sizes are available.
New upsize/downsize packages help molders achieve optimum shot size for existing presses, the firm said. Each unit is ready to install.
The Posi-Melt injection screw is an alternative to general-purpose screws. It delivers more output at lower temperatures and provides better mixing and a wider processing window, according to the company.
