Wayne Machine & Die Co. of Totowa, N.J., has introduced a series of extruders with a design for crosshead die applications such as wire insulation, cable, tubing, fiber-optic sheathing and yarn or filament coating. The barrel protrudes an extra 20 percent from the base for easy setup and access to the die for adjustment.
Each extruder may be outfitted with a universal barrel for handling all polymers, from standard polyethylene to fluoropolymers, and a series of optimized screws suited to specific polymers.
Wayne also introduced a strand pelletizer to produce micropellets, very small pellets for small extruders or for situations that require pellets that melt quickly and easily. Line speed can be adjusted while maintaining constant pellet length.

GE touts savings of reusable PP sack
GE Plastics' new Gepsac packaging for engineering thermoplastics should lower costs and improve productivity compared with cardboard boxes.
Gepsac is a reusable 55-cubic-foot woven polypropylene sack with a low density polyethylene liner. Its 2,200 pounds of capacity is twice that of standard boxes. An official with the Pittsfield, Mass., resin supplier estimated cost savings of nearly $300 per truckload after eight months of use.

Machinery firm IMS unveils new products
IMS Co. of Chagrin Falls, Ohio, is offering three new products.
A High-Range Dewpoint Meter is used to check the output of hot-air or refrigeration-type hopper dryers. The range on the new digital Model 8074 is 10§-70§ F.
IMS now stocks a closed-loop Temperature Control Module with a digital amp-draw and temperature display. The user pushes a button to get a reading on the amperage.
A Floor-Level Gaylord Tipster now has a safety ratchet to keep the platform from crashing down if the pneumatic system loses air pressure. The device tips a gaylord to maintain a steady supply of material to a pickup tube.

Harrel introduces new tubing process
Harrel Inc. says its Alternate Polymer extrusion system allows a processor to automatically vary composition of tubing, a profile, film and other extrusions along the length or cross section.
Harrel's AP-600 system can change hardness or other properties through blending of two or more components during the extrusion process. Medical tubing, for example, can comprise 100 percent material ``A'' at one end, gradually changing to 100 percent material ``B'' at the other end. The East Norwalk, Conn., firm will supply a turnkey system designed with a high degree of systems control and special extruders and downstream equipment.
