Future Design offers single-lip air ring
Future Design Inc. of Mississauga, Ontario, developed its single-lip Saturn Titan air ring for running high-molecular-weight, high density polyethylene resins.
The Saturn Titan chamber develops the best possible airflow distribution to create a combination of volume and velocity to suit HMW-HDPE film. The single-lip design maintains the control to produce a range of stalk heights, gauge control and bubble geometry.
The air ring can be retrofitted to any system, with or without internal bubble cooling.

Dynaloy Inc. touts mixing-head cleaner
Dynaloy Inc. said it has a user-friendly cleaning system for polyurethane mixing heads during production.
The first step is a solvent that introduces a ``coating'' into the pores of the mixing-head surface. The coating provides a molecular layer that creates a smoother surface on the dispenser parts. The second step involves a solvent flushing that removes any remaining PU from the head.
The solvent does not leave behind a significant amount of residue, the company said.
Dynaloy of Indianapolis said its new technology works as well as methylene chloride and acetone flushing solvents.

Synventive hot runners provide dual heaters
Synventive Molding Systems Inc. said its new MultiZone hot runner, which uses heaters on both sides of the manifold to distribute heat more evenly, now is available for delivery in as little as four or five weeks.
MultiZone accommodates parts of any size and runs virtually any engineering resin, according to Synventive of Peabody, Mass.
The hot-runner system can be ordered as an assembled ``hot'' half, fully wired and tested and ready to install into an existing mold. Customers can engineer their own hot-runner systems with Synventive's help.

BKG pelletizer reliable for glass-fiber content
An underwater pelletizer from BKG Bruckmann & Kreyenborg Granuliertechnik GmbH is designed for glass-fiber-filled material.
According to BKG, the difficulty was not cutting the product, but the wear that happened during transportation and drying of the pellets. So the company invented a special centrifugal dryer, and developed new coating methods for the pelletizing system.
The pelletizer can handle 5,500 pounds of material an hour. The new system has proved reliable for polypropylene, polycarbonate and nylon with glass-fiber content of up to 50 percent, according to the company in Muenster, Germany.

Wallmaster suited for narrow tubing
Zumbach Electronics Corp. is targeting companies that make small-diameter medical tubing and catheters, with its Wallmaster extrusion controller.
Wallmaster is suited to products with diameters as small as 0.010 inch and with walls as thin as 0.004 inch.
The system automatically controls both diameter and wall thickness.
The unit can measure coextruded tubing with five layers.
Zumbach is based in Mount Kisco, N.Y.

ATI system provides broader inspections
Advanced Technologies Inc. of Palm Harbor, Fla., said its Spectrum vision system can inspect 7,200 parts per minute, using 12 cameras.
In plastics, Spectrum is used to check bottles, caps, lids and vials, housings, assemblies and automotive components, among other products.
The user can define exactly what is and is not a defect. Spectrum also produces multiple product tables, allowing for instant changeovers between different styles of products.
Spectrum also gathers statistics to allow the user to see the types, locations and number of defects. Alarms sound to alert an operator to defects.

CMT composite foam uses microspheres
CMT Materials Inc. claims its new composite foam, called Hytac-B1X, makes better thermoforming plugs than competing materials. The plugs are used to make molds for thermoforming.
The foam is a mix of engineering thermoplastics filled with hollow glass microspheres. It combines low thermal conductivity, low specific heat and coefficient of thermal expansion, high impact resistance and easy machining, the Attleboro, Mass., company said.
