Latest Belvac dome reduces scrap rate
Belvac Production Machinery Inc. has introduced a reduced-height design for its DT series of bottle-dome-trimming machines, as the company redesigns an industry standard, the double-ring dome.
Belvac said the innovation will help customers increase line speeds, improve quality and reduce material costs. The plastic bottle industry needs to reduce bottle weight, especially on wide-mouth PET containers, the company said.
The patent-pending ``lite dome'' design can reduce dome scrap by as much as 30 percent, according to Belvac.
The company in Lynchburg, Va., initially is targeting the wide-mouth PET sector, but the new dome also can be adapted to bottles made from polyolefin resins. It applies to the full range of DT dome trimmers, including those with speeds of up to 24,000 bottles per hour.

Westland now using Reiloy barrel blanks
Wichita, Kan.-based Westland Corp. is making bimetallic barrels using cast barrel blanks from Reiloy, a division of Reifenhauser Group of Troisdorf, Germany.
Westland will stock common sizes of Reiloy barrel blanks. The Reiloy blanks are free from distortion, eliminating the need for labor-intensive straightening operations and stress-relief annealing, the company said.
According to Westland, the wear-resistant Reiloy barrel blanks have a good reputation in Europe and Asia, but they have not been easy to get in the United States.

PSI-Polymer touting high-pressure pump
PSI-Polymer Systems Inc. said its high-pressure gear pump is designed to process highly viscous, filled materials, while operating at up to 10,000 pounds per square inch and at temperatures of up to 600° F.
For PSI of Hickory, N.C., the HGP is an addition to its existing gear pump line. The company's extrusion gear pump operates on extrusion lines with pressures of up to 5,000 psi.
Mounted between the extruder and the die gear, the HGP accurately meters the polymer and pressure from the extruder to the die, the firm said.
Typical applications include sheet, coatings, pipe and profile, wire and cable, tubing and blown and cast film.
All parts are manufactured to ISO 9002 standards. The heavy-duty, high-pressure gear pump features through-hardened tool-steel gears and a pressure-balanced drive shaft.

Busch vacuum pump is low-maintenance
Busch Inc.'s compact vacuum pump, the MM, is good for evacuating extruder barrels, since it has a higher, more-constant vacuum than liquid ring pumps, according to the company in Virginia Beach, Va. Another benefit: The design eliminates water contamination.
Vacuum is provided by two noncontacting, claw-type rotors in an oil-free chamber. Because of the noncontacting design, there is no wear in the pumping changer, which means low maintenance. The pump uses less electrical power, the firm said.

Davis-Standard pump can improve testing
Davis-Standard Corp. said its KXE filter pressure value (FPV) pump improves the quality-control testing of compounds, especially color compounds, with accurate, repeatable pressure control.
Filter pressure value quantifies the level of resin dispersion. The value helps compounders maintain product consistency and provides a standardized way to compare one product with another.
Davis-Standard of Pawcatuck, Conn., said the FPV pump is more repeatable than the ASTM method previously used.
The pump is available as an integrated component on a new laboratory extruder, or as a stand-alone unit with an existing extruder.

Scanner can gauge all multilayer films
Battenfeld Gloucester Engineering Co. Inc. said its O-Frame Scanner uses a fixed beta gauge for noncontact measurement of multilayer film that is effective with all barrier resins, regardless of film temperature.
The O-Frame Scanner provides real-time control through Battenfeld Gloucester's Extol process controller.
It mounts between the oscillating haul-off and the secondary nip, measuring the collapsed lay-flat film.
The beta gauge is enclosed in the rectangular O-Frame, through which the film passes before separation.
The sensor scans both sides of the film and begins sending data after a 90-degree rotation of the haul-off.
The company said conventional fixed-gauge sensors need a complete 360-degree rotation of the oscillating unit before they can calculate thickness and transmit data, and that can take as long as 20 minutes.
The company in Gloucester, Mass., said the O-Frame Scanner can be piggybacked to different sensors such as infrared or nuclear sensors, which supply data on the thickness of barrier layers.
