Two beside-the-press granulators from Conair Martin in Agawam, Mass., the LP and JC series, have been redesigned with smaller footprints. LP granulators have an open-top feed hopper for meter feeding by robot or conveyor, sprues, runners or lighter-weight parts. Conair said the smaller size and a low feed hopper height make the LP suitable for closed-loop use with robots. Four LP models are offered with hopper openings from 12 by 14 inches to 18 by 21 inches. Throughputs range from 100-300 pounds an hour.
JC granulators are designed for batch-fed parts and runners made from hard-to-cut engineering resins and thick parts and runners. Hopper openings are from 7 by 8 inches to 10 by 21 inches, with throughputs up to 1,000 pounds an hour.

Herrmann enhances ultrasonic welders
Herrmann Ultrasonics Inc. of Schaumburg, Ill., has a new line of ultrasonic welders.
Called Effective, the computer-controlled welders include a feature that helps optimize the weld and the ability to program amplitude from 70-100 percent. A new generator provides contact amplitude output regardless of variation in voltage from 190-240 volts.
The operator is able to see the actual melting process through a joining velocity graph, which displays the traveled weld depth vs. weld time.

BASF Ultradur grades help reduce warpage
BASF Corp. Plastic Materials' new glass-fiber-reinforced polybutylene terephthalates offer improved processing and surface appearance, the Mount Olive, N.J., firm claims.
The Ultradur S grades have reduced warpage, high-melt flow and good dimensional stability.
BASF said they also are about 4 percent less dense than comparable PBTs, allowing cost savings.
Ultradur S 4090 G4 is 20 percent glass-reinforced, and 4090 G6 has 30 percent glass-fiber content. Light housings, motor housings and electrical connectors are among targeted applications for the compounds made at the company's Wyandotte, Mich., plant.

Entoleter announces precision film cutter
Entoleter Inc. of Hamden, Conn., offers a line of precision film cutters designed specifically for film and fiber scrap.
Throughput for film is up to 6,000 pounds an hour. Film is cut by ``scissor'' action instead of tearing because the knife is at a uniform setting across the entire length of the cut. The unit uses standard, off-the-shelf screens that drop away from the chamber for easy cleaning.

MOtoman robot now slimmer, stronger
Motoman Inc. of West Carrollton City, Ohio, said its newest six-axis robots boast a slimmer arm, a thinner waist and a more compact, in-line wrist than competing robots.
The SK120 is suited for material handling or spot welding. It has a maximum reach of 102 inches and can carry up to 265 pounds. Repetitive positioning accuracy is 0.016 inches.

Cryovac touts films for pmupable foods
Cryovac Division of W.R. Grace & Co. of Duncan, S.C., unveiled a family of film products for hot- or cold-filled foods.
The FS 5000 series is multilayer coextruded polyolefin that features increased strength and flexibility from 212§ F to minus 20§ F.
The company claims oxygen and moisture barriers assure flavor protection of pumpable, hot-or cold-filled foods, and high-integrity seals made of the materials can withstand the rigors of handling and distribution.
