Xaloy technology aids extruder darrels
Production technology developed by Xaloy Inc. of Pulaski, Va., reduces stress and cuts delivery time of barrels for single-screw extruders. Patents are pending. Xaloy said it uses the process in barrel production. The technology uses a proprietary structural steel and improved casting and temperature control and handling techniques. Xaloy said a proprietary steel, BM-32, is used for the structural casing. Wear-resistant alloys are cast into the structural casting to produce bimetallic barrels.
Lower stress is the main im-provement, said Shiao Feng Chou, chief scientist at Xaloy. It results in a straighter barrel coming out of the casting furnace, reducing the amount of stress introduced in the straightening process.
The firm said BM-32 steel also makes casings with 25 percent greater toughness and better weldability than standard ANSI 4140 steel. The new process also permits shorter cycle times.

Clamping system cust cycle times
Branson Ultrasonics Corp. of Danbury, Conn., unveiled an automatic pneumatic system for clamping parts to be ultrasonically welded. An optional mechanism automatically ejects the parts.
Manual part clamps add time to the processing cycle. The clamping fixture is custom-designed to hold a specific part.
An operator places the part in the fixture. Two air cylinders engage to clamp the part.
Branson said the method uses manual part clamps.
