O.S. Walker bolts clamps magnetically
O.S. Walker, a subsidiary of Walker Magnetics Group Inc., has introduced a magnetic mold-clamping system designed for thermoforming machines.
Pressmag QMC bolts directly to the machine's platen. Walker's ``electropermanent'' magnet design needs no power during operation.
O.S. Walker of Worcester, Mass., said the magnetic mold system can be added without modifying the existing molds or machine.

Industrial Sensors offers new products
Industrial Sensors Inc. of Winchester, Mass., introduced four new sensors, pressure indicators and gauges recently.
A melt-pressure sensor, with no transmission fluid, uses a high-temperature strain gauge at temperatures as high as 350° F.
Microprocessor-based melt- pressure indicators show pressure and temperature readings in an easy-to-read, five-digit display. Also new are digital melt-pressure gauges and a melt-pressure sensor for extrusion.

CDS separator deters water contaimination
CDS Technologies Inc. of Rosell, Ga., is selling environmental peace-of-mind — a separator that can remove plastic pellets from factory storm water.
Water flows into the unit and down through a separation screen. Solids get pushed to the center, and fall into a sump area, while liquid passes through special nonclogging screens and out.
