(Pawcatuck, Conn.)--Davis-Standard, in conjunction with Sumi Texas Wire of El Paso, Texas, recently designed its first "high capacity" extrusion system for manufacturing primary automotive wires in North America. This system will be used for producing wires supplied to harness manufacturers, which will then be installed by North American automobile makers. This was the sixth Davis-Standard extrusion system purchased by Sumi Texas Wire, a

Davis-Standard customer of more than five years.

At the heart of the system is a 2-inch (50mm) grooved feed extruder. This extruder is used for the main coating of the wire and is capable of processing flexible PVC pellets at a rate of 300 pounds per hour (135 kg per hour). Typical processing rates for conventional smooth bore extruders are 120 pounds per hour (54 kg per hour). This output increase does not compromise melt temperature or resin plastification, and extruder outputs are more linear.

"The process of coating primary automotive wires is an ideal application for a grooved feed extruder," said John Zachow, Business Area Manager of Davis-Standard’s Wire and Cable Systems Group. "This is primarily due to the fact that greater throughputs can be achieved on smaller extruders. Pelletized flexible PVC and polyolefins also help make this application ideal."

This system is the second sold by Davis-Standard in 2002 that offers this refined technology. For more information, contact John Zachow at jzachow@davis-standard.com.
