| In conjunction with Sumi Texas Wire, USA, the American company Davis-Standard, has recently designed its first �high-capacity� extrusion system designed for manufacturing primary automotive wires. This system will be used for producing wires supplied to harness manufacturers, which will then be installed by North American automobile makers. The new system includes a 50mm grooved feed extruder that is used for the main coating of the wire and is capable of processing flexible PVC pellets at a rate of 135kg per hour. This output increase does not compromise melt temperature or resin plastification. Furthermore, extruder outputs are more linear.
�The process of coating primary automotive wires is an ideal application for a grooved feed extruder�, commented Mr 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�.
