Rectifier

Industry
Automotive
Alternator is used for current switching in motor vehicle. The rectifier is one of the core components in the Alternator. It needs good electrical property and no crack issues caused by vibration. Besides that, optimal dimensional stability is needed as the part is over mold with metal inserts.}

Water pump part

Industry
Industrial equipment
This fin part is assembled with the impeller part (metal) inside the water pump. Furthermore, the dimensional stability and high rigidity and strength of Xytron are essential in this application.}
