Alternator, diode carrier   Industry Automotive Material Stanyl® TW241F10 - PA46-GF50   Processing Technology Injection Molding Description Reliable high temperature performance with easy processing AC/DC converters are used to convert the AC current, generated by the alternator, to DC (direct current) that all car electrical components work off. The alternator Diode carrier which is assembled to the AC/DC converter, is exposed to temperatures of about 200ºC due to energy losses in the conversion process. As the diode carrier is bolted onto a metal frame (heat sink), dimensional stability and creep resistance at 200ºC are very important. The part consists of a Stanyl carrier in which four phenolic bosses are inserted. Stanyl integrates these bosses and the carrier by a single step injection molding. At the specified conditions, PA66 and PBT were excluded as stiffness retention at the higher temperature was an important criteria. Compared to other high temperature materials like PES & PPS, Stanyl offered better processing and shorter cycle times and a lower overall cost. The high elongation at break of Stanyl offers excellent protection against thermal fatigue. Key Stanyl characteristics are: - High elongation at break - Excellent dimensional stability at elevated temperatures - Excellent heat distortion resistance OEM Ford, Fiat
