Torlon®, Aurum®, and Ryton® Picker / Stripper Fingers
for Business Machines
Attention to tool design for optimized tip geometry

Allegheny produces a range of Picker Fingers in a variety of high temperature materials including TorlonÒ PAI, AurumÒ TPI and RytonÒ PPS. These components work almost exclusively in the high temperature area in the Fuser section of the equipment. Ambient temperatures in this area of the machine reach 220° C (428° F) and therefore the materials used must be able to maintain a high degree of strength and dimensional stability. Fluoropolymer based coatings are applied to the tips to help with toner release and frictional concerns where the tip interfaces with the fuser roll.

Over the years Allegheny has evolved an expertise in the manufacturing processes required to produce Picker Fingers of the highest quality. Attention to tip geometry and true position are critical to the correct functionality of these components together with overall dimensional precision and workmanship. This inherent expertise starts with the design of the tool. It is critical to ensure that the tip is controlled to give a precise and consistent radius, free of all flash and mold witness lines that may otherwise interfere with the movement of the paper over the Picker Fingers.
