CFC fixtures by Graphite Materials withstand heat of up to 1,300 °C, tremendous temperature fluctuations and a high weight load and still stay "in shape". This makes them the ideal workpiece fixture for use in heat treatment, for example, when hardening metallic components. Application: Auto,Precision Gear,Heattreating industries,such as ferritic nitrocarburizing and nitriding to gas carburizing, oil quenching and even air tempering.
Resistance to high temperature: Up to 2000ºC.
CFC tooling (also called Carbon Fiber Composite) has been employed allowing significant benefits in heat treatment industry, of which weight reduction is a major benefit. However,depending upon the heat treatment or surface engineering process-there are additional benefits to CFC tooling.
The most important features of CFC versus alloy are:
• CFC fixtures are much stronger at high temperature condition.
.CFC fixtures retain their precision shape during heating,quenching,and over time (no alloy creep).
CFC fixtures can be coated to prevent oxidation and oil degradation.
CFC fixtures are around 10-20% of the weight of alloy
Heat treatment industry is changing, and it is changing rapidly. Advances in furnace designs and fixturing are opening up new ways of thinking. Precision fixtures like CFC allow weight reduction, long life, and precision load building. Furnaces take up valuable plant floor space, so methods need employed that maximize their use. Critical parts, like gears, demand precision tooling which only CFC can offer. CFC is lighter, stronger at temperature and keeps its shape even after the abuses it sees with years of use in a furnace environment. Combining all these benefits of CFC tooling, the savings may far exceed the initial capital cost premium and should be considered, especially with today's modern furnaces.
