FAQ
Q: What wire materials can be drawn with graphite dies?
A: Graphite dies are ideal for drawing copper, aluminum, brass, bronze, and other non-ferrous metals. They are not recommended for ferrous metals like steel due to chemical reaction at high drawing temperatures.
Q: How long does a graphite wire drawing die last?
A: Die life depends on wire material, drawing speed, lubrication quality, and die size. Typically, graphite dies last for several tons of wire production before re-honing is needed. Proper lubrication and cooling significantly extend die service life.
Q: Can you produce custom die geometries?
A: Yes, we specialize in custom graphite dies and guides. Please provide your wire drawing die drawings or specifications, including die angle, bearing length, and approach angle. We can produce dies matched to your specific drawing equipment and wire requirements.
