Graphite Mold Tube for Copper Continuous Casting
Product Overview
Our precision graphite mold tubes are specifically designed for horizontal continuous casting of copper rods, tubes, and profiles. Made from high-density fine-grain isostatic graphite, these graphite molds provide excellent thermal conductivity, uniform solidification, and long service life for continuous copper casting operations.
We manufacture graphite mold tubes in various sizes and geometries for casting copper rod, copper tube, copper busbar, and custom profiles. Our graphite molds deliver consistent casting quality, smooth surface finish on copper products, and reliable performance for 24/7 continuous casting operations.

FAQ
Q: How long does a graphite mold last in copper continuous casting?
A: Typical service life is 50-200 tons of copper cast, depending on casting speed, copper grade, cooling conditions, and mold size. Proper mold preheating and cooling water management maximize mold life.
Q: Can you produce custom profile graphite molds?
A: Yes, we manufacture custom inner geometries for casting special copper profiles including rectangular, hexagonal, and custom cross-sections. Please provide your profile drawing and dimensions for quotation.
Q: Do you offer molds for brass and bronze casting?
A: Yes, our graphite molds are suitable for continuous casting of brass, bronze, and copper alloys. Material selection may vary based on casting temperature and alloy composition. Please specify your alloy for recommendation.
