Introducing our Copper Mold Tube, the perfect solution to the problem of copper tubes separating from the ingot shell during the cooling process. Designed with a square or rectangular shape that bends to one side, this crystallizer copper tube features a tapered interior from top to bottom, with a double or triple or multi-cone shape or a parabolic shape. The taper at the top is greater than the taper at the bottom, ensuring a snug fit between the ingot shell and the tube walls, in line with the ingot shell's contraction patterns. With our Copper Mold Tube, you can avoid the risk of air gaps forming between the ingot shell and the tube walls, ensuring a smooth and efficient working process. Trust our Copper Mold Tube to deliver exceptional results every time.
