Heat shrink tube sectional expanding machine

Heat shrink tube sectional expanding machine:The sectional expanding equipment includes rotary oven, tube cutting device, expansion molds, inflator, cloth bags and cooling device. The rotary oven is used to heat the heat the tube. After heating, the tube is evenly expanded in the expansion mold by the inflator and the cloth bag, and then formed after cooling. The tube cutting machine is used to trim the size of the tube, and the incision is more neat. By this method when the tube is expanded, the force on each part is more balanced, which reduces the occurrence of defects such as cracks and uneven wall thickness, which is beneficial to improve the sealing and mechanical properties of the heat shrink tube after expansion.
