16-09-2025 PVC tube extrusion is a widely used manufacturing process in which raw PVC material is melted and forced through a mold to form continuous tubes of specific diameters and wall thicknesses. A critical step in this process is effective cooling, which ensures that the extruded tubes maintain their shape, dimensional accuracy, and surface quality. Improper or uneven cooling can lead to warping, deformation, or internal stresses, affecting the final product quality.
