Surface roughness in PVC pipe manufacturing is a common extrusion defect that affects product appearance, dimensional quality, and customer acceptance. This guide explains the major causes of rough pipe surfaces in twin extruder processing and practical solutions to achieve smooth, high-quality PVC pipe production.
High rejection rates in PVC pipe manufacturing increase production cost, waste raw material, and reduce profitability. This guide explains the most common causes of pipe rejection and practical process optimization methods to improve product consistency and reduce manufacturing defects.
Incorrect barrel temperature settings in a twin extruder can cause torque fluctuation, poor melt quality, surface defects, and dimensional instability. This guide explains the ideal temperature profile for PVC processing and how to optimize each barrel zone for stable production.
