How Are UPVC Windows Made? A Complete Manufacturing Process Guide

UPVC (Unplasticized Polyvinyl Chloride) windows have become a popular choice for modern homes due to their durability, energy efficiency, and low maintenance. But how are UPVC windows made ? In this article, we’ll explore the step-by-step manufacturing process of UPVC windows and doors, ensuring you understand the craftsmanship behind these high-performance products. Raw Materials Used in UPVC Manufacturing The primary material used in UPVC production is polyvinyl chloride (PVC) resin , combined with stabilizers, modifiers, and pigments to enhance strength, weather resistance, and color. Unlike regular PVC, UPVC does not contain plasticizers, making it rigid and ideal for window frames. Key Ingredients: PVC Resin – The base material Calcium Carbonate – Adds rigidity Titanium Dioxide – Provides UV resistance Impact Modifiers – Improves durability Lubricants – Ensures smooth extrusion Step-by-Step Manufacturing Process of UPVC Window...
