PVC Window Profile Extrusion Line Upgrade — Turkey

Building Materials — Turkey — Project using Conical Twin Screw Barrel

The Challenge

A leading Turkish PVC window profile manufacturer experienced frequent screw barrel wear due to high calcium carbonate filler content (40%+), requiring replacement every 8 months. Production downtime and replacement costs significantly impacted profitability.

Our Solution

Nanhaiya supplied bimetallic conical twin screw barrels (Φ65/Φ132) with enhanced wear-resistant lining specifically designed for high-filler PVC compounds. The barrel bore was precision-honed to ensure optimal fit with existing equipment.

Results Achieved

Screw barrel service life extended from 8 months to over 2.5 years. Annual replacement cost reduced by 65%. Production output increased 12% due to optimized screw geometry.
