The Advantages of PC Dual-color Co-extrusion Design

The dual-color co-extrusion process represents a significant manufacturing advancement. Instead of extruding a single-color tube and applying paint, two different colored PC materials are simultaneously extruded through a single die.

Key advantages:

• Cost reduction: 25-35% savings by eliminating painting steps
• Color permanence: Integral to material — no chipping or fading
• Environmental benefits: No VOC emissions from painting
• Production speed: Single-step process reduces lead time
• Design flexibility: Complex color transitions impossible with painting

Our lines can produce tubes with wall thickness ratios up to 70/30 between two colors, matching any Pantone or RAL reference.
