SPC (Stone Plastic Composite) decking boards use high-calcium PVC as the base material, delivering waterproof, fire-resistant, dimensional stability, and high wear resistance. Widely applied in residential, commercial, and outdoor decking, high filler content places extreme demands on screw wear resistance and feeding capability. PIPPL high-filling conical twin screws with enlarged feed openings and thickened dual-alloy barrels (tungsten-carbide reinforced) are specifically engineered for stable, long-life SPC decking production.
Key Features
• Enlarged feed opening and optimized geometry prevent bridging of high-calcium powder.
• Thickened dual-alloy barrel with tungsten-carbide reinforcement for superior abrasion resistance.
• Reinforced mixing elements ensure uniform dispersion of calcium carbonate.
• Service life extended by 30% or more compared with standard designs under high-fill conditions.
• Stable high output suitable for continuous SPC decking lines.
Product Types
SPC flooring boards, outdoor decking boards, and waterproof composite panels in various thicknesses and surface textures.
