PVC Profile

PIPLL PVC Profile Extrusion Screw & Barrel | UPVC Window & Door Specialist
Product Overview
PIPLL is a global leader in high-performance PVC profile screw and barrel systems. PIPLL targets rigid PVC and UPVC extrusion challenges, optimizing structure, materials, and flow to solve pain points like uneven plasticization, surface streaks, bubbles, low output, and rapid wear.
Fully compatible with parallel and conical twin-screw extruders, PIPLL products support UPVC doors, windows, wall/ceiling panels, fittings, and decorative profiles. Leveraging exclusive low-shear, high-plasticization technology, PIPLL enables stable high-speed production, zero-defect surfaces, and long-term equipment reliability.

PIPLL Core Technical Advantages

1. PIPLL Low-Shear Gradient Plasticization
For heat-sensitive rigid PVC, PIPLL uses a gradient shear design. It delivers fast mixing in the feeding section and gentle plasticization in compression and metering, controlling shear heat to eliminate yellow lines, black spots, and melt streaks.

2. PIPLL Precise Compression Ratio
Tailored for profiles, PIPLL sets the compression ratio at 2.2:1–2.6:1. This ensures full melt compaction, no internal voids, stable dimensions, and enhanced hardness and flatness.

3. PIPLL High Wear & Corrosion Resistance
PIPLL screws and barrels feature 38CrMoAlA substrate with nickel-based alloy centrifugal casting, achieving HRC58-62 hardness. Wear resistance is 3-5 times that of ordinary nitrided screws, extending service life and cutting replacement costs.

4. PIPLL Efficient Venting & Stable Extrusion
PIPLL optimizes venting length and thread structure to remove moisture and volatiles, eliminating surface bubbles, pockmarks, and internal hollows for a 100% smooth profile surface.

5. PIPLL Energy-Saving & High-Yield
PIPLL's optimized thread profiles reduce flow resistance. PIPLL boosts capacity by 15%-25% and cuts unit energy consumption by 18%, elevating production line profitability.
