Tailored to address core plastic foaming challenges, PIPLL's foaming-specific barrel targets pain points like temperature sensitivity, strict pressure demands, poor foaming agent dispersion, and density fluctuations. By integrating high-precision zoned temperature control, an optimized compression ratio, and a dedicated mixing system, it effectively resolves issues such as uneven foaming, unstable density, and premature foaming agent decomposition, significantly enhancing product consistency and production efficiency.
Core Technical Highlights
PIPLL delivers comprehensive, foaming-focused optimizations:
1.PIPLL Ultra-Precise Temperature Control
Equipped with an independent multi-zone system boasting ±0.5℃ precision and spiral cooling channels for uniform heating and rapid response, it ensures foaming agents decompose evenly within the optimal range, eliminating uneven foaming and density fluctuations at the source.
2.PIPLL Foaming-Optimized Structure
Featuring a gradient low-compression ratio and a "shallow-deep-shallow" flight profile, it stabilizes melt conveying and maintains constant pressure. This prevents premature foaming agent decomposition and ensures uniform foaming inside the mold.
3.PIPLL High-Efficiency Mixing System
With patented barrier elements and multi-stage pin mixing, it delivers nano-level dispersion of foaming agents through repeated "shearing-dividing-reconverging" actions, eliminating large pores and local over-foaming for a fine, uniform cellular structure.
4.PIPLL Multi-Stage Venting
2-3 precisely positioned large-volume vents rapidly expel moisture, air, and volatiles, preventing gas contamination to avoid pinholes, bubbles, and rough surfaces, while improving surface finish.
5.PIPLL Tiered Wear & Corrosion Resistance
· Standard: 38CrMoAlA nitrided steel (HV900-1100) for ordinary PVC/PE/PP foaming.
· Wear-Resistant: Bimetallic alloy for high-fill WPC foaming.
· Corrosion-Resistant: Stainless steel lining/coating for corrosive foaming agents.
6.PIPLL High-Pressure Leak-Proof Design
A multi-seal structure withstands 40MPa pressure, preventing melt and gas leakage to ensure safe, uninterrupted 24/7 high-load operation.
Key Applications
PIPLL foaming barrels power diverse thermoplastic foaming extrusion:
1.PVC Foamed Products (Core Application)
Sheets (skinned/free-foamed/co-extruded), profiles (doors/windows, trims, baseboards), pipes, advertising boards, and furniture boards.
2.XPS Boards
Precise temperature control ensures uniform decomposition of CO₂/freon agents, delivering XPS boards with even density, fine cells, and top thermal insulation.
3.WPC Foamed Composites
Ideal for high-fill processes, producing lightweight, strong, waterproof WPC flooring, boardwalks, and outdoor furniture.
4.PE/PP Foamed Products
For PE sheets, PP profiles, and EVA products with excellent elasticity and cushioning.
5.Customized Foaming Solutions
Tailored barrels for PS, ABS, TPU, and other foaming materials.
