Blown Film Die Head Systems
Marking a strategic expansion, Ding Feng now offers advanced Blown Film Die Heads ranging from 3-layer IBC systems to 9-layer co-extrusion models. Every spiral mandrel channel is calculated via Computational Fluid Dynamics (CFD) to ensure absolute uniformity in layer distribution. We maximize bubble stability and optical properties, addressing critical needs for high-barrier packaging films (EVOH/PA). This integration helps clients achieve higher throughput and material savings.
Multi-layer Die Head
Design & Structure: Features precision-engineered flow channels, available in Spiral Type and Stack Type designs to ensure zero stagnation or material accumulation.
Functional Expansion: Supports complex co-extrusion of 11 layers or more. It allows for the addition of functional resins such as waterproof barriers, anti-UV agents, stabilizers, or recycled materials.
Technical Specifications: Engineered with high precision in roundness, concentricity, and verticality. Equipped with advanced Internal & External Cooling systems.
Two-color / Multi-color / ABA Die Head
Core Advantage: Optimized for rapid material and color changeover efficiency, significantly reducing raw material waste.
Economic Efficiency: The specialized flow channel design minimizes masterbatch consumption, making it ideal for production lines requiring frequent specification changes.
IBC - Internal Bubble Cooling Die Head
Primary Function: Features an integrated internal cooling control system. Targeted at high-output requirements, it works in tandem with high-efficiency air rings to substantially increase total production capacity.
ABC Three-layer Die Head
Application Scenario: Specifically designed for the co-extrusion of multiple resins, ensuring stable flow and consistent layering of different formulas at the point of convergence.
Double & Single-layer Die Head
Double-layer Die Head: Focuses on rapid color transitions and cost reduction in masterbatch usage.
Single-layer Die Head: The most widely adopted and cost-effective solution in the market, compatible with LDPE, HDPE, and PP resins.
