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.

Recycling & Pelletizing Screws
To promote the circular economy, we developed a robust plasticizing unit specifically designed to handle Post-Consumer Recycled (PCR) materials. The reinforced venting design thoroughly eliminates moisture and bubbles, while the ultra-wear-resistant surface treatment effectively resists abrasion from metals and impurities. A special mixing section uniformly blends recycled materials with different flow coefficients, stabilizing the output melt pressure. This not only significantly increases the purity of recycled pellets but also ensures the highly efficient, continuous operation of the pelletizing line.
Food & Medical Grade Conveying Screws
In the food processing and pharmaceutical fields, we provide top-tier components that comply with strict international regulations such as the FDA. Manufactured entirely from medical-grade stainless steel, paired with non-toxic polishing and anti-stick surface treatments, we ensure that bacteria cannot breed. The dead-zone-free flow channel design supports rapid Clean-In-Place (CIP) procedures, guaranteeing absolute zero contamination between batches. It provides extremely stable quantitative conveying, offering the most reassuring hardware for industries requiring absolute cleanliness.
Industrial Feeding Screws
For powders, granules, and additives in heavy industries and chemical plants, we provide a highly efficient and stable quantitative conveying solution. The design specifically considers the material's angle of repose and flowability, thoroughly solving the bridging or leakage problems prone to occur in traditional hoppers. The sturdy shaft and wear-resistant flights handle even highly abrasive raw materials with ease. Customized length and pitch configurations ensure absolute precision and smoothness in front-end feeding for industrial production lines.
