Precision Extrusion Die

Our coextrusion and polymer extrusion dies are engineered for high-precision applications and roll-to-roll processes, ensuring uniform polymer flow and consistent coating thickness across industries like packaging, automotive, and renewable energy. Designed for cast film, web coating, and laminating processes, these dies support complex multi-layer structures with exceptional repeatability. Leveraging advanced materials and proprietary machining techniques, our dies minimize defects, reduce waste, and enhance production efficiency.

Technical Specifications

• Materials: High-grade stainless steel or specialized alloys for corrosion resistance and durability in high-temperature polymer processing (up to 400°C).

• Tolerances: Our dies use advanced polymer extrusion techniques to achieve +0.001mm tolerances. Precision machining to ±0.001 mm for slot width and die lip uniformity, ensuring consistent flow distribution.

• Layer Configurations: Supports 2-7 layer coextrusion for applications requiring barrier films or multi-material laminates.

• Flow Optimization: Computational Fluid Dynamics (CFD)-designed internal channels to minimize shear stress and ensure uniform polymer distribution.

• Coating Widths: Customizable from 100 mm to 3,000 mm, adaptable for roll-to-roll and web coating systems.

• Surface Finish: Polished die lips (Ra < 0.1 µm) to reduce streaking and improve coating quality.

• Temperature Control: Integrated heating zones with ±1°C accuracy for consistent viscosity in polymers like PET, PP, and PE.

• Customization Options: Adjustable lip designs and modular feed blocks for rapid material changes or process adaptability.

Applications and Benefits
