Flat Die , Extrusion Sheet Die, Sheet T Die

This flat die, extrusion sheet die, and sheet T die is engineered for precise thickness control in thermoplastic film and sheet extrusion, with designs tailored for materials such as PP, PE, APET, PETG, PS, HIPS, ABS, PC, PMMA, PVC, and EVA. The die configuration varies based on application: restrictor bar-free designs suit thicknesses under 2mm, while dies with restrictor bars accommodate both thin and thick outputs, especially with degradable polymers. Sliding upper lips provide up to 12.5mm of travel for consistent width control in high-volume production, and the Tiande lip adjustment system is integrated where specified for dynamic gap tuning.

The dies are manufactured using hardened tool steel with surface treatments to resist wear and corrosion, ensuring dimensional stability over extended runs. Multi-manifold designs are standard for co-extrusion applications, allowing separate flow channels for cap layers and core materials, which reduces expensive resin usage by up to 30% compared to feedblock systems. Lip gap tolerances are held within ±0.02mm for consistent output, and internal channels are polished to a 0.4μm Ra finish to minimize melt drag and degradation. These features align with industry norms for high-precision extrusion tooling used in packaging and industrial film production.

These dies are purchased by manufacturers producing rigid and flexible packaging, signage, construction films, and pharmaceutical blister packs. Buyers typically require custom lip widths, material compatibility, and integration with existing extrusion lines. Trade terms are negotiated directly with the supplier; standard packaging includes wooden crates with internal foam cushioning. Lead times range from 4 to 8 weeks depending on complexity, and incoterms are typically FOB Ningbo or Shanghai. All dies are tested for flow uniformity before shipment, but buyers should request test reports prior to order confirmation.

Taizhou Huangyan Wanlian Extrusion Mould Co., Ltd. is a specialized manufacturer of extrusion dies based in Huangyan, Zhejiang, China. The company focuses exclusively on flat dies, sheet dies, T-dies, and related components such as melt pumps and hydraulic screen changers. Their production facility is equipped with modern CNC machining centers and has experience serving clients in packaging, construction, and industrial film sectors. The supplier does not list certifications, headcount, or annual output, but their focus on die design and tooling suggests a niche technical capability.

The supplier's profile indicates active engagement in R&D for die geometry and flow optimization, particularly for multi-layer co-extrusion. They do not claim export history, client names, or certifications such as ISO. Their response rate and average response time are not recorded on the listing, indicating limited automated buyer communication. Buyers should request samples or test reports before bulk orders. The company's strength lies in its ability to customize die geometries for specific materials and thickness requirements, not in broad marketing claims.
