Jwell Sheet Extrusion Die Series for Single and Multilayer Products
Six sheet extrusion die configurations for PC, PS, PP, PE, PLA, PET, and PVC sheet, plate, film, and multilayer coextrusion.
JW-P-K1 — Fast-Opening Sheet Die
The JW-P-K1 features push-pull fine adjustment of the upper lip and a flexible lower lip for fast online thickness changes without stopping production. The maximum adjustment range is 5 mm. A 45-degree restrictor bar supports flow adjustment. This model is suitable for single- or multilayer PC, PS, PP, PE, and PLA sheet or plate.
Suitable Materials: PC, PS, PP, PE, PLA
Layer Structure: Single-layer or multilayer
Maximum Adjustment Range: 5 mm
Changeover Feature: Online thickness adjustment without stopping
JW-P-A1 — Standard Sheet and Plate Die
The JW-P-A1 uses a standard coat-hanger flow channel and a micro-adjustable upper lip. It is suitable for single- or multilayer PET, including APET and PETG, as well as PC, PS, PP, and PLA sheet or plate up to 2100 mm wide and from 0.14 to 2 mm thick.
Suitable Materials: PET (APET, PETG), PC, PS, PP, PLA
Layer Structure: Single-layer or multilayer
Maximum Product Width: 2100 mm
Product Thickness: 0.14–2 mm
JW-P-AT1 — Automatic-Adjustment Sheet Die
The JW-P-AT1 integrates an automatic control unit into the upper lip. Adjustment is divided into manual and automatic sections: the documented manual adjustment range is 1 mm, and the automatic adjustment range is 300 μm. It is suitable for PC, PS, PP, PE, and PLA single- or multilayer sheet or film in different widths.
Suitable Materials: PC, PS, PP, PE, PLA
Product Forms: Sheet or film
Layer Structure: Single-layer or multilayer
Manual Adjustment Range: 1 mm
Automatic Adjustment Range: 300 μm
JW-P-D1 — Multi-Manifold Coextrusion Die
The JW-P-D1 combines materials inside the die through multiple flow manifolds, supporting improved thickness distribution between layers. It uses a micro-adjustable upper lip, a fixed lower lip, and a 45-degree restrictor bar for the core layer. This model is intended for PC, PS, PP, PE, and PLA multilayer coextruded sheet.
Suitable Materials: PC, PS, PP, PE, PLA
Application: Multilayer coextruded sheet
Main Structure: Multi-manifold in-die combination
JW-P-C1 — General-Purpose Sheet Die
The JW-P-C1 has a standard coat-hanger flow channel, adjustable upper lip, exchangeable lower lip, and 45-degree restrictor bar. It is suitable for single- or multilayer PVC, PS, PP, PE, and PC sheet from 0.8 to 12 mm thick.
Suitable Materials: PVC, PS, PP, PE, PC
Layer Structure: Single-layer or multilayer
Product Thickness: 0.8–12 mm
JW-P-C2 — Pressure-Stabilized Sheet and Plate Die
The JW-P-C2 combines a gradual teardrop-shaped flat-shoulder flow channel with triangular diversion and stepped flow stabilization. This structure is designed to reduce die-lip deformation caused by high extrusion pressure. A manually push-out, fine-adjustable flexible upper lip supports precise setting, while a flat restrictor bar minimizes material stagnation and related degradation. The exchangeable lower lip can be selected with different openings for different thickness requirements. This model supports single- or multilayer PC, PS, PP, PE, PLA, and PVC sheet or plate.
Suitable Materials: PC, PS, PP, PE, PLA, PVC
Layer Structure: Single-layer or multilayer
Lower Lip: Exchangeable for different die openings
