Jwell EVA/POE Plastic Film Mold Series
A 3050 mm photovoltaic film die engineered for low-temperature, high-pressure EVA and POE encapsulant extrusion.
Key Selling Points
- Material-Specific Cavity: Customized around the customer’s EVA or POE raw material.
- Flow Uniformity: V-manifold, triangular splitting, and steady-flow structures reduce M/W melt-flow patterns.
- Automatic Gauge Control: Thickness-gauge feedback supports real-time transverse fine adjustment.
- Multilayer Flexibility: Replaceable distribution mandrels enable different co-extruded layer structures.
- Durable Surface: 2738 die steel with 0.03-0.05 mm hard-chromium plating.
Applications / Material Options
- EVA and POE photovoltaic encapsulant films
- Low-temperature, high-pressure solar film extrusion
- Multilayer co-extruded encapsulant structures using a composite feedblock
Product Description
The JWELL EVA POE film die is designed for the extrusion of photovoltaic encapsulant film using EVA or POE materials. The 3050 mm die is built from 2738 die steel and uses a hard-chromium-plated surface with a stated chromium layer thickness of 0.03-0.05 mm. Its cavity can be customized around the raw material supplied by the customer, supporting procurement decisions based on the intended resin and film structure.
An extended V-shaped manifold, triangular flow-splitting design, and dedicated flow-stabilizing structure are used to reduce M-shaped or W-shaped melt-flow variation during extrusion. The die can be equipped with an automatic adjustment system: expansion bolts are micro-adjusted in real time using feedback from a traversing thickness gauge, helping operators correct transverse film accuracy during production.
For multilayer requirements, a composite co-extrusion feedblock supports multilayer processing. Different layer arrangements can be selected by replacing the distribution mandrel, allowing the die configuration to follow the required film structure. The source also states that the photovoltaic die head is intended to address crosslinking, decomposition, and curing behavior encountered when extruding low-temperature, high-pressure solar encapsulant materials.
This die series is therefore suited to manufacturers evaluating a dedicated EVA or POE photovoltaic film configuration, automatic gauge-control integration, and flexible multilayer architecture. Final cavity design, layer structure, and production settings should be confirmed against the customer’s actual resin formulation and line requirements before order placement.
