Jwell PC/PMMA optical sheet extrusion line is designed for the production of high-quality optical sheets made from polycarbonate (PC) or polymethyl methacrylate (PMMA). These materials are known for their excellent optical clarity, impact resistance (PC), and UV resistance (PMMA). They are used in various applications, including automotive parts, lighting fixtures, display panels, and signage.
1. Raw Material Feeding System:
- Hoppers and Dryers: Raw PC or PMMA granules are fed into the extruder via hoppers. Before feeding, the granules are dried to remove any moisture content, which is crucial to prevent defects in the final product.
- Gravimetric or Volumetric Feeders: These ensure accurate and consistent feeding of raw materials into the extruder, maintaining the correct formulation and quality of the sheet.
2. Extruder:
- Single or Twin-Screw Extruder: The extruder melts and homogenizes the PC or PMMA granules. The screw design and precise temperature control across different zones ensure the material is properly melted and mixed.
- Temperature Control: Critical for preventing degradation of the material and ensuring a uniform melt, with precise control in each zone of the extruder.
3. Extrusion Die:
- Flat Sheet Die: The melted polymer is forced through a flat sheet die, which shapes the molten plastic into a thin, flat sheet. The die design is crucial for achieving uniform thickness and surface quality.
- Die Lip Adjustment: Allows fine-tuning of the die opening to control sheet thickness accurately.
4. Calendering System:
- Calender Rolls: The extruded sheet passes through a series of calender rolls (usually three), which precisely control the sheet's thickness, surface finish, and optical clarity. The rolls are temperature-controlled to ensure proper cooling and to avoid internal stresses.
- Embossing Rolls: For applications requiring textured surfaces, embossing rolls can be used to impart the desired texture to the sheet.
5. Cooling System:
- Cooling Rollers: After calendering, the sheet is further cooled using cooling rollers to stabilize the material and prevent warping or deformation.
- Air Cooling or Water Bath: Additional cooling methods can be employed depending on the thickness and specific requirements of the sheet.
6. Thickness Measurement and Control:
- Online Thickness Gauges: Non-contact measurement systems continuously monitor the sheet thickness and make real-time adjustments to the extrusion parameters to ensure uniform thickness throughout the production run.
7. Edge Trimming and Scrap Reclaim:
- Trimming Knives: Edges of the extruded sheet are trimmed to achieve the desired width and remove any irregularities.
- Reclaim System: Trimmed edges and any off-spec material can be recycled back into the extrusion process, reducing waste.
8. Winding and Cutting:
- Automatic Winders: The finished sheet is wound into rolls for easy handling and further processing. Tension control systems ensure the sheet is wound without wrinkles or deformation.
- Cutting Systems: For producing sheets of specific dimensions, cutting systems like guillotine cutters or slitting machines are used.
- High Optical Clarity: Both PC and PMMA offer excellent transparency, making them ideal for applications requiring clear, high-quality visuals.
- Durability: PC sheets offer high impact resistance, while PMMA sheets provide good weather and UV resistance.
- Customization: The extrusion process allows for the production of sheets in various thicknesses, widths, and surface finishes to meet specific application requirements.
- Consistency: Advanced control systems ensure uniform thickness and quality throughout the production process.
- Automotive Industry: Used for headlamp lenses, instrument panels, and other optical components.
- Lighting: Ideal for light diffusers, covers, and lenses in lighting fixtures due to their excellent light transmission properties.
- Displays and Signage: Widely used in display screens, advertising panels, and signage for their clarity and durability.
- Architectural Applications: Employed in skylights, glazing, and other architectural features where clarity and strength are essential.
