SJ-80 Optical Clear Sheet Extrusion Line with 150-250 kg/h Output Capacity, Class 10000 Dust-Free Enclosure, and Mirror-Finish Calender Rolls for PMMA and PC Sheets
The SJ-80 Optical is a specialized extrusion line for producing optical-grade PC and PMMA clear sheets used in LED lighting diffuser panels, display screens, and transparent protective covers. With precision gear melt pump, mirror-finish calender rolls, and Class 10000 dust-free enclosure, it delivers 150-250 kg/h of defect-free optical sheet with superior light transmission and clarity.
- Precision Gear Melt Pump: Positive displacement melt pump eliminates pressure pulsation, ensuring uniform sheet thickness with deviation below +/-0.02mm for optical applications
- Mirror-Finish Calender Rolls: Ultra-polished chrome-plated rolls with surface roughness Ra less than 0.01 micron, producing optically clear sheet without flow marks or surface defects
- Class 10000 Dust-Free Enclosure: Fully enclosed production zone from die to winder maintains cleanroom conditions, preventing dust and particle contamination critical for optical sheet quality
- Special Screw Coating: Bimetallic screw with wear-resistant coating prevents metal contamination and ensures material purity for transparent optical applications
- Precision Temperature Control: Multi-zone PID temperature control with +/-1°C accuracy throughout barrel, die, and calender for consistent optical properties
- Static Elimination System: Integrated ionizing bars neutralize static charge, preventing dust attraction during sheet handling and winding
