PMMA Sheet Extrusion Line

This line employs an extrusion system designed for optical-grade materials, operating in a strictly controlled clean environment from feeding to finishing to prevent contamination from black spots and impurities. Our unique screw design and T-die flow channel analysis ensure melt uniformity, effectively eliminating common flow marks and internal stress. Paired with a precision multi-roll calender and an online annealing oven (stress-relief unit), the PMMA sheets produced achieve a light transmittance of over 92% with excellent thickness tolerance and surface flatness.
