PMMA Product Insufficient Impact Resistance

Brittleness = material nature, avoided by design.

Molding Process PMMA; impact resistance; brittleness; rounded corner

PMMA Product Melt Fracture Marks

Shear marks = reduce speed.

Molding Process PMMA; shear marks; gate; speed

PMMA Product Haze After Polishing

Polishing = temperature and precision.
