PMMA Product Surface Orange Peel

Orange peel = replication.

Molds & Tooling PMMA; orange peel; replication; mold temperature

PMMA Injection Cycle Too Long

Cycle = cooling efficiency.

Injection Molding PMMA; cycle; cooling; water channel

PMMA Product Insufficient Impact Resistance

Brittleness = material nature, avoided by design.

Molding Process PMMA; impact resistance; brittleness; rounded corner

PMMA Injection Multi-Cavity Imbalance

Multi-cavity = balance.

Injection Molding PMMA; multi-cavity; runner; cooling

PMMA Product Corner Chipping and Edge Breaking

Corner chipping = brittleness + sharp corners.

Molds & Tooling PMMA; corner chipping; sharp corner; ejection

PMMA Injection Sticking to Mold (Vacuum Adsorption)

Vacuum adsorption = solved by air intake.

Injection Molding PMMA; mold sticking; vacuum adsorption; ejection

PMMA Product Melt Fracture Marks

Shear marks = reduce speed.

Molding Process PMMA; shear marks; gate; speed
