It refers to the surface of the part that can be peeled off layer by layer.

Causes:
(1) Mixing other incompatible polymers
(2) Excessive release agent used during molding
(3) resin temperature is inconsistent
(4) Excessive moisture
(5) The gate and the flow path have sharp angles
Remedies:
Material: Avoid incompatible impurities or contaminated recycled materials mixed into the raw materials
Mold design: Chamfer all runners or gates with sharp angles
Process:
(1) Increase the barrel and mold temperature
(2) Appropriate drying of the material before injection molding
(3) Avoid using too many release agent
