Wall thickness and draft angles are two of the most critical design considerations for injection molded parts. Getting them right prevents defects and ensures consistent quality.
Wall Thickness Guidelines
Maintain uniform wall thickness throughout the part. Typical wall thickness ranges from 1.0mm to 4.0mm. Avoid sudden thickness transitions.
Draft Angle Requirements
Apply a minimum draft angle of 0.5 degrees for most materials, with 1-2 degrees recommended for textured surfaces.
