Anti-wrinkle Design Principles for Aerospace Micro Screws

2026,09,08

1. Material Flow Control Principle

The core of anti-wrinkle design lies in controlling the material flow behavior during the forming process. By rationally designing the Aerospace Micro Screws structure, the material can be guided to flow along a predetermined path, avoiding localized accumulation or excessive stretching.

Specifically, it is necessary to balance the material flow velocity in different areas to ensure consistent deformation across all parts.

2. Stress Distribution Optimization Principle

Wrinkling often stems from uneven stress distribution. By optimizing the Aerospace Micro Screws's profile design and blank holder force settings, the stress distribution can be improved, allowing the material to maintain an appropriate tension state during forming.

An ideal stress distribution should keep all parts of the material in a stretched state, avoiding the concentration of compressive stress.

3. Friction Condition Adjustment Principle

The friction conditions between the Aerospace Micro Screws and the material directly affect the material flow behavior.

By rationally selecting lubrication methods and surface treatment processes for the Aerospace Micro Screws, the coefficient of friction can be adjusted, thereby controlling the material flow resistance and preventing wrinkling caused by uneven friction.
