Wrinkling in Aerospace Micro Screws and Its Impact

2026,09,08

Wrinkling is a common defect in sheet metal forming, particularly prominent in Aerospace Micro Screws manufacturing.

Wrinkling not only severely affects the appearance quality of the product but also reduces its mechanical properties and lifespan.

When a sheet metal is subjected to uneven compressive stress during stretching, the material becomes unstable and deforms into wavy or wrinkled shapes; this phenomenon is called wrinkling.

The impact of wrinkling on the product is mainly manifested in the following aspects: First, it produces obvious wrinkles, compromising the smoothness and gloss of the product surface.

Second, the material thickness changes in the wrinkled areas, leading to a reduction in local strength; third, severe wrinkling may prevent subsequent processes from proceeding normally and may even damage the mold.

Therefore, anti-wrinkling measures are a crucial aspect of ensuring product quality in Aerospace Micro Screws design.

Anti-wrinkling design for Aerospace Micro Screws is a comprehensive technology that requires systematic consideration of mold structure, process parameters, material properties, and other factors.

Through scientific design methods and advanced technologies, wrinkling defects can be effectively controlled, ensuring the product's appearance quality and mechanical properties.

With the development of numerical simulation and intelligent control technologies, anti-wrinkle design is moving towards greater precision and efficiency.

In practical applications, a suitable anti-wrinkle solution should be selected based on the specific product characteristics and material properties, and continuously optimized through trial molding verification to ultimately achieve high-quality stretch forming results.
