Core Process

Manufactured using shear spinning (thinning spinning) and power spinning (flow forming), this component addresses the challenges of forming complex curved geometries.

The process enables seamless or near-seamless integrated forming, significantly reducing or eliminating welding requirements while improving structural integrity and consistency.

Precision Control

Dimensional accuracy is controlled in strict accordance with:

GB/T 1804-m for linear tolerances

GB/T 1184-K for geometric tolerances

All critical mating surfaces undergo 100% inspection, with dimensional variation maintained within ±0.1mm to ensure precise assembly fit and performance reliability.

Surface Treatment

A mirror-grade deburring and surface finishing process is applied to achieve a smooth, defect-free surface.

Internal cavities are completely free of metal chips and residues

External surfaces exhibit a mirror-like finish with no visible tool marks

This level of surface quality is critical for preventing electric field concentration in sensitive applications.

Material Adaptability

Specialized in 5A02-H112 aluminum-magnesium alloy spinning, offering excellent corrosion resistance and structural stability.

The material and process combination ensures long-term durability and reliable performance under harsh outdoor environmental conditions.
