AI Technical Summary
Existing technologies make it difficult to efficiently manufacture double door rings with A-grade surfaces, and traditional manufacturing methods result in uneven material cooling, affecting production efficiency and quality.
The double door ring is formed by hot stamping technology. The surface of the mold is locally thinned by milling to increase the diameter of the cooling channel. High-strength steels such as HF-950-1300-MnB-S and HF-800-950-MnB-S are used to optimize mold cooling and ensure uniform material cooling, forming a Grade A surface.
It enables rapid prototyping of double door rings, with uniform material cooling, improving production efficiency and quality, and is suitable for exterior and structural components of consumer vehicles.
