Core Technology：

AFSD technology is a solid-state additive manufacturing technique based on the principle of stirring friction. Its core process involves generating heat through friction between a rotating tool head and metal raw material at temperatures below the material's melting point. This softens the material to a plastic state, enabling layer-by-layer deposition and compaction onto a substrate to form a “dense” three-dimensional structure. Compared to traditional fusion welding techniques, AFSD technology reduces carbon emissions by over 40%, meeting the requirements of green manufacturing.

Technical Advantages：

• More stable forming quality: Solid-State Additive Manufacturing reduces issues like porosity and cracks that may occur in traditional fusion welding, resulting in higher product performance.
• Better cost control: Continuous rod feeding technology allows equipment to load raw materials without shutdown, further improving production efficiency.
• Enhanced repair capability: AFSD technology enables component repair, minimizing the heat-affected zone during the process while extending the service life of critical parts.

Application Areas of AFSD Technology

Aerospace Applications：

• Satellite Adapter: Satellite adapters manufactured using AFSD technology feature enhanced strength and lightweight design, meeting spacecraft requirements for high-performance materials.
• Rocket Tank Bottom: A 3.35-meter diameter carrier rocket tank bottom is showcased on-site. This product achieves weight reduction and efficiency gains through AFSD technology, lowering production costs and cycle times.

  AFSD technology significantly enhances the quality and reliability of large structural components while reducing production costs and cycle times.

Maritime Applications：

• Hull Manufacturing: AFSD technology can be applied to construct hulls for large vessels, enhancing navigational efficiency and durability.
