Raw Material Assurance & Preprocessing

Aluminum Billet Warehousing System

30,000 Tons Annual Warehousing Capacity · Full-Spec Compatibility + Constant Temperature Protection

Warehousing & Production Capacity

Boasting an annual production capacity of 30,000 tons of standardized aluminum billets, our warehouse simultaneously stocks multi-specification billets with diameters of 90-150mm and lengths of 3-6m. Supporting a full range of alloy grades including 6063/6061/6005A/7075, we fully meet the OEM requirements of construction, industrial manufacturing, high-end manufacturing, and other scenarios.

Constant Temperature Protection

Adopting a closed constant temperature warehouse design with temperature controlled at 15-25℃ and humidity ≤60%, it avoids aluminum billet oxidation and moisture absorption from the source, ensuring the stability of the extrusion process.

Full Inspection Process Zone for Incoming Raw Materials

Zero-Error Raw Material Testing | 100% Unqualified Product Rejection

Inspection Process & Traceable Reports

With a sampling ratio of ≥5% for aluminum billets per batch, inspection items include alloy purity, surface defects, and tensile strength. Unqualified raw materials are directly rejected, ensuring a 100% acceptance rate for incoming materials. An electronic inspection report is generated for each batch, enabling OEM customers to access raw material data synchronously.

Testing Equipment

Equipped with high-precision optical emission spectrometers (alloy composition error ≤0.01%), Brinell hardness testers, and mechanical property testing machines, it covers comprehensive "composition - hardness - strength" testing across all dimensions.

Aluminum Billet Homogenization + Surface Preprocessing

Homogenization Process · Raising Profile Yield Rate to 98%

Homogenizing Annealing

Equipped with a 12-meter continuous homogenizing furnace (temperature control precision ±2℃), the process involves holding aluminum billets at 480-520℃ for 6-8 hours. This eliminates internal stress, refines grain structure, and increases the uniformity of the profile’s microstructure by 90%.

After homogenization, the profile yield rate increases from the industry average of 92% to 98%, and the adhesion of subsequent surface treatments is enhanced by 30%.

Surface Preprocessing

Adopting automatic shot blasting + chemical derusting technology, it removes oxide layers and oil stains from the aluminum billet surface, reducing extrusion defects such as scratches and bubbles.
