The casting process integrates advanced technologies including electromagnetic stirring, online degassing, dual-stage ceramic filtration, oil-gas casting, and online hydrogen monitoring. These measures effectively reduce impurity content, optimize microstructure, ensure smooth ingot surfaces, refine grains, and enhance ingot plasticity, resulting in uniform deformation during subsequent processing.
Advanced homogenization equipment with precise temperature control and well-designed homogenization procedures. Single-stage, two-stage, or multi-stage homogenization schedules are implemented according to the characteristics of different alloys, effectively eliminating intragranular and regional segregation, relieving casting stress, reducing deformation resistance, and improving machining performance. This ensures uniform microstructure, minimizes residual secondary grains, and provides durable cast billets for subsequent production.
Our manufacturing process for aluminum extrusion covers die development, billet heating, extrusion, quenching, stretching and straightening, cutting and aging. We provide feasibility assessment of profile design and production process according to resources provided by the customer, including 2D drawings, 3D models, alloy designation, cross-sectional dimensions and mechanical property requirements.
Our products include aluminum tubes, rods, angles, channels, I-beams and custom profiles with complex hollow design, multiple cavities and asymmetrical outline.
