Manufacturing Process Selection for Aluminum Billets

At Chalco, we utilize a variety of advanced manufacturing processes to ensure that our aluminum billet products meet the highest standards in quality, dimensions, and internal structure. Below are the key processes we use:

• Continuous Casting

  Chalco's continuous casting process involves continuously injecting molten aluminum into a water-cooled mold, achieving rapid and uniform solidification. The billets produced through this method have fine grains and consistent dimensions, making it ideal for high-volume production. It is especially suitable for industries like aerospace and automotive, where material uniformity and high precision are crucial.

• Direct Chill Casting

  In the direct chill casting process, molten aluminum is poured into preheated molds and rapidly cooled through water quenching or natural cooling. This process is simple and cost-effective, making it ideal for applications requiring high-quality microstructures with faster production speeds. It is widely used in industries like construction and consumer electronics, ensuring material purity while accommodating customization needs.

• Semi-Continuous Casting

  Chalco's semi-continuous casting process combines the benefits of both continuous casting and batch casting. By producing in segments, it offers enhanced dimensional control and uniformity in the internal structure. This method is particularly suited for producing large-diameter billets or billets made from special alloys, providing reliable quality for diverse industrial applications such as heavy-duty equipment and high-load structural parts.
