Chalco 6061 aluminum slug production and processing
In our foundry, we ensure that every slug meets high quality standards by strictly controlling the production process. We melt high-quality aluminum and internal material residues, and do not use secondary scrap that may affect product quality. Here is our aluminum slug production process:
1. Melting and Alloying: We alloy and treat the aluminum melt to ensure the accuracy and uniformity of its composition, guaranteeing product quality. The treated melt is then prepared for rotary casting to form narrow strip alloys.
2. Casting and Hot Rolling: During the casting stage, we use precision rotary casting to create narrow strip alloys. These are then processed through hot rolling mills to adjust the thickness and are wound into hot-rolled coils, serving as input material for manufacturing billets.
3. Cold Rolling and Laser Measurement: The hot-rolled coils are further processed through cold rolling mills. During cold rolling, the thickness of the strip is precisely measured using laser measurement equipment to ensure it meets quality standards and tolerance requirements.
4. Precision sawing: The sawing process for slugs involves using high-efficiency sawing equipment to precisely cut aluminum rods into aluminum slug blanks that meet specified dimensions and tolerances, providing a high-quality foundation for subsequent processing.
5. Stamping and Annealing: We use efficient stamping lines with advanced stamping machines, achieving speeds of up to 300 strokes per minute. After stamping, the billets are sent to an annealing furnace to reach the appropriate hardness, ensuring mechanical properties and formability.
5. Surface Treatment: Stamped aluminum billets can undergo sandblasting or rolling treatments as per customer requirements to ensure surface quality. We use advanced sandblasting machines for more delicate surface treatment, enhancing the product's appearance and performance.
6. Packaging and Storage: After surface treatment, the aluminum billets are packaged and stored in sealed warehouses to ensure they remain free from contamination and damage during transportation.
In addition, our production process is flexible, and we can customize various alloys according to customer needs, and we are able to manufacture aluminum billets of different thicknesses and diameters. Whether it is standard alloys or special alloys jointly developed according to buyer needs, we can provide high-quality and high-precision aluminum billet products, which are widely used in the automotive, electronics, packaging and other industries.
Through this entire set of rigorous production processes, we are able to ensure the quality and consistency of aluminum billets, meeting our customers' high requirements for precision, performance and appearance.

Chalco 6061 aluminum slug quality control
In aluminum billet production, ensuring high quality and consistency is our top priority. Through a series of precise quality control measures, we can provide aluminum billet products that meet high standards, especially for the automotive, electronics and packaging industries.
1. Alloy consistency and metallurgical pollution control
- Alloy Composition Control: We strictly monitor the chemical composition of aluminum alloys to ensure the consistency of each batch of materials.
- Metallurgical contamination inspection: By comparing the expected and actual weights of aluminum billets, metallurgical contamination can be quickly identified to avoid potential defects and ensure product quality.
2. Dimension and weight accuracy
- Precise dimensional control: Use high-precision measuring tools (such as laser measuring instruments) to ensure that the diameter, thickness and other dimensional tolerances of the aluminum billet are within strict ranges.
- Weight grading: A precision grader is used to check the weight of each aluminum billet to eliminate any deviations and ensure that each aluminum billet meets the specifications.
3. Surface quality and defect detection
- Surface finish inspection: Through visual inspection and automated testing equipment, ensure that there are no scratches, cracks or other defects on the surface of the aluminum blank.
- Surface defect screening: Use a high-power magnifying glass or X-ray to check tiny defects on the surface of the aluminum blank to ensure appearance and functional requirements.
4. Heat treatment and mechanical properties testing
- Uniform heat treatment control: Ensure uniform temperature distribution during heat treatment of aluminum billets to optimize their hardness and ductility.
- Mechanical properties test: Tensile test and hardness test are used to ensure that the aluminum billet meets the required strength and toughness requirements, which is particularly suitable for high-demand automobile and electronic products.
5. Reduce waste and improve production efficiency
- Precision grading and process improvement: Reduce waste in production, improve production efficiency and optimize process flow through weight grading system.
- Energy and cost control: During the production process, accurate control of weight and material consumption reduces energy costs and waste generation, supporting sustainable production.
6. Automated and data-driven quality management
- Automated testing system: Use automated equipment to record data in real time, monitor deviations in the production process, and make timely adjustments to ensure stable quality.
- Data analysis support: Through statistical process control (SPC), we use real-time data analysis to optimize production and quality management and drive continuous improvement.
