-
Correct and reasonable die is the premise of aluminum alloy die casting production, and plays an important role in ensuring the quality of aluminum alloy die castings.
-
In the production of die-cast parts, gas holes, shrinkage cavities, and deformation are high-frequency defects. They not only affect the appearance but also weaken the product performance, so targeted prevention and handling plans must be formulated.
-
Quality control of die-cast parts runs through the entire production process. The three key links—mold design, die-casting technology, and post-processing—are closely interconnected, and deviations in any link may lead to product defects.

What are the Advantages and Disadvantages of Aluminum Alloy Die Casting Surface Treatment Processes?
Surface treatment processes for aluminum alloy die castings have their own focuses, each with limitations while improving performance. Understanding their advantages and disadvantages helps in precise selection based on specific scenarios. -
Aluminum alloy die castings have become an ideal choice that balances aesthetics and durability, thanks to their excellent compatibility with surface treatments. This characteristic stems both from the chemical activity of die-cast aluminum materials and their dense surface structure, enabling them to adapt to various treatment processes, while improving the appearance texture and significantly enhancing corrosion resistance.
