6. Common Problems & Solutions in the Use of Aluminum Die‑Cast Parts
6.1 Surface Oxidation & Color Difference Problem
Problem: ADC12 alloy contains high silicon content, which is prone to surface graying, oxidation spots and color difference after long‑term use, and ordinary anodization is easy to produce defects.
Solution: Adopt special conductive oxidation and oil mist sealing process to form a uniform protective film on the surface of the parts, which can resist 96‑hour neutral salt spray test and effectively avoid oxidation and color difference.
6.2 Thin‑Wall Part Deformation Problem
Problem: Thin‑walled aluminium casting parts are prone to deformation and dimensional deviation during processing and assembly, affecting assembly accuracy.
Solution: Use five‑axis CNC one‑clamp integrated processing technology, control the cutting depth and feed rate in sections, avoid extrusion deformation, and ensure the dimensional stability of thin‑walled parts.
6.3 Tool Adhesion & Burr Residue
Problem: Aluminum alloy material is soft, and burrs are easy to remain during cutting, and tool adhesion often occurs, affecting surface smoothness.
Solution: Use aluminum‑specific anti‑stick coating tungsten steel tools, match with professional oil mist cooling technology, and complete fine deburring in one process to ensure smooth and burr‑free parts surface.
6.4 Low Assembly Matching Accuracy
Problem: The dimensional tolerance of ordinary die‑cast parts is unstable, resulting in poor assembly matching and gaps between parts.
Solution: Control the processing tolerance within ±0.005mm through precision finishing, and conduct full inspection of finished product size to ensure 100% assembly matching rate.
