FAQ

1. What are the advantages of aluminum castings over cast iron and stainless steel parts?
Core advantages include lightweight (density is only 1/2-1/3 of the two), corrosion resistance, easy processing, and excellent thermal/electrical conductivity. Suitable for weight reduction and low-corrosion scenarios, with slightly lower room-temperature strength.
2. How to choose between sand casting, die casting, and low-pressure casting?
Sand casting: Low cost, suitable for large parts; ideal for non-precision structural components.
Die casting: High precision, efficient for mass production; suitable for small precision parts.
Low-pressure casting: High density; suitable for load-bearing parts.
3. Are there requirements for the wall thickness of aluminum castings?
Minimum wall thickness: ≥1.5mm for die castings, ≥3mm for sand castings. Maximum thickness should not exceed 10mm. Wall thickness must be uniform to avoid cracking/shrinkage cavities.
4. Which surface treatment to choose?
Outdoor rust prevention: Electrophoresis.
Appearance parts: Anodizing (dyeable).
Low-cost indoor parts: Passivation.
Decorative needs: Powder/paint spraying.
5. How to quickly judge qualified quality?
No cracks, pores, or burrs on the surface.
Key dimensions meet drawing tolerances.
Request material certification from the manufacturer.
6. What is the service life?
5-15 years under normal use, affected by material quality, operating environment (humidity/high temperature), and load. High-quality materials + suitable surface treatment ensure longer durability.
7. What is needed for customization? What is the lead time?
Provide 2D/3D drawings, material/surface treatment requirements, and operating scenarios. Sample lead time: 7-20 days; mass production lead time: 10-30 days.
8. Is cracking or deformation a quality issue?
Cracking under little/no load, dimensional deviation beyond limits, or peeling surface treatment are quality issues. Overloading, improper environment, or incorrect installation are usage-related issues.
