Frequently Asked Questions (FAQ)

Q1: What types of aluminum alloy grades are available for die casting?

We primarily work with high-quality grades including ADC12 (ideal for excellent fluidity and castability in automotive parts/housings), A380 (offers high strength and heat resistance), A360 (optimized for superior corrosion resistance), and AlSi9Cu3(Fe).

Q2: What dimensional tolerance standards can be achieved?

Our standard components achieve a dimensional tolerance of ±0.1mm per 25mm. For high-tolerance precision parts, we can consistently achieve a precision of ±0.05mm per 25mm.

Q3: What surface finishing options do you support?

We offer a comprehensive range of finishing processes including Anodizing (5-25μm thickness), Powder Coating, Chromate Conversion, E-coating, Painting, and Polishing. The standard surface finish ranges from Ra 1.6-3.2μm as-cast and can be improved to Ra 0.8μm through precise machining.

Q4: How is the quality of die-cast parts verified?

Quality is monitored strictly under ASTM B85, DIN EN 1706, and JIS H 5302 standards. We use X-ray inspections to ensure porosity remains under 3% by volume, Coordinate Measuring Machines (CMM) for dimensional verification, and salt spray testing for corrosion resistance.

Q5: What is the minimum wall thickness capability for your parts?

A minimum wall thickness of 1.5mm is recommended to maintain the structural integrity of the casting. In general, our design parameters allow for typical thin-wall profiles within a 1.5mm to 5.0mm range.

Q6: What business capabilities and materials do you support beyond aluminum?

In addition to aluminum alloys, our material capabilities extend to Zinc alloys (ZAMAK3, ZAMAK5, etc.), Brass alloys (Si9Cu3, Cuzn-37, etc.), and Iron parts (Nodular Iron, Ductile Iron, etc.) using processes like sand casting, gravity casting, and stamping.
