8. Technical FAQ: Professional Terminologies Explained
- Q1: What is the difference between Green Sand Metal Casting and Aluminum Die Casting?
- Green Sand Metal Casting uses silica sand as mold material for economical, flexible production, ideal for low-medium volumes and large flanges. Aluminum Die Casting employs reusable steel molds for high speed, tight tolerance, and surface finish (down to Ra 1.5 μm) — preferred for high-volume standardized parts.
- Q2: Which aluminium alloy offers best strength-to-weight for flanges?
- AlSi10Mg is widely favored due to its balance of strength (yield ≥170 MPa), ductility, and corrosion resistance. A380/ADC12 is suitable for complex die cast geometries due to very good castability.
- Q3: What does “Pressure Rating PN10–PN40” mean?
- PN stands for “Pressure Nominal”, denoting maximum working pressure at 20°C; PN16 = 16 bar. Flanges with higher PN accommodate higher system pressure.
- Q4: Which standards do aluminium flanges typically comply with?
- Main standards: ISO 9001, ISO 8062 (casting tolerances), ANSI/ASME B16.5 (flange dimensions), ASTM B26 (aluminium alloys), EN 1092-1 (European flange standard).
- Q5: How is corrosion resistance tested?
- Laboratory ASTM B117 salt-spray test exposes the sample for 1000h; pass criteria: no severe pitting/rust (>98% covered surface remains intact).
- Q6: What is “CNC Machining” in flange production?
- After casting, CNC Machining refers to computer-controlled turning/milling (e.g. for bolt holes, sealing faces) — enabling each flange to meet CT7-CT8 tolerance grades (ISO 8062).
- Q7: How does YD Castings ensure dimensional accuracy?
- Coordinate Measuring Machine (CMM) is used to check ±0.05 mm critical dimensions post-machining; every lot is visually and dimensionally tested, and data is recorded per batch.
