Parameter
1. Advanced Casting Technologies
We employ multiple casting processes to suit your design complexity and volume requirements:
| Process | Best For | Key Benefits |
|---|---|---|
| Investment Casting | Complex geometries, thin walls, intricate internal passages | Near-net shape, CT6-7 tolerances, Ra 1.6-6.3μm surface finish |
| Sand Casting | Large pump bodies, heavy-wall designs | Cost-effective for larger sizes, up to 500kg single piece |
| Precision Sand Casting | Medium complexity, mid-to-large sizes | Good dimensional accuracy, economical for medium volumes |
2. Material Selection Guide
| Grade | Equivalent | Corrosion Resistance | Typical Applications |
|---|---|---|---|
| CF8 | AISI 304 | Good – general purpose | Clean water, light chemicals, HVAC |
| CF8M | AISI 316 | Excellent – chloride resistance | Chemical processing, marine, wastewater |
| CF3M | AISI 316L | Excellent – weldable | Food & beverage, pharmaceutical, high-purity |
| Duplex 2205 | UNS S32205 | Superior – pitting/crevice | Seawater, offshore, sour gas |
| 17-4PH | AISI 630 | Very good – high strength | High-pressure pumps, wear applications |
