Introduction
Choosing the right investment casting foundry is critical for pump and valve manufacturers.
1. Process Capability
Silica sol investment casting offers higher dimensional accuracy (CT4-CT6), better surface finish (Ra 3.2-6.3 μm), ideal for stainless steel and complex geometries.
2. Material Expertise
Ensure your foundry has expertise in: Stainless Steels (304, 316, CF8, CF8M), Duplex Stainless Steels (2205, 2507), Carbon Steels (WCB, WCC), Alloy Steels (WC6, WC9).
3. Quality Control
Look for IATF 16949, ISO 9001 certifications. Ask about raw material traceability, in-process inspection, NDT testing, CMM inspection, and MTR reports.
4. Dimensional Accuracy
Ask for: dimensional tolerance capability (CT4-CT6), surface finish capability (Ra 3.2-6.3), sample inspection reports.
5. Production Capacity
Consider prototype capability, production volume, lead time, scalability. Typical lead times: tooling 4-6 weeks, production 3-5 weeks.
6. Technical Support
Look for DFM review, engineering support, material selection guidance, problem-solving, and responsive communication.
7. Cost Considerations
Consider total cost of ownership: tooling, piece price, machining, quality, inventory, logistics. Better quality can result in lower total cost.
