FAQ
Q: Can we request custom thread pitches or a specific thread length for this flanged sleeve?
A: Yes, absolutely. We operate 100% as an OEM foundry. We can program our CNC tooling to chase custom thread metrics, BSPP, or NPSM pitches, and adjust the sleeve height precisely according to your project blueprints.
Q: Why choose an investment cast flanged sleeve instead of machining from a solid bar stock?
A: Machining a hollow flanged component from solid bar stock results in massive raw material waste and long machine center cycle times. Our silica sol investment casting creates near-net shapes directly from the tool mold, leaving minimal machine allowance and significantly lowering your bulk order costs.
Q: Is the raw casting dense enough to handle high-pressure fluid lines?
A: Yes, our silica sol investment casting produces an incredibly uniform, high-density metallic grain matrix with exceptional tensile strength. It completely avoids the micro-porosity issues commonly found in sand castings, making it fully reliable for leak-proof industrial and marine applications.
