FAQ
Q: Can you ensure the perpendicularity (90-degree alignment) between the bottom flange and the side bore?
A: Yes. While investment casting offers excellent CT4-CT6 linear dimensions, we load the part into custom CNC fixtures for secondary machining. This guarantees that the bored hole and the bottom sealing face are perfectly perpendicular within micron tolerances.
Q: Do you accept specialized automotive quality standards like IATF 16949 documentation?
A: Yes. Our foundry has a wealth of experience supplying automotive and industrial OEM components. We can provide full PPAP (Production PartApproval Process) documentation, control plans, and FMEA reports upon your request.
Q: What sealing face roughness can you achieve on the bottom flange plate?
A: Our CNC face-milling centers can achieve a surface finish of Ra 1.6 to Ra 3.2 (or smoother based on blueprint specs), ensuring a flawless, leak-free flush mating fit with your rubber gaskets or O-rings.
