Frequently Asked Questions: Sourcing & TIG Manufacturing

Technical solutions addressing supplier qualification, structural joint integrity, dimensional repeatability, and intellectual property defense.

How does Sunmy control thermal distortion during thin-wall aluminum TIG welding?
We deploy dynamic custom copper backing chill blocks combined with pulsed AC TIG modulation. By controlling the peak vs. background current balance, we minimize total heat input into the parent material, restricting distortion within 0.1 mm prior to final CNC surfacing.
What non-destructive testing (NDT) capabilities are performed in-house?
Our quality control regimen includes liquid penetrant inspection (DPI), helium mass spectrometer vacuum leak testing for hermetic sensor and manifold components (down to 1x10^-9 mbar·l/s), hydrostatic pressure tests, and coordinated X-ray radiography with certified test partners.
Can you support multi-process production (CNC milling + stamping + welded sub-assemblies)?
Yes. Sunmy Hardware operates an integrated manufacturing structure where CNC milling, Swiss turning, sheet stamping, and precision GTAW welding happen under unified engineering management. We supply finished, surface-treated (anodized/passivated), and pre-assembled systems ready for final production lines.
How are customer designs and intellectual property safeguarded against third-party exposure?
Sunmy signs a legally enforceable bilateral Non-Disclosure Agreement (NDA) before accepting 2D/3D CAD data. Drawings are hosted on encrypted on-premise servers and shared strictly with cleared machine programmers on a need-to-know basis, ensuring complete exclusion from external brokerage channels.
What lead times are standard for rapid prototypes versus production batches?
Standard prototype runs with DFM analysis ship within 5 to 7 business days via air priority (DHL/FedEx). Scaled production batches typical of 500 to 50,000 units are completed in 3 to 4 weeks depending on surface treatment requirements and raw alloy extrusion availability.
