Sango Manufacturing Engineering FAQ
What makes Sango different from other manufacturing platforms or intermediaries?

Unlike conventional sourcing brokerages, Sango integrates factory-direct production facilities, in-house precision inspection labs (CMM, 2D optical, XRF), and automated digital workflows. We operate our own certified manufacturing cells alongside a tightly audited network of over 700 partner facilities under unified QC standards. This guarantees real DFM insights, direct factory pricing without broker markups, and end-to-end NPI support from prototype to mass production.
