Precision Assembly
Engineering with SangoAt Sango, we bring precision machined and molded components together into finished assemblies without handing your project off to a third party. Our technicians work from your assembly drawings and BOM, verifying fit and fastener torque at every stage, so tolerances established in machining and molding aren't lost during build.Our capability covers mechanical fastening, adhesive bonding, press fits, and wire harnessing, along with structural steel, sheet metal, and molded plastic parts. This includes heat treated and glass filled materials that demand controlled handling to avoid marring or stress cracking finished surfaces.Sango's commitment to precision is backed by functional and dimensional testing on every completed unit, plus documentation you can trace back to the individual component batch. This combination lets us deliver finished assemblies that meet the rigorous demands of automotive, aerospace, and precision equipment programs.

Sango Assembly FAQ
Do I need to supply a BOM and assembly drawing, or can Sango help create one?

A bill of materials and assembly drawing speed up quoting and reduce fit issues, but if you only have individual part files, our engineers can help build the BOM and sequence from your design intent during the design review stage.

Is there a minimum order quantity for assembly work?
Can Sango source fasteners, inserts, and off the shelf components for my assembly?
What quality checks happen during and after assembly?
Can you handle mixed material assemblies, like metal parts with plastic housings?
What happens if an assembled unit fails inspection or doesn't meet spec?
Can you package and label finished assemblies for direct shipment to my customer?
Do you provide documentation for regulated industries like aerospace or medical?
