Precision Mechanical
Assembly with SangoAt Sango, we bring machined, sheet metal, and molded components together into finished assemblies. Our technicians install PEM self-clinching nuts, studs, and standoffs with Haeger insertion presses, drive blind and solid rivets, and apply structural and gasketing adhesives to bond dissimilar materials without adding weight or heat distortion.Beyond mechanical fastening, we route and terminate wire harnesses, integrate sub-assemblies, and kit hardware for final product builds. Every assembly step is documented against the customer's bill of materials, and every fastener torque and adhesive cure cycle is logged for traceability.Sango's commitment to precision and quality is backed by 100% functional testing before shipment and our ISO 9001:2015-certified quality system. This combination makes us a reliable partner for turnkey assemblies that meet the rigorous demands of any industry.

Design OverviewFirst, we take a close look at your design. This helps us spot any potential issues early on and ensures we have a clear plan before moving to the next stage, making the parts manufacturing and assembly smoother and more efficient.
Part PreparationBefore coming together, every part is cleaned and inspected. By removing rough spots and verifying fit, we set the groundwork for a seamless assembly.
AssemblyOur skilled team assembles each component with precision. Using the best tools and part assembly process, we ensure all metal and plastic parts align correctly and function as intended.
Packaging & DeliveryOnce complete, we pack your product with care, prioritizing its safety. We aim for prompt deliveries, getting your assembled item to you on schedule and in pristine condition.

Assembly ProcessesFrom CAD review to final functional test, each assembly stage is
tracked and signed off before moving to the next.

Manual AssemblyOur skilled hands piece together components accurately. Ideal for projects needing a personal touch or detailed craftsmanship.

Molding AssemblyWe use molding techniques to integrate parts, either by adding an outer layer (overmolding) or embedding components (insert molding) for robust integration.

PEM Fastener InsertionAutomated Haeger presses install self-clinching nuts, studs, and standoffs with consistent pull-out strength.

Riveting & Adhesive BondingBlind and solid rivets plus structural adhesives join panels and housings without heat distortion.
Assembly Methods
for PartsFrom hand-fit sub-assemblies to fastener-driven production runs, we match the method to the part's tolerance and volume requirements.
