Eight Processes.
One Point of Contact.
Most projects need more than one process. A housing gets machined, the bracket gets stamped, the enclosure gets molded — and suddenly you're managing three suppliers on three timelines. Sango runs all of it in-house at our Shenzhen factory and through a vetted partner network across China, so your parts arrive together.
CNC MACHININGMilling, turning and 5-axis work down to ±0.001″ and walls as thin as 0.020″. Simple parts ship in a day.
SHEET METALLaser cutting, CNC bending, welding and stamping. Prototypes in three days, down to 0.008″ material.
3D PRINTINGSLA, HP MJF, SLS and SLM metal. ±0.008″ accuracy for functional prototypes and short production runs, next-day.
INJECTION MOLDINGPlastic, overmolding and insert molding. No minimum order, T1 samples in two weeks, bridge tooling when you need volume.
DIE CASTINGHigh-pressure casting in aluminium, zinc and magnesium for parts that need complex geometry and real structural strength.
VACUUM CASTINGSilicone tooling for 10–100 parts with production-grade colour and texture — the fastest route to a batch that looks and feels final.
SURFACE FINISHINGOver 30 finishes: Type II and Type III anodising, electropolishing, powder coating, bead blasting and plating.
ASSEMBLY & QCHardware insertion, sub-assembly, custom kitting, and Zeiss CMM dimensional reports with every shipment.
Made in China.
Delivered Where You Work.
Shenzhen sits inside the densest manufacturing supply chain in the world — which is why materials, tooling and finishing that take weeks to source elsewhere take days here. Sango turns that into parts on your bench in North America or Europe within 3 to 10 days, with export documentation and duties handled before your shipment leaves.

More Than Parts.
A Product That Ships.
Plenty of shops will machine what you send them. Fewer will tell you the draft angle is wrong, the material is over-specified, or the packaging will fail a drop test. Sango supports the whole path from sketch to retail-ready box.
Project Initiation & Design
From concept to a design that can actually be made.
Industrial Design

Concept sketches, high-quality product renders, and appearance specification documents.

Mechanical Design

Detailed 2D/3D structural drawings built around manufacturing feasibility.

CMF Design

Colour, material and finish choices that align aesthetics with durability.

Cost Estimation

Design-stage cost forecasting and plans to bring unit costs down before tooling.

Every Part Measured.
Every Batch Documented.
Our quality team inspects at three points — before production starts, during the run, and before anything is packed. That's how we hold a 99.2% first-pass yield instead of finding problems after your parts have already crossed an ocean.

CMMs, 2D measuring systems, XRF analysers, gauges, micrometers and calipers — more than 20 tool types checking dimensions, material and finish.

Sango machined our robotic arm fixtures in 6061-T6 down to ±0.001″. Delivered in 4 days with complete Zeiss CMM inspection reports. Flawless fit.

David MillerSenior Robotics Engineer
Their engineering team caught a critical draft angle issue during initial DFM review, saving us thousands in tooling rework. T1 samples were spot on.
Sarah
Sarah LinMedical Device Lead
Best on-demand CNC partner we've used in Shenzhen. English-speaking project managers, transparent timelines, and parts always arrive in spec.
Marc
Marc KellerAerospace Hardware Tech
We transitioned bridge tooling to full production injection molding with Sango. Fast cycle times, zero MOQ issues, and flawless part consistency.
Alex
Alex TurnerIndustrial Automation VP
Rapid 3-day turnaround on precision laser-cut & bent sheet metal enclosures. Their DFM suggestions made assembly much faster on our production line.
Elena
Elena RostovaCleanTech Hardware Director
We manufacture precision medical diagnostics equipment and switched to Sango for our multi-axis CNC milling and silicone overmolding. Over the last 18 months, they have delivered more than 45,000 components across 30 production batches. What sets them apart is their engineering communication: every CAD upload gets a thorough DFM report within hours, highlighting potential tolerance stack-ups and tool clearance risks. Their quality documentation (Zeiss CMM inspection, material certs, RoHS compliance) is immaculate and passes our FDA audit requirements without hitch. Lead times are consistent and dependable.

What Engineers Say After the First Order
How do I confirm my design can be manufactured reliably?

Every successful production starts with a solid manufacturability review. Once you upload your 3D CAD file, our platform analyzes geometry, wall thickness, undercut features, and tolerance feasibility with instant DFM feedback. For complex or tight-tolerance parts, our senior manufacturing engineers perform a comprehensive manual DFM review within 24 hours, providing actionable recommendations to optimize cost, lead time, and production yield.
