How one-roof design-to-production beats fragmented outsourcing for robotics, hardware and industrial teams — speed, accountability and tolerances to ±0.05 mm.
📌 Key takeaways
- Jinghui 3D is a Shenzhen source factory doing design, 3D printing, CNC, vacuum casting and finishing all under one roof — no outsourcing.
- First articles in 24–72 hours; tolerances to ±0.1 mm (SLA) and ±0.05 mm (CNC).
- One dedicated engineer per order, itemized quote in 24 hours, DDP shipping to 30+ countries.
- Trusted by humanoid-robot leaders Unitree and UBTECH.
When a hardware or robotics team needs a prototype fast, the clock doesn't start when the printer warms up. It starts the moment a CAD file leaves your inbox — and then it waits. It waits at the SLA shop. It waits at the CNC shop. It waits at the painting shop. Every hand-off is a queue, and every queue is a risk to both your timeline and your tolerance.
What is vertically integrated prototyping?
Vertically integrated prototyping means every step of making a part — design, 3D printing, CNC machining, vacuum casting and finishing — happens inside a single factory rather than across several vendors. At Jinghui 3D, a Shenzhen source factory, the entire path from idea to inspection-ready part stays under one roof: design, 3D printing, CNC machining, vacuum casting, mold making and post-processing (painting, electroplating and assembly). Nothing is subcontracted. One plant, one team, one accountable point of contact.
The in-house process chain
- SLA / SLS / FDM — resin, nylon and engineering-plastic prints for functional and appearance parts.
- CNC machining — aluminum, steel and engineering plastics to ±0.05 mm.
- Vacuum casting — 20–100+ polyurethane parts with production-grade finishes.
- Mold making — tooling for low-volume production runs.
- Finishing — painting, electroplating, silk-screen, anodizing and assembly.
Across the chain, SLA holds ±0.1 mm and CNC reaches ±0.05 mm — the numbers that matter once a part has to actually fit.
Why a single accountable partner wins
- Speed you can plan around. First articles in 24–72 hours, shipped DDP to 30+ countries, with dimensional reports on every order.
- Single accountability. One engineer owns the job from DFM review to shipment — no finger-pointing between vendors.
- IP stays contained. With no multi-supplier relay, drawings and specs never leave a single closed loop.
- Consistency. One process chain means one standard, applied the same way from prototype to pilot run.
Industries we serve
Robotics and humanoids, smart hardware, industrial equipment, cultural & creative, medical & dental, and automotive & transport — anywhere a part has to be precise, presentable and on time.
How to start: 4 steps
- 1. Upload CAD — send STEP, IGES or STL with quantity, material and finish.
- 2. DFM review — an engineer checks manufacturability and picks the optimal process.
- 3. Quote in 24h — a detailed, itemized quote, not an auto-estimate.
- 4. Build & ship — we produce, inspect and ship worldwide with full reports.
Proven in demanding programs
Jinghui 3D is the source factory behind precision components for humanoid-robot leaders such as Unitree and UBTECH — the kind of program where tolerance, consistency and confidentiality are non-negotiable.

FAQ
Q1: What does "vertically integrated" mean for prototyping?
A: Every step — design, printing, machining, casting, finishing — is done in our own plant, so you manage one partner instead of several vendors.
Q5: Do you protect IP / sign NDAs?
A: Yes. Because production stays in one closed loop with no outsourcing, drawings and specs are contained; NDAs are available on request.
