Trusted by OEMs and Tier-1 suppliers in Europe, North America & Japan.
Lower project risk and shorten development cycles with one-stop manufacturing in China — from DFM review and tooling to validated mass production with documented process capability. Ideal for CNC & mold manufacturing projects in aerospace, robotics, medical and EV sectors.
Engineers looking for a reliable China CNC machining services and injection mold manufacturing partner in China choose Super-Ingenuity (SPI) to reduce project risk, keep tolerances under control and move from prototype to stable production faster.
Our precision CNC services in China are built around repeatability. Process windows, tool paths and fixturing are tuned so that critical dimensions stay where they should be across the whole batch.
Typical capability: ±0.002 mm on key CNC features · Stable positional accuracy for tight assemblies and inserts.
The same engineering team that reviews your RFQ supports first articles, pilot runs and serial production, reducing the risk of issues when scaling from prototypes or T0/T1 shots to mass production.
3–7 day lead time for prototypes · CPK ≥ 1.67 targeted in serial runs · CMM reports and capability data for FAI / PPAP.
You talk directly with engineers who understand both CNC machining and mold manufacturing, so you get realistic feedback on tolerances, draft, wall thickness and tool access before committing budget.
English & Japanese support · Practical DFM suggestions instead of generic “can / cannot” answers.
SPI components are already running in the field — from aerospace and robotic vision systems to medical devices and EV platforms — where failure is not acceptable.
Experience with aerospace brackets, vision-sensor housings, medical components, automation frames and EV mold inserts for OEM and Tier-1 customers.
Manufacturing & tooling services
One coordinated team in Dongguan supporting export molds, rapid tooling, precision CNC machining, Swiss-type turning, 3D printing, vacuum casting, sheet metal fabrication, and sand casting — from quick-turn prototypes to stable mass production.
We provide custom injection molding services in China for prototypes, bridge builds and series production, with resins and finishes matched to your end-use.
Export molds
Export-ready injection mold making in China, designed around your press, mold standard and lifetime targets, with complete documentation.
Cost-effective aluminum and soft-steel tooling when you need real molded parts quickly, before long-life tools.
Model & display
Show-quality plastic model molds for exhibitions, photography and investor demos that look like final parts.
Silicone molds and polyurethane resins for production-like plastic parts in low volumes, without hard tooling.
Our precision CNC machining services in China focus on tight-tolerance custom machined components in aluminum, stainless, titanium and engineering plastics.
Our automatic lathe services are built for long, slender and micro-feature parts where stability, concentricity and cycle time matter.
We offer 3D printing services including SLA, SLS and other processes for complex, lightweight parts and fast design validation.
Our sheet metal fabrication services cover laser cutting, bending and welding for enclosures, brackets and custom metal assemblies used in industrial equipment.
Sand casting
We provide sand casting services for larger or heavier metal parts where durability and unit cost are key.
Upload your CAD files once — we handle DFM, quoting, prototyping and mass production for precision CNC machining & mold manufacturing projects in China.
Send your STEP, STP, IGES, SLDPRT or PDF drawings via our RFQ / contact form. Our engineers review manufacturability, tolerances, materials and risk points before we cut any metal.
What it means for you: fewer back-and-forth emails, fewer surprises, and a lower chance of redesign or scrap later in the project.
Receive a clear quotation with unit price, tooling cost (if needed), suggested process route and realistic lead time based on your quantities and shipping destination.
What it means for you: you can compare options, secure budget and plan your build schedule early, with no hidden costs later.
We produce prototypes or small batches and provide CMM / inspection reports on critical dimensions so your team can validate fit, function and key tolerances before ramp-up.
What it means for you: data-backed approval of parts, fewer on-site visits and fewer iterations when you move to pilot builds.
After you approve samples, we lock tools, fixtures and CNC programs, then run mass production with SPC monitoring and CPK ≥ 1.67 on key features.
What it means for you: stable quality, fewer line stops and less rework risk over the lifetime of your CNC or mold program.
To get a CNC machining quote in China, send your 3D CAD files (STEP, STP, IGES, SLDPRT) and 2D drawings with material, quantity, tolerances, surface finish and any quality requirements. Our engineers review manufacturability, choose the right process and return pricing and lead time, usually within 24 hours.
Most of our precision CNC machining and mold manufacturing work sits between “one-off prototypes” and “full automotive volume”. We are a strong fit for high-mix, tight-tolerance and export programs — and usually not the best choice for ultra-high-volume, pure cost-driven commodity parts.
Frequent design changes · 1–500 pcs per lot
Ideal for robotics, aerospace brackets, fixtures and sensor housings where designs evolve quickly and volumes stay modest. You can update drawings without “restarting” the whole supplier onboarding process.
Example: robotic vision-sensor housing in 7075 aluminum, ~50 pcs per batch, revised every 2–3 runs.
Not a great fit if you only buy millions of identical, low-mix parts where the lowest possible unit price is the only priority.

For teams who prove a design with small CNC batches or rapid tools, then need a controlled ramp to stable production without dimensions drifting or cosmetic issues appearing later.
Example: EV battery cooling plate machined in 6061, from 20 pcs prototype lots to ~2,000 pcs per year.
Less suitable if you only need a one-time prototype and plan to move volume tooling entirely to another supplier.
See how we handle prototype-to-production transfer →Preventing issues before machining or tooling starts
Best for precision parts where flatness, true position or surface finish truly matter, and you want honest feedback before committing to expensive tooling or complex CNC programs.
Example: thin-wall 7075 bracket with ±0.02 mm flatness over 150 mm, or medical stainless-steel part with Ra ≤ 0.4 μm cosmetic requirement.
Not ideal for very coarse-tolerance, purely cosmetic parts where a low-cost job shop without DFM is enough.

A simple 5-step flow so you always know the next action, who is responsible, and what documents you will receive at each stage.
Send STEP/IGES and 2D drawings with material, tolerances, finish, and quantity. We can sign your NDA or provide ours before any file review.
Our engineers perform DFM checks (thin walls, tool reach, tolerance feasibility, surface finish) and send pricing, lead time, and suggestions — usually within 24 hours.
After PO and terms are confirmed, we lock the drawing revision, freeze the BOM, and schedule machining, tooling, or molding in our production plan.
CNC, molding, or other processes start with first-article checks, in-process measurements, and SPC/CPK tracking on key features where required.
CMM reports, visual checks, and packing are completed before DHL/FedEx or air/sea shipment. Inspection data and photos are shared together with tracking details.
Typical lead time: CNC prototypes in 3–7 days · Rapid molds in 10–15 days · Production molds in 20–30 days, depending on complexity and quantity.
