Dongguan TC Precision Machining Co., Ltd. combines laser powder bed fusion with 3-, 4- and 5-axis CNC finishing under one roof. Overseas OEMs and engineering teams use us to turn complex CAD models into functional prototypes, robot structural parts, precision gears and low-volume production components.
Our engineers bring 10+ years of hands-on machining and additive experience. Instead of forcing one process, we review every drawing for manufacturability and plan the shortest, most reliable route: print where geometry demands it, machine where tolerance demands it.
From a single rapid prototype to repeat production orders, each capability below is engineered to feed the next, so parts move from printer to machine to inspection without hand-offs between suppliers.
CAP / 01 Simultaneous 5-axis milling reduces setups on complex housings, impellers and robot joints, keeping datums consistent and positional tolerances tight.
CAP / 02 Dense copper, titanium and stainless parts with internal channels that cannot be drilled or cast.

Prototype parts CAP / 05Bridge production and end-use parts in metals and engineering thermoplastics, with repeatable process records.
Production parts CAP / 06Lightweight jigs, fixtures, gauges and end-of-arm tooling printed in carbon-fiber composites.
Tooling examples CAP / 073D printed hollow bent pipes, manifolds and conformal cooling channels in metal powders, thermoset resins and thermoplastics, finished by CNC at every sealing and mating surface.

On CNC-finished features
Sourcing from overseas is a risk decision. We reduce that risk with engineering transparency, single-source accountability and inspection data you can verify.
Print the complex geometry, machine the critical interfaces. One accountable supplier instead of two vendors and a gap in between.
Engineers review wall thickness, overhangs, support access, tool reach and tolerance stack-ups, then suggest changes that lower cost without compromising function.
Every batch is inspected against your drawing. Measurement records and material traceability travel with the parts, so incoming inspection on your side is faster.
STEP, IGES or STL models plus 2D drawings with tolerances.
Process route, material and risk points confirmed by engineers.
Additive build, heat treatment and CNC finishing in-house.
Measurement report, export packing and global delivery.
A practical starting point for choosing the right material and process. Final recommendations are confirmed during DFM review of your drawing.
| Material | Recommended Process | Typical Applications | Engineering Note |
|---|---|---|---|
| Pure Copper / CuCrZr | Green-laser LPBFCNC finish | Heat exchangers, induction coils, cold plates, electrical conductors | Green light (~515 nm) is absorbed far better than 1064 nm infrared, enabling dense, conductive copper. |
| Titanium Ti6Al4V | LPBF5-axis CNC | Lightweight robot arms, brackets, aerospace-style structures | High strength-to-weight ratio; stress relief before machining protects dimensional stability. |
| Stainless Steel 316L | LPBFCNC | Fluid manifolds, hollow bent pipes, food and chemical equipment | Excellent corrosion resistance; internal channels can be printed, sealing faces machined. |
| Aluminum 6061 / 7075 / AlSi10Mg | CNCLPBF | Housings, enclosures, fixtures, automotive prototypes | Wrought grades for machining; AlSi10Mg for printed thin-wall, lattice and topology-optimized parts. |
| Alloy & Gear Steels | CNC turningGear cutting | Power transmission gears, shafts, couplings, actuator components | Heat treatment specified to balance surface hardness and core toughness. |
| Carbon-Fiber Composites | Composite printing | Jigs, fixtures, end-of-arm tooling, lightweight structural parts | Stiff and light; ideal for replacing machined aluminum tooling in low quantities. |
As-printed metal surfaces typically hold ±0.1–0.2 mm. When your drawing calls for tighter limits, we add machining stock and finish bores, threads and sealing faces on CNC.
We work alongside equipment makers, technology companies and industrial brands who rely on consistent quality across repeat orders.
We recognize that every market has its own standards, documentation and logistics needs. Parts leave our facility export-packed and tracked to customers across five continents.
Dongguan Russia South Korea Australia Canada Brazil Nigeria Our engineering team follows technology shifts that will change how precision parts are designed and sourced, and shares what they mean for buyers.
01Volumetric printing cures an entire part at once rather than layer by layer, opening new routes for soft-hard composite structures.
02Large-format robotic printing shows how additive processes and automation are converging, raising demand for precision robot components.
03AI-driven parameter tuning and in-process monitoring are making metal printing more predictable, from first article to repeat batch.
