Industrial Additive Engineering Showcase
Explore our custom metal powder bed fusion and CNC-machined structural parts engineered for automotive, thermal, robotic, and mission-critical fluid applications.
Dongguan TC Precision: Engineering-Led Additive Manufacturing
Operating from the precision manufacturing hub of Dongguan, China, Dongguan TC Precision Machining Co., Ltd. resolves the trade-off between the geometric freedom of metal powder printing and the microscopic tolerances required by mechanical assemblies. By pairing industrial Laser Powder Bed Fusion (LPBF) with secondary 5-axis CNC machining centers under a unified quality assurance regime, we eliminate the friction, datum errors, and supply chain fragility common to multi-vendor production.
Macro-Industry Solutions & Component Engineering
Our powder bed fusion systems address structural, thermal, and fluid dynamics challenges that traditional machining, investment casting, and brazing cannot solve.
Aerospace & Defense Systems
Topology-optimized structural brackets, flight-ready turbine manifolds, and satellite propulsion nozzles manufactured in Ti6Al4V Grade 5 and nickel superalloys (Inconel 718). LPBF allows organic, lightweight lattice fills that achieve up to 65% weight reduction while maintaining ultimate tensile strength across high-G load vectors.
- Isotropic mechanical strength post-HIP
- Conformal cooling jacket integration
- Comprehensive full lot traceability
Semiconductor & Power Electronics
Ultra-dense pure copper (Cu-ETP/C11000) and CuCrZr heat sinks printed with proprietary 515 nm green lasers. By avoiding the 95%+ infrared reflection of conventional Nd:YAG systems, we achieve >99.8% sintered density with thermal conductivities reaching 390 W/(m·K), perfect for next-gen wafer chucks and high-power IGBT liquid cold plates.
- No weld seams or brazing flux voids
- Helium leak tested down to 1x10⁻⁹ mbar·l/s
- Complex micro-channel cooling matrices
Robotics & Dynamic Automation
Collaborative robot structural arms, bionic end-effectors, and hollow high-reduction cycloidal power gears. By combining thin-wall additive structures with CNC-turned gear profiles, we slash rotational inertia, enabling higher joint accelerations, reduced motor draw, and tighter positioning repeatability in industrial work cells.
- Integrated conduit passages within arms
- Hardened alloy steel gear profiles
- High dynamic torsional rigidity
China Factory 4.0: Supply Chain Resilience & Speed
Situated in the Greater Bay Area hardware ecosystem, TC Precision turns global manufacturing bottlenecks into streamlined digital pathways through full supply chain vertical integration.
Localized Raw Feedstock
Direct supply agreements with domestic plasma-atomized spherical powder mills guarantee consistent batches of virgin Ti6Al4V, 316L, and AlSi10Mg with strict control over oxygen content, satellite beads, and PSD flowability.
Integrated Secondary CNC
Additive parts remain registered on standardized zero-point clamping fixtures during the transition from the printer baseplate to the 5-axis machining center, preventing datum loss across geometric transformations.
In-House Heat Treating
Atmospheric vacuum annealing, solution heat treatment, and Hot Isostatic Pressing (HIP) relationships ensure internal pore closure, microscopic stress release, and fatigue behavior matching wrought stock.
Rapid Prototype to Production
From one-off DFM validation within 48 hours to mid-volume runs of 10,000 units, our digital factory scheduling adjusts machine parameters smoothly without costly tooling changeovers.

Meeting Global Enterprise Sourcing & Procurement Demands
Procuring additively manufactured metal parts internationally requires reliable risk management. TC Precision provides rigorous process verification and supply security for Tier-1 supply chains.
Quality Verification & Traceability
Every powder lot comes with chemical composition reports (ASTM B214/B215) and full optical microscopy data. Finished components include full CMM coordinate measuring reports, 3D laser scan surface deviation maps, surface roughness (Ra) charts, and X-ray computed tomography (CT) porosity validation upon request.
IP Protection & Legal Assurances
We work with enterprise partners under enforceable Non-Disclosure Agreements (NDAs). Design files (STEP, IGES, STL) are kept on isolated, air-gapped secure local servers with granular access controls, protecting your proprietary geometry, patents, and project timelines.
Export Packaging & DDP Logistics
Metal printed components undergo ultrasonic cleaning, desiccated vacuum wrapping, and custom foam-lined wooden crating to prevent surface oxidation or transport damage. We offer complete Incoterms support, from EXW to DDP with air or sea freight clearance delivered straight to your assembly line.
Technology Roadmap & Additive Horizon Outlook
Our engineering laboratory continuously expands powder metallurgy frontiers to unlock higher production throughput and broader material compatibility.
Multi-Beam Large-Format Powder Beds
Deploying quad-laser and 8-laser LPBF platforms with build volumes up to 800 x 800 x 1000 mm. Overlapping optical scan-field calibration and active melt-pool plume evacuation enable seamless, monolithic aerospace structural parts without weld lines or thermal distortions.
Functionally Graded Multi-Material Fusion
Developing dual-powder deposition systems capable of transitioning continuously between pure copper (for localized heat rejection) and high-strength nickel or titanium alloys (for structural flanges) in a single consolidated part, eliminating assembly seams.
AI In-Situ Layer Closed-Loop Monitoring
Integrating high-speed co-axial pyrometers and optical cameras with machine learning algorithms. Real-time melt pool anomaly detection automatically adjusts laser power, scan velocity, and recoater travel to eliminate defects before the next layer is spread.
International Compliance & Localized Technical Support
Engineering collaboration should be clear and accessible. TC Precision pairs English-fluent DFM project engineers with structured international quality assurance standards.
ISO & ASTM Standards Conformance
Production runs adhere strictly to ISO 9001 quality systems and ISO/ASTM 52900 guidelines for additive manufacturing. Secondary CNC work conforms to ISO 2768 (medium/fine) and ISO 1101 geometric dimensioning and tolerancing (GD&T) standards.
Direct English DFM Communication
You work directly with experienced mechanical engineers rather than non-technical sales agents. Every drawing undergoes review for wall thickness, overhang angles, thermal heat accumulation, and cutter accessibility, with feedback returned within 24 hours.
Environmental & RoHS Compliance
All metal powders, protective atmospheres, and chemical finishing passivations comply with EU RoHS and REACH directives. We maintain zero-landfill metal powder recycling protocols that reclaim unused powder via multi-stage vibratory sieving.
