Custom CNC Machined & Molded Parts Across Global Industries
From flight-critical aerospace components to surgical instruments and automotive powertrain prototypes, we bridge the gap between CAD design and physical manufacturing—delivering functional prototypes in 4–8 business days ex-factory. Explore all Industry Manufacturing Solutions.
Automotive Engineering
5-Axis Ti-6Al-4V turbocharger compressor wheels, 7075-T651 suspension steering knuckles, 4140 splined stub shafts, and EV battery & inverter housings.
Accelerate powertrain and chassis R&D with road-ready, dyno-tested functional prototypes delivered in 4–8 business days ex-factory—allowing engineering teams to validate dynamic balance and physical fit without waiting for costly production tooling.
Medical & Surgical Devices
Biocompatible titanium (Ti-6Al-4V) bone plates, surgical instruments & forceps, endoscopic camera housings, and microfluidic manifold blocks.
De-risk pre-clinical trials and surgeon evaluations with precision biocompatible parts machined from traceable implant-grade PEEK and 316L/titanium, ensuring zero oil contamination and complete dimensional traceability.
Consumer Electronics & IoT
CNC aluminum unibody chassis, ultra-thin copper heatsinks & vapor chambers, wearable metal frames, and optical-clear PC/acrylic covers.
Fast-track your CMF (Color, Material, Finish) validation and thermal dissipation trials. We deliver fully assembled functional prototypes so your team can finalize ergonomics and snap-fits before committing to multi-cavity tooling.
Aerospace & Defense
5-Axis monolithic turbine impellers, 3-axis pocketed 7075-T651 airframe brackets, avionics chassis enclosures, and 17-4PH/Ti-6Al-4V hydraulic manifolds.
Machine flight-critical components from traceable 7075-T651 aluminum, Ti-6Al-4V, and Inconel billets—combining 3/4-axis structural pocketing with simultaneous 5-axis contouring and Zeiss CMM verification to ±0.010 mm (±0.0004″) upon request.
Robotics & Automation
Articulated robot arm linkages, harmonic drive housings, multi-axis pneumatic gripper fingers, AGV/AMR sensor mounts, and vacuum-cast protective bumpers.
Eliminate mechanical backlash and joint inertia in your automated systems. We fabricate high-rigidity, low-mass structural linkages and end-effectors in days, helping robotics teams test real payload cycles rapidly.
Commercial & Optical Lighting
Diamond-milled optical PMMA light guides & TIR collimator lenses, radial finned aluminum LED heatsink housings, and IP68 outdoor luminaire bezels.
Verify optical beam patterns, lux distribution, and thermal dissipation upfront. Our diamond-machined clear optics provide 92%+ light transmittance with zero birefringence, proving your optical design before mass molding.

Frequently Asked Questions About Rapid Prototyping & CNC Machining
All quoted lead times represent ex-factory production and inspection turnaround (excluding 3–5 days DHL/FedEx/UPS international air transit): simple prototypes ship in 4–8 business days, surface-finished prototypes in 7–12 business days, batch CNC runs (10–1,000+ pcs) in 7–30 business days, and rapid tooling/injection molding in 12–35 business days (simple aluminum T1 samples in 12–18 business days).
Absolutely, we prioritize the confidentiality and security of your drawings. We are more than willing to sign a Non-Disclosure Agreement (NDA) before receiving your drawing, ensuring the utmost protection of your intellectual property. You can trust that your drawings will be handled with the highest level of confidentiality and kept secure throughout our collaboration.
Certainly, we have the capability to create measurements based on your samples and generate drawings for the production of machining parts. Our team will carefully analyze and assess your samples to ensure accurate replication and precise manufacturing of the desired parts.
If any delivered component deviates from your approved 2D drawing tolerances or specifications, submit inspection photos or dimensional reports to our in-house engineering team. We perform immediate root-cause verification against our quality records and promptly rework or remake non-conforming parts at no additional fabrication cost.
Please provide us with your 3D CAD drawing files (STEP, IGES, or X_T) along with your 2D PDF drawings. Additionally, kindly specify the desired material, surface treatment requirements, and the quantity you require. Once we have this information, our engineering team will promptly review your model and prepare a comprehensive quotation within 24 hours.
Our Minimum Order Quantity (MOQ) is 1 piece, supporting everything from single-unit engineering verification prototypes to 1,000+ piece low-volume production runs.
Our in-house quality team executes a four-stage verification protocol across every order:
- Incoming Material Verification: Mill Test Report (MTR) review, preliminary dimensional checks, and ASTM E18 hardness verification on raw stock.
- First Article Inspection (FAI): Full critical-to-quality datum verification in our 20 °C ± 1 °C metrology lab before batch release.
- In-Process Patrol Sampling: Statistical Acceptable Quality Limit (AQL) dimensional sampling during machining using calibrated pin/thread gauges and non-contact 2.5D Optical Vision Measuring Systems (VMS).
- Pre-Shipment Screening & Reporting: 100% visual/cosmetic and critical go/no-go gauge inspection before packing, with full-dimension Zeiss CMM reports available upon request.
Payment terms depend on order size. Larger orders require a down payment with the order, with the balance due before shipping; smaller orders are paid in full before shipping. Your quote confirms the exact terms.
Yes, we support Original Equipment Manufacturer (OEM) orders, including custom laser marking, silk-screen branding, and protective export packaging. Upload your CAD files and specifications via our quote form for custom project evaluation.
