Frequently Asked Questions by Global Engineers

Transparent, data-backed answers on machining tolerances, metrology reports, lead times, intellectual property protection, and international logistics.

Every successful production run starts with a rigorous manufacturability review. Once you upload your 3D CAD file (.STEP, .STP, .IGS, or .STL), our senior tooling engineers conduct a comprehensive Design for Manufacturability (DFM) review within 2 hours.

We analyze:

  • Wall Thickness Minimum wall feasibility to avoid sink marks or cutting vibrations.
  • Internal Radii Ensuring corner radii match standard end-mill diameters to eliminate extra EDM tooling costs.
  • Draft Angles Verifying 1° to 3° draft for clean injection mold part ejection.
  • Tolerances Identifying critical vs. non-critical dimensions to optimize cycle time and save unit cost.

If any feature increases risk, we propose actionable CAD adjustments so your part moves into production with complete confidence.

We operate 24/7 CNC machining shifts in our Shenzhen facility to meet tight hardware launch deadlines:

  • Rapid CNC Prototypes: 1 to 3 business days (24h expedited dispatch available for critical milestones).
  • Sheet Metal & Laser Enclosures: 3 to 5 business days.
  • Rapid Tooling & Bridge Injection Molding: 7 to 14 days (including T1 sample approval).
  • 3D Printing & Additive: 24 to 48 hours.

We ship internationally via DHL Express, FedEx Priority, and UPS Air Freight, delivering directly to your facility in North America, Europe, Australia, or Asia within 3 to 5 days with full online tracking and prepaid customs clearance (DDP available).

Yes. As an ISO 9001:2015 certified manufacturer (Cert No. 29024010637-03R0S), quality documentation is an integral deliverable with every shipment. We provide:

  • Full 3D Zeiss CMM Inspection Report: Point-by-point dimensional verification against 2D drawings with GD&T validation.
  • First Article Inspection (FAI): AS9102-standard documentation for aerospace and medical applications.
  • Raw Material Mill Test Certificate (MTC / MTR): Verifying metallurgical chemical composition and mechanical tensile strength.
  • RoHS 2.0 & REACH Compliance: Certificates confirming absence of restricted hazardous substances.

Intellectual Property security is our foundational protocol. We strictly enforce:

  • Bilateral Non-Disclosure Agreement (NDA): We sign bilateral NDAs before you share CAD files, protecting your technical designs and patent rights.
  • Encrypted File Storage: Project geometries and CAM files are stored on isolated, firewall-protected servers with strict role-based access.
  • No Public Showcase Without Consent: We never display customer parts, photographs, or case studies on our website or social media without written authorization.

With our modern fleet of 3-Axis, 4-Axis, and continuous 5-Axis machining centers alongside precision wire EDM, we achieve:

  • Standard Tolerances: ±0.01 mm (±0.0004 in) conforming to ISO 2768-m.
  • High-Precision Critical Tolerances: Down to ±0.005 mm (±0.0002 in) for bearing journals and optical alignment pins.
  • Surface Finishes (30+ Options): Type II Anodizing (matte/gloss in any color), Type III Hardcoat Anodizing (50µm wear layer), Electroless Nickel, Hard Chrome, Powder Coating (RAL / Pantone), Bead Blasting (glass bead grit 100-220), Passivation, and Mirror Optical Polishing down to Ra 0.2µm.

There is strictly No Minimum Order Quantity (Zero MOQ).

You can manufacture a single 1-piece prototype for fit verification, 50 parts for EVT pilot assembly, or 250,000 units for mass commercial production. Our tiered pricing automatically lowers the unit cost as batch size scales, providing you factory-direct competitiveness at every production volume.
