    Never. Unlike platforms that add 15-30% broker fees, we offer all-inclusive pricing:
    Online Quotes: Includes tariffs specified(if any), mill certs and shipping.
    Change Orders: Design modifications pre-production are free. Post-production adjustments incur costs only with written approval.
    Volume Discounts: Save up to 30% on 500+ units.

    Yes – we specialize in high-complexity work:
    Multi-Axis Machining: 5-axis milling for contours/undercuts; 11-axis mill-turn for large aerospace components.
    Tolerance Expertise: ±0.025mm standard. Achieve ±0.005mm with CMM validation.
    Large Parts: Machine components up to 2,000 × 1,000 × 500mm.

    Industry-leading speed without premium pricing:
    Prototypes: 1–3 days (machined metals/plastics).
    High-Volume: 10,000+ parts in 14 days.
    Real-time tracking and daily production updates prevent delays.

    Metals: Titanium, stainless 316L, aluminum 7075-T6.
    Plastics: FDA-compliant PEEK, Ultem 1010, Radel® PPSU.
    Finishes: Anodizing (Type II/III), passivation, Ni-Teflon plating, MEDCOAT™ for implants.
    Full material certifications (RoHS, REACH, FDA) provided with every order.

    Your security is non-negotiable:
    NDA/IP Agreements: Enforced at supplier and employee levels. Designs are purged post-production.
    Certifications: ISO 9001:2015, ISO 13485:2016 (medical), AS9100D.

    Save 15-30% without sacrificing quality:
    Small-Batch Optimization: Nest multiple parts in one setup to reduce costs by 40% .
    Price Match: We beat any validated quote from competitors .

    Our quality assurance is fundamentally different. Unlike marketplace models that rely on supplier self-reporting, we perform 100% in-house, physical inspections at our facility. Every part is validated using CMMs, optical comparators, and precision hand tools against your drawing. We include free inspection reports and material certifications with every order, while competitors often charge extra for these critical documents. This hands-on approach ensures ±0.025 mm tolerances and prevents the post-delivery surprises common with broker platforms.

    We machine over 50+ metals and engineering-grade plastics, from common aluminum 6061 and 303 stainless to exotic alloys like Titanium Gr5, and PEEK. Crucially, we provide full material traceability (mill test reports) for every project at no additional cost. This includes compliance with RoHS, REACH, and ASTM standards, which is essential for aerospace, medical, and automotive applications.

    Our standard machining tolerance is ±0.025 mm, which meets the needs of most applications. We can consistently hold ±0.025 mm for critical features and, depending on the part geometry and material, can achieve ±0.020 mm for milling and ±0.015 mm for turning. All tight tolerances are validated with in-house CMM inspection to ensure compliance.

    Yes, and it's a core part of our service. Within hours of uploading your CAD file, our engineers—not an automated algorithm—provide actionable DFM analysis. We flag potential issues like thin walls, sharp internal corners, difficult-to-machine features, and tolerance conflicts, along with specific suggestions to reduce cost and improve manufacturability, all at no charge.

    We accept all major CAD formats, including STEP, IGES, SLDPRT. For full drawing specification, you can also upload PDFs with GD&T. Our system automatically analyzes your 3D model and provides online pricing, lead time, and preliminary DFM feedback.

    Absolutely. We specialize in seamless scaling:
    Prototyping: 1-10 parts.
    Low-Volume/Batch Production: 10 - 10,000 parts.
    High-Volume Production: 10,000+ parts. Our connected network of partners allows us to optimize the manufacturing process for any volume, ensuring consistency from your first prototype to full-scale production.

    You have full visibility through our online customer portal. From this dashboard, you can:
    • Review and approve quotes.
    • Message your dedicated project engineer.
    • View real-time production updates and photos.
    • Access and download inspection reports and material certs pre-shipment.
    • Track shipping and delivery. This level of transparency eliminates the "black box" experience of other platforms.
