FAQs

    Q My design is proprietary. How do you protect my IP?

    A We take client intellectual property (IP) extremely seriously. We are happy to sign a Non-Disclosure Agreement (NDA) before discussing your project. All customer files are stored on secure servers with access limited to essential project personnel. Your design will never be shared or used for any other purpose without your explicit permission.

  • Do you offer assembly services?

    Yes. We provide value-added services beyond machining, including cleaning, deburring, press-fit assembly, thread locking, and adhesive bonding, saving you time and simplifying your supply chain.

  • Do surface finishes affect part dimensions?

    Yes, they can. Coatings like anodizing or plating add a layer of material to the part surface, typically measured in microns (thousandths of a millimeter). If your part has critical functional dimensions, inform us beforehand so we can apply a pre-plate dimension compensation during machining.

  • What surface finishing options do you offer?

    We offer a wide range of finishes, including:

    • Anodizing (Type II & III): For aluminum, improves wear and corrosion resistance.

    • Bead Blasting / Sandblasting: Creates a uniform matte texture.

    • Plating: Such as nickel, chrome, or zinc plating for hardness and corrosion resistance.

    • Electroless Nickel Plating: Provides a uniform coating on complex geometries.

    • Passivation: For stainless steel, enhances rust resistance.

    • Painting & Silk Screening: For aesthetic parts.

  • Can I get inspection reports?

    Absolutely. For critical parts, we can provide full inspection reports (including dimensional data and material certifications) upon request for complete transparency.
