Frequently Asked Questions

 
Do you provide First Article Inspection (FAI) reports for high-precision parts? +

Yes, we can provide comprehensive FAI reports and material certifications to ensure all dimensions and materials strictly comply with your engineering drawings.

Can you assist with the design for manufacturability (DFM) of complex instrument housings? +

Absolutely. Our engineering team reviews all CAD files to optimize bend radii, hole placements, and fastener selections to improve quality and reduce manufacturing costs.

Can you ensure the laser engraving won't fade in harsh industrial environments? +

Yes, laser engraving actually etches into the metal surface, making it permanently resistant to wear, chemicals, and UV exposure compared to traditional stickers.

What is the minimum material thickness for secure PEM nut insertion? +

Generally, we recommend a minimum material thickness of 1.0mm for standard PEM fasteners to ensure maximum pull-out and torque-out resistance.

What is your Minimum Order Quantity (MOQ) for prototypes? +

We have no strict MOQs for initial prototypes. We support high-mix, low-volume (HMLV) manufacturing to help you thoroughly verify designs before moving to mass production.
