Frequently
Asked Questions

Find quick answers regarding our aluminum CNC machining processes, material options, strict quality standards, and global delivery timelines.



What is your Minimum Order Quantity (MOQ)?

We have no strict MOQ. Whether you need a single prototype or mass production of 10,000+ parts, we can easily accommodate your needs.

Will you sign a Non-Disclosure Agreement (NDA) to protect my IP?

Absolutely. We gladly sign NDAs before you upload any files. Your designs and intellectual property are kept 100% secure and confidential.

Which aluminum alloys do you most commonly machine?

We extensively work with aerospace and industrial-grade aluminum alloys, most notably 6061-T6 , 7075-T6 , 5052 , and 2024 . These materials offer an excellent balance of machinability, strength-to-weight ratio, and corrosion resistance.

What is your standard turnaround time for prototypes vs. mass production?

Rapid prototypes typically ship within 1 to 5 business days. For low-volume production (100-1,000 parts), lead times average 5 to 15 days. High-volume mass production runs are scheduled based on batch sizes, usually taking 2 to 4 weeks.

How quickly can I get a quote for my project?

Our engineering team reviews your files and typically provides a detailed, comprehensive quote within 12 to 24 hours. Complex multi-part assemblies may require slightly more time for accurate manufacturing evaluation.

What CAD file formats do you accept for quoting?

We accept all major 3D and 2D CAD formats. For 3D models, STEP (.stp/.step) and IGES (.igs/.iges) are preferred. For 2D drawings (which are essential for checking tolerances and threads), PDF or DWG formats are ideal.
