Frequently Asked Questions
What is Radii?
Radii is an AI-powered manufacturing platform that connects businesses with qualified manufacturing partners in Mexico. We manage the full lifecycle (quoting, sourcing, quality control, and delivery) so you get custom parts without managing the supply chain.
What manufacturing processes do you support?
CNC Multiaxis, CNC Lathe and Injection Molding. If your process isn't listed, submit a request and our team will find the right partner.
How do I get a quote?
Upload your CAD files (STEP, IGES, STL, or OBJ), configure each part with quantity, material, tolerance, and finishing options, and receive pricing immediately for eligible parts. The whole process takes minutes. Parts that require manual review are priced by our sales team.
What are the lead time options?
Urgent: 1–5 business days. Standard: 10 business days. Economy: 30 business days.
What payment methods do you accept?
Credit/debit cards (Stripe), OXXO cash payments (Mexico, MXN only), purchase orders, and bank wire transfers. We support USD, MXN, and EUR.
How do you ensure quality?
Every order goes through a dedicated quality control stage before shipping, including, if needed, PPAP documentation, inspection processes, and certification tracking. If issues are found, the part is remanufactured before delivery.
How can I track my order?
Your order progresses through clear stages and all the process is visible in real time through your account.
Why manufacture in Mexico?
Geographic proximity to US markets, competitive costs, USMCA trade benefits, and a strong industrial base. You get shorter lead times and lower logistics costs compared to overseas sourcing.
What happens if there's an issue with my parts?
After delivery, you can raise an objection directly through the platform. We work with the manufacturing partner to resolve it: rework, replacement, or credit.
