Every Process You Need.
One Strategic Partner.
From single-piece prototypes to production runs, Baja Supplies manages the full sourcing cycle — quality oversight, documentation, and border logistics included.
3 and 4-axis CNC milling for enclosures, brackets, housings, heat sinks, and structural components. Aluminum 6061-T6, 7075-T6, stainless steel, titanium, and engineering plastics. ISO 9001 certified suppliers. CMM-verified first articles on every new part number.
Precision CNC turning for shafts, axles, bushings, spacers, threaded fittings, and rotational components. Live-tool lathes add keyways and cross-holes in a single setup.
Functional prototypes and end-use parts with no tooling cost. FDM for large volumes and fast turnaround, SLA for precision details, SLS for engineering-grade nylon end-use parts.
Delrin, PEEK, Nylon, UHMW, Polycarbonate, and PTFE machined to tight tolerances. No injection mold tooling required. FDA-compliant grades available with full material documentation.
From approved drawing to CMM-verified first article in 5–10 business days. DFM feedback included with every quote. The same supplier that makes your prototype handles production — no re-qualification.
Industry-Specific

What We Can Do
Right Now
Capabilities available immediately through our certified supplier network in Tijuana and Mexicali.
From File to Dock
in 5–15 Days
One point of contact. One purchase order. One documentation package. Baja Supplies handles the complete sourcing cycle so your team doesn’t manage a foreign supplier.
Send your STEP file, 2D drawing, material spec, quantity, and quality requirements. Any CAD format accepted. We send you the NDA — not the other way around.
Our engineering team reviews for manufacturability and returns a quote with pricing, lead time, and specific DFM feedback — features to modify that would reduce cost or lead time.
We match your program to the right certified supplier — by material capability, quality system, machine capacity, and track record. One PO, one invoice, one relationship.
First articles CMM-verified before the production run approves. Documentation package assembled — CoC, MTR, FAI, special process certs. Parts and docs ship together.
Not a Marketplace.
A Strategic Partner.
The difference between Baja Supplies and an online quoting platform is the same as the difference between a sourcing partner and a vending machine.
We match your job to the shop with demonstrated capability for your material, tolerance, and industry — not just the next available machine. Availability alone is never the selection criterion.
You can drive to our suppliers, walk the floor, and witness a CMM inspection — and be back in San Diego before lunch. The auditability of a domestic supplier at nearshore cost.
FAI, MTR, CoC, Cpk, PPAP, AS9102 — assembled and reviewed before parts ship. Documentation requirements confirmed at RFQ time, not discovered at receiving.
One email, one invoice, one phone call. You don’t manage a Mexican supplier — we do. Your team spends time on engineering, not on supplier coordination.
USMCA provides the strongest IP protection framework available for cross-border manufacturing. Your CAD files never leave a secured, NDA-protected supply chain.
The supplier that produces your first articles transitions to production on the same drawing. No re-qualification, no supplier transition, no documentation restart.
Tijuana vs. Domestic
vs. Asia
The same quality as a domestic shop, the cost profile of offshore, and the logistics of a local supplier.
| Factor | U.S. Domestic | Baja Supplies — Tijuana | Asia / Low-Cost Country |
|---|---|---|---|
| Unit Cost | Highest | 25–40% below U.S. | Lowest at volume |
| Lead Time | 2–8 weeks | 5–15 business days | 6–14 weeks + shipping |
| Time Zone | Same | Same — Pacific | 12–15 hr offset |
| Min. Order Qty | 1 pc | 1 pc — always | Often 100–5,000 pcs |
| Supplier Audit Access | Easy | 30–60 min from San Diego | International flight required |
| IP & NDA Protection | Strong | Strong — USMCA framework | Moderate to elevated risk |
| FAI / CMM Documentation | ✓ Standard | ✓ Every part, every order | ◑ Variable, requires oversight |
| Same-Day San Diego Delivery | ✓ | ✓ Daily Otay Mesa crossings | Not possible |
Documentation That
Meets Any Standard
Include your Supplier Quality Requirements at RFQ time. We confirm compliance before the PO is issued — not after production starts.
Signed declaration that parts conform to drawing revision and purchase order requirements. Included with every shipment as standard.
Mill certificate tracing material lot and heat number to the specified alloy, AMS designation, or FDA compliance grade. Included on every order.
Complete CMM dimensional report on every new part number — all drawing characteristics measured and reported against nominal and tolerance.
Statistical process capability reports (Cpk ≥1.33) for all key characteristics designated on the drawing. Available on request for production programs.
Full Production Part Approval Process packages for automotive and regulated industry programs. Level selection per customer SQAM or PO requirement.
Complete First Article Inspection Report per AS9102 standard for aerospace programs. Available through AS9100 Rev. D certified suppliers in our Mexicali network.
