Prototype & Low-Volume CNC Machining in Vietnam
From a single prototype to small repeat batches, with drawing review before we quote, the right partner factory for each part, and inspection on every order.
From First Prototype to Repeat Orders
One supplier and one inspection standard across every stage, so you don’t have to requalify a new factory when the design is ready.
Prototype
Check fit and function. We review your drawing and flag manufacturability issues before quoting.
Design iteration
Engineering changes are supported between lots, and each revised drawing is reviewed before production.
Pilot and small-lot production
Parts are inspected at incoming material, in-process and final stages, not just at the end.
Repeat orders
Reorder the same drawing and receive parts made and inspected to the same standard.
Small Quantities Are Our Everyday Work
Low volume is not a side service for us. Our shipment records show how small many of our orders are.
Estimated from Yoshimoto Vietnam shipment records, using the average quantity per drawing within each shipment rather than exact per-drawing counts.
What Keeps Low-Volume Orders on Track
With few parts per order, there is no room for a bad lot. These steps are built into every job, whatever the quantity.
- Drawing review firstWe check manufacturability before quoting and suggest changes that reduce risk or cost.
- The right factory for each partEach order goes to the vetted partner best suited to its material, tolerance and quantity.
- Inspection, even for one pieceDimensional inspection based on your drawing and agreed acceptance criteria. Reports on request.
- One English-speaking contactFrom quotation to delivery, including engineering changes between lots.
What Drives Low-Volume Cost
At low quantities, setup and programming time is shared by only a few parts, so it becomes the largest part of the unit price. A few design choices can make a real difference.
- Tolerance only where it mattersTight tolerances on non-critical features add machining and inspection time.
- Choose available materialsCommon grades are sourced faster and at lower cost than special alloys or tempers.
- Simplify hard-to-machine featuresDeep narrow pockets and sharp internal corners need special tools and extra time.
- Group drawings in one orderSeveral parts in one order can share setup, inspection and shipping.
What to Send for a Fast Quote
The more complete your request, the faster and more accurate our quote. Missing details are fine; we will ask.
- 3D modelSTEP or IGES preferred.
- 2D drawingPDF, DWG or DXF with tolerances and notes.
- QuantityPrototype quantity and expected repeat volume, if known.
- Material and finishGrade, surface treatment and any heat treatment.
- Required delivery dateAnd the delivery address, for shipping time.
- Special requirementsInspection reports, material certificates or RoHS documents.
Industries We Support
What is your minimum order quantity?
There is no minimum. We machine single-piece prototypes as standard, as well as small batches and repeat orders.
How long does a prototype take?
Typically 7–14 days for machining, depending on complexity and factory workload. Air freight to the U.S. and other countries usually takes 3–5 days.
How quickly will I get a quote?
Within 3 business days, including feedback on manufacturability (DFM) when we see a risk or a cost-saving option.
Can I change the design between prototype and production?
Yes. Engineering changes are supported between lots, and we review each revised drawing before production.
Do you inspect prototypes and small batches?
Yes. Even for single pieces, we perform dimensional inspection based on your drawing and agreed acceptance criteria. Inspection reports are available on request.
What files do you need for a quote?
A 3D model (STEP or IGES) and a 2D drawing (PDF, DWG or DXF) with tolerances, plus quantity, material, finish and required delivery date. Dimensioned sketches are also accepted.
Start with One Prototype
Send your drawings, even for a single piece. We review manufacturability and reply with a quote within 3 business days.
