One project, several routes
Housings, shafts, brackets and finished hardware can be mapped to the processes each shape needs.
CUSTOM METAL PARTS · FACTORY REVIEW FROM YOUR DRAWING
Custom metal parts made to your drawing.
One machined component or a multi-part project: send a drawing, sample photo or parts list. We review each part’s geometry, material, quantity and critical features before quoting.
For drawing-defined industrial components—not catalog hardware or complete machines.

WHO WE ARE
A factory-direct route for the parts that do not fit a catalogue.
KEC Tour is a Dongguan-based, factory-direct team for OEM buyers sourcing non-standard metal components. CNC machining, sheet metal, die-cast blanks and finishing can be discussed in one project when the parts must assemble together.
See the company and quality workflow →WHY BUYERS WORK WITH US
Keep the whole assembly visible to the supplier.
Assembly-critical questions early
Point out mating faces, fits and datums so the review focuses on how the pieces work together.
A repeatable handoff
Carry the approved revision, sample decisions and inspection points into the batch quotation.
IS THIS THE RIGHT RFQ?
Check the scope before you send.
The right starting point is a drawing-defined component with a buyer who can describe how the part will be used.
Good fit for KEC Tour
- Custom parts defined by your drawing or sample
- One part or a list of different part numbers
- Prototype or repeat-batch requirements to review
Outside this page’s scope
- Stock hardware and retail purchases
- Complete machines or finished motors
OUR SERVICES
Different shapes need different manufacturing routes.
Tell us what the part must do. A shaft, enclosure and cast housing should not be treated as the same machining job.
CNC milling
Housings, brackets, plates and other features requiring pockets or mounting faces.
CNC turning
Shafts, sleeves, bushings and cylindrical interfaces.
Other metal routes
Sheet metal, die casting and combined-process inquiries reviewed for suitability.
Finish & inspection
Surface treatment and verification specified with the drawing and order.
PART-TO-PROCESS MATCH
Which part is closest to yours?
Start with the geometry you need; we will review the production route against your real drawing.
Select a part to load its interactive model.
INTERACTIVE 3D · REPRESENTATIVE GEOMETRY
Rotate the part. Inspect the features.
Rotate a representative housing, bracket, shaft or adapter. These models help discuss geometry; they are not customer-approved production CAD.
Model geometry illustrates part families only. Threads, tolerances and performance come from your approved drawing.ENGINEERING SPECIFICATION
Six details that decide the manufacturing route.
A useful quote distinguishes a cosmetic requirement from a feature that makes the assembly work. Mark the latter clearly.
| Decision | What to define | Why it matters |
|---|---|---|
| Approved revision | Drawing number, revision and any matching 3D file | Prevents pricing one version and building another. |
| Material and condition | Alloy, temper or hardness and any substitution rule | Changes the stock, tool plan and finish route. |
| Critical interfaces | Fits, datums, runout, flatness or sealing surfaces | Determines where process and inspection effort belong. |
| Quantity profile | Prototype quantity, repeat batch and forecast if known | Helps compare setup-heavy and repeatable routes. |
| After-machining work | Heat treatment, coating, marking and protected areas | May change dimensions and handling after machining. |
| Acceptance evidence | First article, measurement report, material record or packing rule | Lets the quote include the proof procurement expects. |
Use this as a discussion guide. Final requirements come from the approved drawing, application standard and purchase documents.
RFQ FILE PACK
A useful RFQ starts with four details.
A complete pack reduces clarification rounds. You can still start with a sample or partial drawing.
Drawing pack
Use a 2D PDF and 3D STEP/STP file if available; show the current revision.
Bill of parts
Give each part number its material, prototype quantity and expected repeat volume.
Assembly context
Mark mating parts, interface dimensions, datums and any functional surfaces.
Purchase notes
Add target date, finishing, inspection documents and packing instructions.
No finished drawing yet? Send the sample photo and the dimensions you know; identify what remains undecided.
Start an RFQ ↗INSIDE THE WORKSHOP
See the workshop behind the review.
See machining and part handling in the actual workshop. The footage demonstrates the environment; your approved drawing and quotation control the delivered part.
ILLUSTRATIVE ASSEMBLY STUDY
See how separate metal parts meet in an assembly.
This illustrative bracket/base/fastener animation shows why mating faces, hole locations and the approved revision matter across a multi-part RFQ. It does not validate a customer assembly.
APPLICATION & SOURCING DECISIONS
Compare the same scope—not just the unit price.
For a multi-part RFQ, ask how each quoted line handles setup, sample approval and repeat supply.
Part-by-part clarity
Each part number needs its own revision, material, quantity and process route. A combined project should still have clear line items.
Prototype versus production
A sample route may be useful for validation, while repeat volume can justify different tooling, fixturing or inspection.
The hidden handoffs
Finishing, deburring, assembly fit, documentation and packing affect the delivered part even when the cut geometry is simple.
SAMPLE TO BATCH
Move from prototype approval to a controlled repeat order.
The handoff should preserve the approved revision, the features checked on the sample and the agreed finish and packing.
- 01
Identify each part
We separate the requirements for every drawing and revision.
- 02
Match the route
We review machining access, material and any additional process needs.
- 03
Clarify open points
We ask about missing dimensions, quantities or acceptance criteria.
- 04
Confirm the quote scope
The proposed route, finish and inspection are recorded for your order.
INSPECTION & DOCUMENTATION
Agree the inspection evidence before ordering.
Availability and scope of reports or certificates are confirmed in the quotation. Product renders illustrate geometry; they are not records of a delivered customer part.
- Dimensional inspection for specified features
- Material and finish documentation requested with the RFQ
- Revision and quantity alignment for repeat work
FACTORY DOCUMENTATION
Review the evidence behind the process.
Certificates are issued to Dongguan Xuxiang Precision Metal Products Co., Ltd. KEC Tour is the website brand, not the named certificate holder. Ask us to confirm the manufacturing entity, certified site, scope and applicability to your order.

Need an NDA before sharing files?
Tell us before you upload controlled drawings. We can discuss the confidentiality agreement and the permitted review scope first. Share only files your organization authorizes you to disclose.

BEFORE YOU SEND
Useful answers for your RFQ.
Can I send more than one part?
Yes. Identify the drawing number, revision, material and quantity for each line item.
Is a photo enough to start?
A photo can start a discussion. Dimensions and specifications may be needed for a reliable quotation.
Can we agree an NDA before sharing drawings?
Yes. Contact us to discuss the NDA and permitted review scope before uploading controlled files.
Are the product images actual customer parts?
No. They show representative geometry. Your approved files define the production part.
Send the difficult part—or the whole parts list.
Include part numbers, revisions, quantities and the features that matter at assembly. We can then respond to the project, not just one isolated drawing.
