One Partner . Six Connected Capabilities
Manufacturing Capabilities
From raw material to finished parts and complete assemblies, each capability links to a focused service page.
01
CNC Milling
For housings, brackets, plates, pockets, slots
and multi-face prismatic parts.
ENGINEERING REVIEW
Review datum strategy, cutter access, internal radii and setup count.
02
CNC Turning
For shafts, bushings, collars, threaded parts and rotational geometry.
ENGINEERING REVIEW
Review grip length, concentricity, runout, grooves and thread requirements.
03
5-Axis CNC Machining
For complex surfaces, angled features and parts that benefit from fewer setups.
ENGINEERING REVIEW
Review feature access, workholding, tool reach and inspection strategy.

Match material,
process and finish.
Material choice affects machinability,
forming, appearance, corrosion resistance
and cost. Surface requirements can also
change tolerances and the order of
operations.

Project-specific plastics
Anodizing · Coating · Plating · Appearance Control
Confirm finish specification, masking, color, surface zones and dimensional
impact during quotation.
CNC Project Evidence
One real case is more valuable than a list of claims.
Use a publishable JUNCHU project and explain the manufacturing judgment without exposing customer
identity or confidential dimensions.
Precision CNC-Machined Component
- Incoming material verification and supporting documents
- First article inspection before production, when required
- In-process checks on agreed critical dimensions
- Final dimensional and visual inspection
- Surface finish and packaging verification

What CAD and drawing formats can I upload?
You can upload the following CAD and drawing formats:
2D CAD: DWG, DXF, DWT
3D CAD: STEP, STP, IGES, IGS, SAT, SLDPRT, SLDASM
Drawing & image files: PDF, AI, EPS, PNG, JPG, TIFF, BMP
Please note that image‑based files are only for preview and cannot be edited as CAD data.
Can you support a one-piece prototype and later production runs?
What tolerances can you hold on custom aluminum parts?
How do you manage anodized color and cosmetic appearance?
How do you handle inspection, packaging, and international delivery?
